Description

[0001] The invention relates to a method for establishing a local ad-hoc network for energy and computing power exchange according to claim 1. Furthermore, the invention relates to a connection system for operating such a method.

[0002] The efficient distribution of energy typically depends on local energy grid operators and can be controlled across national borders. To this extent, electric vehicles or motor vehicles can also participate in energy distribution as energy suppliers or energy storage devices, particularly through bidirectional charging.

[0003] US 20 2000 772 40 A1 discloses a system that allows vehicles to communicate with other communication participants.

[0004] The object of the invention is to further develop a method and a connection system in such a way that a particularly simple communication between at least two entities for the exchange agreement of energy and / or computing power is possible.

[0005] This object is achieved by a method having the features of patent claim 1 and by a connection system according to the invention. Advantageous embodiments and further developments can be found in the dependent claims, as well as in the description of the advantages and the description of the figures.

[0006] A first aspect of the invention relates to a method for establishing a local ad hoc network for the exchange of energy and computing power using a transmission protocol, in which requests and / or offers are transmitted between communication partners via the ad hoc network. Upon acceptance of a request and / or offer, the exchange of energy and computing power between the corresponding communication partners is initiated. To increase data security, the requests and / or offers are divided into data fragments, with each communication partner only being released, delivered, or granted access to the data fragments assigned to it. This prevents one communication partner from gaining complete access to the entire data communication, thereby increasing security and data protection in the network.Each data fragment therefore contains only a portion of the entire information, meaning that the complete content can only be reconstructed and made available once the fragments have been combined by authorized entities. The ad hoc network is a dynamic network that can be used for the exchange of energy and computing power between different communication partners, in particular electric vehicles, charging stations, or mobile devices. A transmission protocol enables secure communication within the network, particularly in the area of ​​data protection, by regulating data transmission and the exchange of requests and / or offers. The fragmentation of the data is intended to ensure that each communication partner receives only the data fragments relevant to them, thus preventing unauthorized access to complete information.This fragmentation and restricted access authorization minimize the risk of sensitive information being compromised and increase data protection in a distributed network where various unknown entities can operate without having complete control over all communications.

[0007] The method for establishing the local ad hoc network for energy, power, and computing power exchange using the transmission protocol can also include the following procedural steps for communication between the communication partners: Sending a message from the first communication partner to the ad hoc network with a request regarding energy and / or computing power requirements. Accordingly, the first communication partner is represented here as the sender of the request, which includes a data module through which it can be wirelessly electronically coupled to a connection system for operating the method, whereby the message is then forwarded to third parties.

[0008] In a further method step, a message is sent from the second communication partner, which is different from the first communication partner, to the ad hoc network with a first offer for the request. Accordingly, the second communication partner here is a second entity that has received the request from the first communication partner and makes a counter-offer to the request. This counter-offer is therefore forwarded, in particular via the network or directly, and made available to the first communication partner for selection. Likewise, in a third method step, a message is sent from a third communication partner, which is different from the first communication partner and the second communication partner, to the ad hoc network with a second offer for the request.This approach ensures that not only the second entity that received the request, but at least a third entity also receives the request and can submit a second offer, allowing the first communication partner to choose between the first offer and the second offer. For this purpose, the first communication partner is provided with a variety of offers, allowing them to select the best possible exchange services.

[0009] In a further procedural step, the first communication partner either records and / or accepts the first offer and / or the second offer, or generates a further request. This means that the first communication partner now has the choice of accepting one of the offers or creating a further request that is better tailored to the preferences of the other communication partners.

[0010] In a further procedural step, upon acceptance of an offer, an exchange of energy and computing power is initiated between the first communication partner and the communication partner corresponding to the accepted offer. This means that the first communication partner has selected one of the offers and has reached an agreement with the communication partner to whom the accepted offer belongs, thus enabling the exchange of energy and computing power to begin.

[0011] To increase data protection, the data is not only divided into fragments during communication between the communication partners, but is also encrypted during transmission over the ad hoc network. These measures prevent unauthorized communication partners from accessing the entire data. Each communication partner receives only the data fragments relevant to them, and even in the event of unauthorized access, the information is unusable without the remaining fragments. This combination of fragmentation and encryption ensures the confidentiality and integrity of the transmitted data, thus ensuring that the process is carried out securely until consent is obtained, and that the start of the energy and computing power exchange takes place reliably.

[0012] In an advantageous embodiment of the invention, upon receipt of the first offer and / or the second offer, a further request is transmitted to the second communication partner and / or to the third communication partner. As previously mentioned, the offer transmitted to the first communication partner after the request is reviewed again, and a counter-request is transmitted so that the respective communication partners can adjust their respective offers, thereby leading to a better understanding between the respective communication partners.

[0013] In another advantageous embodiment of the invention, it is provided that upon receipt of the first offer and / or the second offer, a further request is transmitted to the ad hoc network. This means that the respective requests and offers are not transmitted directly between the respective communication partners, but rather that they are first transmitted via the ad hoc network. This means that the ad hoc network receives the respective requests and offers and then transmits them accordingly to the respective communication partners, thereby also providing a security measure in the area of ​​data protection, for example.

[0014] In another advantageous embodiment of the invention, upon receipt of the further request by the second communication partner and / or the third communication partner, a respective further offer for the further request is sent to the first communication partner. This means that upon receipt of the counter-offer by the first communication partner, the respective further entities, namely the further communication partners, can adjust their respective offers to accommodate the renewed request. This is intended to improve communication and the respective preferences of the interacting communication partners.

[0015] In another advantageous embodiment of the invention, upon receipt of the further request by the second communication partner and / or the third communication partner, a respective further offer for the further request is sent to the ad hoc network. Here, too, the respective counter-offers are not transmitted directly to the first communication partner, but rather are transmitted via the ad hoc network, thus also providing security measures in the area of ​​data protection, making the connection system for providing this method particularly secure.

[0016] A further aspect of the invention relates to a connection system for operating a method for establishing a local ad-hoc network for energy and computing power exchange using a transmission protocol. The requests and / or offers, or the corresponding messages, can be divided into data fragments to increase data security. Accordingly, each communication partner is granted access only to the data fragments assigned to it. Furthermore, the connection system comprises all the components required to carry out data fragmentation and data transmission between the respective communication partners, as well as for data transmission. The connection system includes communication modules that enable the individual communication partners to connect to the network wirelessly or wired and to send and receive data packets.A central data processing and control unit coordinates communication between the entities, monitors the connections, and is equipped with algorithms to analyze requests, create or forward offers, and control the exchange of energy and computing power. This connection system can also set priorities to ensure that critical requests receive preferential treatment. The connection system also includes energy storage and computing power units, such as accumulators, supercapacitors, or computing modules, that can temporarily provide requested power. The transmission protocol defines the rules and procedures for secure data exchange.

[0017] To further formulate the first and second aspects of the invention, in other words, a wireless data and energy transmission system is provided for interaction between communication partners in a local ad hoc network. A local protocol of the communication partners defines which resources, such as computing power, data capacity, or energy, they offer or require. Standardized protocols for mobile ad hoc or mesh networks can be used. The communication partners can send and receive or transmit messages containing requests and offers in order to establish a direct connection for the exchange of energy and / or computing power based on a decentralized negotiation process.

[0018] A communication partner can be, for example, an electrically powered stationary vehicle or motor vehicle, a charging station, or a temporarily available electrical device. The communication partners have different energy sources and computing power. For example, a charging station has access to an energy grid but not to computing power. An example e-scooter, using solar panels, has the ability to store and / or transmit energy depending on the environmental factors, but has relatively low computing power. A mobile device has little energy available but comparatively high computing power.

[0019] Information about these power units is exchanged locally and / or anonymously via wireless and encrypted data transfers. This creates a local network among anonymous participants, who exchange their information on energy and / or computing power requirements. If suitable constellations for exchanging energy and / or computing power arise among the communication participants, the corresponding exchange occurs. The exchange can take place directly between the communication partners after the network has mediated the offers. Alternatively, the network can act as an intermediary to coordinate the exchange.

[0020] The process thus enables dynamic adjustment and renegotiation of the exchange conditions, whereby, based on the received offers, further requests and offers can be generated and / or transmitted in order to find the best possible resource combination. Processes that can calculate such constellations are technically based on transmission protocols. For example, additional information can be added to the messages between the partners and communicated until they are identical, i.e., both negotiating or communication partners agree and accept the conditions of the energy and / or service exchange, subject to a suitable termination criterion. A cooperative negotiation strategy can be used here, in which options are exchanged until agreement is reached.

[0021] The process is distributed across multiple communication partners, providing additional data security. Each communication partner involved in the encrypted processing of the data receives only a portion of the data. This ensures that only smaller data packets are processed, increasing data protection, provided a sufficient number of communication partners are present. In this way, the communication partners only see fragments of the overall message and the entire computing process, further strengthening security and, above all, anonymity within the network.

[0022] In one application example, a user's mobile device, for example augmented reality glasses, may require corresponding computing power to recognize objects in the environment and for voice interaction with the user. However, this has a comparatively low energy reserve, low computing capacity, and little memory. After exchanging data with the local ad hoc network, other communication partners are found that can provide energy and computing power. Data processing for environmental object recognition is distributed. The device can, for example, use the e-scooter's excess solar energy meter as a communication partner without having to have sufficient computing and energy capacity itself. Communication initially takes place over the network until a direct connection to the suitable partners is established, which enables the exchange without the need for further use of the network.In a further development, a monetary or points-based benefit can also be agreed upon during negotiations between the communication partners regarding the use of the respective local resources. This allows for additional travel to participate and provide resources within the network.

[0023] A particularly advantageous aspect of the method described here is that it enables local optimization / improvement of energy distribution and a reduction in unused energy storage. Furthermore, it offers the potential for performance gains for devices or devices with low computing power. Furthermore, sustainability can be increased through the efficient use of existing unused resources. Finally, it also allows for a reduction in data transfer over long distances and processing in distant data centers or clouds, thus saving the energy required for data transmission and processing.

[0024] Further advantages, features, and details of the invention will become apparent from the following description of a preferred embodiment and from the drawings. The features and combinations of features mentioned above in the description, as well as the features and combinations of features mentioned below in the description of the figures and / or shown alone in the figure, can be used not only in the respective combinations specified, but also in other combinations or on their own, without departing from the scope of the invention.

[0025] It shows: Fig. 1 a diagram illustrating a method for establishing a local ad-hoc network for the exchange of energy and / or computing power by means of a transmission protocol and a connection system

[0026] In the figures, identical or functionally identical elements are provided with the same reference numerals.

[0027] Fig. 1 shows a diagram illustrating a method for establishing a local ADOC network 10 for exchanging energy and / or computing power using a transmission protocol and a connection system 1. The method comprises the following steps: A first communication partner 12 sends a message to the ad hoc network 10 with a request regarding the need for energy and / or computing power. To increase data security, this message is split into fragments so that no single communication partner has access to the complete request. A second communication partner 14, which differs from the first communication partner 12, then sends a message to the ad hoc network with a first offer for this request. This offer is also split into data fragments, allowing each communication partner access only to the fragments assigned to it. In addition, a third communication partner 16, which differs from both the first and second communication partners 12, 14, sends another message to the ad hoc network 10 with a second offer for the same request from the first communication partner 12.All messages and offers are also fragmented to protect the confidentiality of the transmitted information and to ensure that only authorized communication partners 12, 14 have access to the relevant data fragments.

[0028] The first communication partner 12 can then either record and / or accept the first or second offer or generate a further request. Upon receipt of the first or second offer, a further request is transmitted to the second communication partner 14 and / or to the third communication partner 16. In particular, a direct connection is established between the first communication partner 12 and the second communication partner 14 or between the first communication partner 12 and the third communication partner 16, without the ad hoc network 10 being or having to be used any further. Alternatively, upon receipt of the first or second offer, a further request can be transmitted to the ad hoc network 10, wherein the ad hoc network 10 continues to act as an intermediary and wherein other entities that did not participate in the first request can now also participate.

[0029] As soon as the further request is received by the second communication partner 14 and / or the third communication partner 16 and / or other entities, the latter sends a corresponding further offer for the further request to the first communication partner 12. The direct connection between the first communication partner 12 and the second communication partner 14 or between the first communication partner 12 and the third communication partner 16 remains.

[0030] Alternatively, a new communication is established with the additional entity without reusing the ad hoc network 10. Alternatively, however, the additional offer can be sent to the ad hoc network 10 by the second communication partner 14 and / or the third communication partner 16, or alternatively, it can be sent by the additional entity to the ad hoc network 10, whereby the ad hoc network 10 continues to be used as an intermediary. This is particularly important because the data exchange requires, or requires, data protection and security measures, which can be provided by using the ad hoc network 10.

[0031] If an offer is accepted, the exchange of energy and computing power begins between the first communication partner 12 and the communication partner 14, 16 whose offer was accepted, or alternatively, the additional entity. Alternatively, further requests can be made and / or transmitted until an offer is accepted, creating a cycle or loop.

[0032] A communication partner can be, for example, an electrically powered stationary vehicle or scooter 14, a charging station 16, or a temporarily present mobile device 12. The communication partners 12, 14, and 16 have different energy sources and computing power. For example, the charging station 16 has access to an energy grid but not to computing power. The e-scooter 14 has the ability to store and / or transmit energy via solar panels depending on the environmental factors, but has relatively low computing power. The mobile device 12 has little energy available but comparatively high computing power.

[0033] Information about these power units is exchanged locally and / or anonymously via wireless and encrypted data transfers of the connection system 1. In this way, a local ad hoc network 10 is established among the anonymous participants / entities, which exchange their information on energy and / or computing power requirements. The network 10 is based on a special transmission protocol provided for local ad hoc networks 10 and enables secure and efficient communication between the participants. The participants are electronically connected to one another via the connection system 1, which includes all the components required to carry out data transmission and transfer between the communication partners 12, 14, 16.

[0034] The method thus provides, for example, that the mobile device 12 sends a request regarding its energy and / or computing power requirements to the network 10. The e-scooter 14 and the charging station 16 then respond with offers to meet this demand. These offers are mediated by the network 10 or forwarded directly to the mobile device 12, thereby creating a choice between different options. The exchange can then take place directly between the communication partners 12, 14, and 16 after the network has mediated the offers. Alternatively, the network 10 can continue to act as an intermediary to coordinate the exchange and ensure that data protection and security measures are observed.

[0035] If suitable constellations arise among the communication participants for the exchange of energy and / or computing power, the corresponding exchange takes place. If an offer is accepted, the exchange of energy and computing power begins between the respective partners 12, 14, 16. It is also possible for the mobile device 12 to submit another request if the existing offers do not meet the requirements, thereby reactivating the network 10 to find additional communication partners and offers. This iterative approach enables flexible adaptation of the offers and ensures that the energy and computing power exchange is continuously optimized / improved to achieve the best possible benefit for all parties involved.

[0036] All communication partners 12, 14, 16 including the further entity each have the necessary components and / or modules to carry out the described method and to connect to the ad hoc network 10 and to the connection system 1 shown here. These components therefore enable particularly flexible and simple, yet dynamic networking as well as the exchange of energy and / or computing power in a distributed network environment.

[0037] In summary, the invention proposes a method for local ad-hoc exchange and agreement of energy and / or computing power.
