Ad Hoc Network Information Dissemination for Offline Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for issuing and acquiring parking lot and business information are inconvenient for users, as they require accessing the internet and are costly for businesses to maintain, especially for small or medium-sized enterprises.
Innovation Solution
A method and system utilizing an ad hoc network with information issuing nodes and client nodes, where information is broadcast and updated throughout the network, allowing users to issue and acquire information without internet access, using a decentralized and self-organizing wireless network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If websites are used to issue information, then information can be accessed by clients, but it costs a lot of money and is difficult to maintain for businesses
Solution Approach 1:
The patent extracts the information issuance function from complex website systems and implements it through simple ad hoc network nodes. Each business or parking lot can be represented by a basic node that broadcasts information locally, eliminating the need for expensive website infrastructure while maintaining information availability.
Solution Approach 2:
The patent replaces expensive, complex website systems with inexpensive ad hoc network nodes that can be easily deployed and removed. These nodes use standard wireless communication capabilities already present in most devices, making them cost-effective for small and medium-sized businesses without requiring professional web development or maintenance.
2Reliability
If websites are used to issue information, then information can be accessed by clients, but it requires tedious searching and screening and generates access expenses for clients
Solution Approach 1:
The patent segments the information dissemination system into local ad hoc network zones around each business or parking lot. Instead of clients searching through a centralized website, information is broadcast locally to nearby devices, making information acquisition immediate and convenient without requiring internet access or tedious searching.
Solution Approach 2:
The patent introduces ad hoc network nodes as intermediaries between information sources and clients. These nodes broadcast information directly to nearby devices, acting as local messengers that eliminate the need for clients to actively search or pay for internet access, thereby improving ease of operation.
3Productivity
If ad hoc network is used to issue information, then information can be disseminated timely and efficiently, but network stability may be affected by dynamic topology changes
Solution Approach 1:
The patent embraces the dynamic nature of ad hoc networks by designing the information broadcasting mechanism to work seamlessly with changing topologies. Nodes dynamically discover and adapt to network connections, allowing efficient information dissemination despite mobility and topology changes, thus converting the stability challenge into a flexibility advantage.

AI summary
The present disclosure discloses a method for issuing information including: an ad hoc network including an information issuing node and a client node is established; when a user to which the information issuing node is attributive desires to issue information, the information issuing node stores information issued by the user, broadcasts the information issued by the user to the ad hoc network and notifies all other nodes of the ad hoc network to update information of the information issuing node. The present disclosure also discloses a system for issuing information and a method and system for acquiring information. The methods and systems make it possible to implement timely and efficient issuing and acquisition of information.
