Embodiment Construction

[0062] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but should not be used to limit the scope of the present invention.

[0063] The invention discloses a data transmission method in an opportunistic network, such as figure 1 shown, including the following steps:

[0064] S1. The data demand node sends a subscription request to the base station;

[0065] S2. The base station extracts the interest attribute of the subscription request, and generates a retrieval number according to the interest attribute;

[0066] S3. The base station queries to obtain the corresponding data node according to the retrieval number, and sends a solicitation notice to the data node;

[0067] S4. The data node receives the solicitation notification, and if it agrees to send data to the demand node, it is a response node, and sends a resource respon...

Abstract

The invention discloses a method for transmitting data in an opportunity network. The method comprises the following steps: adding a base station in the opportunity network to acquire, process and analyze data information, designing a source node recommendation strategy based on geographic positions, motion features and reputation values, dynamically regulating the quantity of resources shared by a data demand node sending a resource request through reputation feedback and updating node reputation values according to the document similarity, so that the decay rate of edge node reputation values is retarded on one hand, and higher matching requirements are provided for a community active node on the other hand. According to the method disclosed by the invention, the resource utilization rate and the transmission efficiency are effectively improved, and the transmission efficiency and the success rate are greatly improved on the premise of reducing the time delay and the resource consumption.

Description

technical field [0001] The invention relates to the technical field of opportunistic network transmission, and more specifically relates to a data transmission method in an opportunistic network. Background technique [0002] With the popularization of smart terminals and the subsequent rapid growth of mobile data services, it is expected that there will be 7.1 billion mobile devices by 2015, and the data service volume of centralized mobile networks will increase to 26 during 2010-2015. times. In areas densely populated with mobile terminals such as urban commercial centers, campus communities, and stations, the needs of mobile users often cause a large number of cellular data services, and the amount of data required will exceed the carrying capacity of the cellular network, causing heavy loads on base stations, thereby reducing network quality. It is also a problem that causes the request business to fail to respond. In order to reduce the base station load and improve ...
