Embodiment Construction

[0045] There are mainly two phases in the implementation. The first stage mainly completes the establishment of mobile models and the acquisition of activity indicators. The second stage mainly transmits information according to routing conditions.

[0046] In the first phase 0-T period, the nodes move or stay still in the manner described by a1, generate node encounter data, and generate node activity indicators.

[0047] 1) Construct a mobile model, generate the favorite community and the probability of going to each node, and generate mobile information such as the destination community / direction / speed / stay situation. Set the simulation area as a square area of ​​1000×1000 square meters, set several square areas with an area of ​​100×100 in this area as communities, and regard each person holding a wireless communication device as a node, each node Go to three communities with higher probability and other communities with lower probability. Such as figure 1 As shown, no...

Abstract

The invention relates to a mobile social network routing method based on node activeness and energy factors. The routing method is composed of three parts: a, establishing a mobile model; b, constructing an activity indication parameter of the node; c, establishing an information forwarding routing strategy based on activity and energy, a person of each handheld wireless communication device is regarded as a node, encountering information among the nodes is used for establishing activeness indexes of the nodes, an activeness threshold value is set according to the activeness condition, a routing strategy is formulated, the relation between typical information transmission performance indexes and energy consumption is considered, and excellent information transmission performance and energyconsumption ratio are sought. The problem of information transmission in a mobile social network is solved. By using the method provided by the invention, an appropriate activeness threshold value isset, and the optimal balance (best trade-off) between information transmission performance and energy consumption can be obtained.

Description

technical field [0001] The invention proposes a routing method based on node activity and energy factors for Mobile Social Networks (MSNs for short), which is mainly used to solve the problem of information transmission in the mobile social network and belongs to the technical field of computer wireless communication. Background technique [0002] With the development of wireless communication technology, mobile social network has received extensive attention. The mobile social network is a kind of Delay Tolerance Networks (DTNs for short). In DTNs, mobile users establish a distributed self-organizing dynamic network, there is no fixed network connection between mobile users, and the information transmission mode is store-carry-forward. In addition to possessing the characteristics of traditional DTNs, mobile social networks exploit the social characteristics of mobile nodes to improve information transfer performance. [0003] Many protocols for MSNs have been proposed, i...
