基于机会网络中社交关系的转发机制

摘要

The existing forwarding mechanism is unable to fully adapt to the judgment and analysis based on social relations in social networks.This paper proposed a novel forwarding mechanism in opportunistic networks by establishing the classification of social relationships and building a network of social relationships tree model .The mechanism set up the node weight that de-termined by the node level, the availability and reliability of social relations.Through the path weight, it selected the most valuable message delivery path.The simulation results show that the proposed forwarding mechanism effectively reduces the number of message’s copies and routing overhead.%由于现有的机会网络转发机制不能完全适应社会网络中基于社交关系的判断与分析，为此通过建立社交关系的分类，构建机会网络中的社会关系树结构模型，提出了一种新的转发机制。该机制设置了节点权重值，由节点所处的层次和社会关系的可利用性及可靠性决定。通过路径权重值，选择最有价值的路径进行消息的传递。通过仿真实验，所提出的转发机制有效地降低了网络中的消息副本数和降低了路由开销。
