根据机会网络中节点较稳定的社会属性,提出了一种兴趣社区检测机制,将机会网络中节点的兴趣爱好量化,根据节点间兴趣爱好相似性进行兴趣社区划分.利用节点在运动过程中形成的社区,综合考虑节点的社区属性和节点间历史接触信息,设计了兴趣社区路由算法.兴趣社区路由由社区内路由和社区间路由组成,路由机制是选择与目标节点在同一兴趣社区且与目标节点接触较多的节点作为中继节点完成数据包转发.通过仿真实验验证兴趣社区路由策略的合理性和有效性.仿真结果表明,所提出的兴趣社区路由算法能有效降低网络开销和时延,提高了投递率.
According to the more stable social attributes of the nodes in the opportunistic network, a community detection mechanism of interest is proposed, which quantifies the interests of nodes in the opportunistic network and divides the communities of interest according to their similarities and interests. Community, considering the community attributes of nodes and historical contact information between nodes, the interest community routing algorithm is designed.The community routing of interest is composed of intra-community routing and inter-community routing, and the routing mechanism is to select the target community in the same interest community and the target node The more contact nodes are used as relay nodes to complete the packet forwarding.The simulation results verify the rationality and effectiveness of the interest community routing strategy.The simulation results show that the proposed interest community routing algorithm can effectively reduce the network overhead and delay The delivery rate.
