摘要 机会网络中的节点由于受理性实体所控制表现出不同的协作意愿,从而对网络性能产生显著影响,针对这种情况,提出了一种协作意愿感知的机会网络路由算法,该算法利用消息的平均转发时间来衡量节点间的协作意愿,根据联系概率为消息合理地选取转发节点,采用消息优先级机制来提高缓存和带宽的利用率。仿真结果表明,该算法能有效地改善网络性能。 Cooperative willingness of nodes significantly affects the performance of opportunistic networks due to being controlled by rational entities.Under this condition,a cooperative willingness perception based routing algorithm is proposed in this paper.The average duration of messages forwarding is utilized to measure the cooperative willingness between nodes;moreover,combining with the parameter of contact probability between nodes,the relay node can be selected reasonably.Further,in order to maximize the utility of network resources,message priority is considered.Results show that the proposed algorithm can effectively improve network performance.
