基于消息重要性的机会网络能量均衡路由算法

Energy balanced routing algorithm for opportunistic network based on message importance

提出了基于消息重要性的能量均衡路由算法——MIEBR(message importance based energy balanced routing algorithm)。MIEBR对消息重要性进行度量,并根据消息转发收益确定消息的转发顺序和路由。在节点缓存空间不足时,MIEBR依据消息缓存价值进行缓存替换。实验结果表明,在缓存空间和能量受限的机会网络中,MIEBR均衡节点的能量消耗,降低了重要消息的传输延时,在投递成功率和延时等方面优于其他算法。

A new routing algorithm MIEBR(message importance based energy balanced routing algorithm)was proposed.MIEBR measures the importance of messages.It determines message forwarding order and routing by message forwarding profit.When cache space is insufficient,MIEBR performs cache replacement based on message cache value.Simulation results show that,in cache space and energy constrained networks,MIEBR balances energy consumption of nodes,and reduces the latency of important messages.It outperforms other algorithms in delivery rate and latency.
