Abstract: For the characteristic of delay-tolerant and nodal mobility,a new multicast routing algorithm-EMRRP is proposed for the Delay Tolerant Mobile Sensor Network(DTMSN),in which,nodal energy should be considered when selecting the next hop with delivery predictability.Simulation results show that the proposed EMRRP achieves higher performance than PROPHET at the respect of delivery ratio and latency,and EMRRP algorithm is an effective routing solution in Delay Tolerant Networks(DTN).

摘要: 针对容迟移动传感器网络(Delay Tolerant Mobile Sensor Network,DTMSN)网络的容迟及节点的移动性特点,提出了一种新的基于概率预测的能量均衡组播路由算法(Energy-balanced Multicast Routing based Probability Probabilistic,EMRPP)。该算法采用到达概率选择路由下一跳的方式,且考虑了节点能量对算法性能的影响。仿真结果表明,EMRPP算法在数据传输率和平均传输延迟方面的性能要优于改进之前的PROPHET算法,是一种有效的容迟移动网络组播路由方案。
