无线传感网络能量有效负载均衡的多路径路由策略

Energy-efficient and Load-balancing Multipath Routing Scheme for Wireless Sensor Networks

由于无线传感网络中网络节点的能量受限性,路由成为最受关注的问题.鉴于多路径传输既要考虑能量节约,又要考虑负载均衡,提出了一种新型能量有效负载均衡的多路径路由算法.该算法综合考虑了路径的跳数、节点剩余能量和网络的能量状况,数据沿着最小跳数或路径关键能量比较高的路径传输,降低了网络的能量消耗,也避免关键节点的过量负载.实验结果验证了和传统的AODV算法相比该算法在分组投递率、端到端时延和死亡节点出现的数量方面的优势.

In wireless sensor networks, routing has been the most focused area for its nodes＇ energy exhaustibility. Whereas multipath must provide load balancing along with the energy-awareness, a scheme called Energy-efficient load-balancing multipath routing is proposed. This scheme analysis path hopcount, residual energy of nodes and energy status of sensor networks. The packets can be transmitted along the multiple paths according to the minimum hop or their Key Energy Ratio, reduces the network energy consumption and avoid heavy traffic on some critical nodes, The simulation results verifies that the scheme provides the best packet delivery ratio, end to end delay and node numbers with zero energy.
