具有单跳与多跳路由选择功能的层次路由协议

Hierarchical Routing Protocol with a Selection of Single-hop or Multi-hop

分析了层次路由协议中聚类内部以及聚类之间单跳与多跳路径的能量消耗情况.提出了一种混合路由方案,节点自主地根据剩余能量,与邻居节点的距离,以及当选首领的总时间来竞争聚首,同时为了减小节点远距离通信带来的能量开销,无论是在聚类内部还是聚类之间,节点在数据传输阶段均遵循单跳与多跳路由的选择规则.通过和LEACH,DEEG协议对比实验,结果表明新路由方案不仅均衡了聚类负载,还增加了数据收集次数,有效提高了传感器节点的利用率.

Through analyzing the energy dissipation of single-hop and multi-hop path within as well as between clusters in the hierarchical routing protocol,a hybrid routing method was proposed. Nodes compete for cluster head autonomously according to residual energy,the distances with neighbor nodes and total time of being the elected head. Meanwhile,in order to reduce energy cost of telecommunication,nodes are all followed the selection rules of single-hop and multi-hop routing during data transmission step whether in the internal clusters or between them. By the compared experiment with LEACH and DEEG,the results show that this new routing method not only balanced the cluster load,but also increased the times of data collection and improved the utilization of sensor nodes effectively.
