基于能量的无线传感器网络路由策略研究

Research on Energy-aware of Wireless Sensor Network Routing Algorithms

针对传统路由策略算法数据传送效率低的问题,研究了基于能量的路由策略,分析无线传感器网络等通信网络的数据传输特点。在路由算法的设计中,考虑了邻居剩余能量和到目的节点的距离两个因素,提出了确定路由和概率路由两种路由策略。仿真实验结果表明,在同等条件下,平均分配初始能量的网络生命周期比按度分配初始能量的更长,确定路由比概率路由具有更好的数据传输特性,路由参数对确定路由数据传输的调节作用比概率路由更明显。

Aiming at the low efficiency of data transmission in traditional routing strategy algorithm,the energy based routing strategy is studied,and the data transmission characteristics of wireless sensor network and other communication networks are analyzed. In the design of routing algorithm,considering the two factors of the neighbor＇s residual energy and the distance to the destination node,two routing strategies are proposed to determine the routing and probabilistic routing. The simulation results show that under the same conditions,the average distribution of the initial energy network life cycle than by the allocation of the initial energy is longer,the data transmission characteristics of routing is better than the probability of routing,routing parameters to determine the regulatory role of routing data transmission than the probability of routing is more obvious.
