摘要
首先深入分析了两种典型的分布式的节点定位算法,并从定位精度及能量消耗两个方面给出了定量分析结果。在此基础上提出了改进的定位算法,BB RP算法。通过仿真试验,在定位精度和能量消耗两个方面与原有算法进行定量的分析比较。结果表明,BB RP算法虽然在定位精度略低于原有的算法,但是在能量消耗和覆盖速度两个指标上有了较大的提高,使得无线传感器网络的生命周期延长。
Two typical distributed node location algorithms were analyzed in this paper firstly,and it gave the analysis result of location precision and energy consumption. A modified node location algorithm, named BB _ RP algorithm, was presented. By simulating test, it is compared withthe primary algorithms about node location precision and energy consumption. Comparing result showed that the node location precision of BB _ RP is a little lower than that primary algorithms, but it makes great improvement in energy consumption and coverage speed and delays the lifetime of wireless sensor network.
