三维固定分簇异构传感网络路由协议

Three-dimensional fixed-clustering heterogeneous sensor routing

基于高楼三维空间中家居监测的应用背景,提出了一种三维空间中LEACH路由协议的改进算法:三维固定分簇异构传感网络路由协议(3D-FHSR)。在3D-FHSR中,使用了异构网络的方式让部分能量充裕的节点固定充当簇头节点,并且事先划分好簇的区域范围,这样减少了簇头选举时的能量消耗,同时增加了整个网络的能量。3D-FHSR还改进了LEACH协议的通信模式,减少簇间长距离通信的次数。仿真结果表明,3D-FHSR协议比LEACH协议更能延长网络的生命周期。

Based on the background of three-dimensional high-building home habitation monitoring application scenarios, a routing protocol improving LEACH protocol in three-dimensional space is proposed, called 3D-FHSR （three-dimensional fixed-clustering heterogeneous sensor routing）. 3D-FHSR uses heterogeneous network mode which lets some energy-infinite sensor nodes fixed act as cluster head, and partition the area range of cluster beforehand, This manner can reduce energy consumption in the period of cluster-head selection and increase energy to the whole networks. Meanwhile, 3D-FHSR improves the communication mode in LEACH. Thismethod can reduce the number of long-distance communication over cluster. Simulation results show and verify that 3D-FHSR can prolong the networks＇ lifetime than LEACH.
