摘要: 针对LEACH低功耗自适应分簇路由协议的不足之处,提出一种基于虚轮数强制成簇的改进方法:当节点产生的随机数全部不理想时,启动一个只负责选簇的虚轮数强制帮助本轮成簇.经OP-NET仿真平台测试,改进后的路由协议提高了网络的性能.

Abstract: For the inadequacies of low power adaptive clustering routing protocols,a new modified forced cluster-head selection approach based on the virtual round was presented.A virtual round only responsible for selecting cluster of is started to help cluster-head selection when the random number generated by all the nodes are not ideal.The simulation on OPNET platform demonstrated that the modified routing protocol enables the whole network have a fine performance.
