摘要
针对无线传感器网络现有问题,提出一种基于能耗均衡和簇头优化的分簇路由协议,协议中引用了“节能点”“节能半径”和“独立节点”3个新的定义。结合最优簇头数、节点密度、距离因子和节点剩余能量设计新的阈值公式,优化节点入簇机制,弥补簇头选举过程中现有约束的缺点。实验结果表明,该协议在簇头选举阶段和簇形成阶段更具逻辑性,运行过程中节点能耗更小且更均匀,网络存活周期更长。
A cluster routing protocol based on energy consumption balancing and cluster head optimization is proposed to address the existing problems of wireless sensor networks and three new definitions of“energy-saving points”“energy-saving radius”and“independent nodes”are quoted in the protocol.At the same time,a new threshold formula is designed by a combination of the optimal amount of cluster heads,density of nodes,distance factor,and residual energy of nodes.The node clustering mechanism is optimized to compensate the shortcomings of the existing constraints in the cluster head selection process.The experimental results show that the protocol is more logical in the cluster head selection phase and the cluster formation phase,the energy consumption is less and more balanced and the life cycle of the network is longer during the operation process.
