一种非均匀部署传感网的能量空洞缓解方法
A Type of Energy Hole Mitigation Strategy for Non-uniformDeployed Sensor Networks
摘要
Abstract
In Wireless Sensor Networks (WSN),nodes near the center tend to consume more energy as they are responsible for receiving and forwarding data from the whole network,which leads to a non-uniform energy consumption among nodes,that is so called the "energy hole problem".To prolong network lifetime and balance energy consumption in the cluster-tree based sensor network,a type of energy hole mitigation strategy in a circular network has been proposed.Network has been divided into several virtual annuluses for multi-hop transmission and nodes have been non-uniformly deployed in it.Moreover,for balancing energy consumption on data uploading,the number of nodes in the inner annulus is more than that in the outer one.According to the residual energy and the communication distance of its neighbor,each node has chosen an optimal parent in the adjacent annulus for data uploading.Simulation results have shown that this method could effectively prolong network lifetime by comparing with other energy hole avoidance algorithms and has also performed well on balancing energy consumption in the multi-hop transmission network and could effectively mitigate the energy hole problem.关键词
