基于BA无标度网络的WSNs拓扑优化模型
WSNs Topology Optimization Model Based on BA Scale-Free Network
摘要
Abstract
Due to the limited energy of wireless sensor nodes,the maximization of the network lifetime has become one of the most important problemsin the optimization of the network topology.This paper presents a wireless sensor networks topology optimization model (WTOM) based on BA scale free network.Some super nodes are introduced into the network that is divided reasonably by using particle swarm algorithm.The virtual force field driven by multiple factors is established between nodes and the deployment position of super nodes is adjusted by the virtual force.Thus,the nodes' energy consumption is balanced and the robustness of invulnerability is improved by protecting key nodes.Both the theoretical analysis and experimental results demonstrate that the obtained netw ork model not only keep the characteristics of BA scale free network,but also has the characteristics of small world.Moreover,the proposed model can extend the network life cycle and raise the network energy saving in data collection.关键词
