摘要：由于无线传感器能量受限,最大化网络生命周期成为优化网络拓扑首要考虑的问题。基于BA无标度理论,提出了一种WSNs拓扑优化模型(WTOM)。在网络中引入超级节点,结合粒子群算法合理地划分整个网络;在节点间建立多因素为导向的虚拟力场,利用虚拟力调整超级节点的部署位置,实现网络能量的均衡消耗,通过对关键节点的保护,提高网络的抗毁鲁棒性。经理论分析和实验证明,该网络不仅继承了BA无标度网络的特征还具有小世界特性;同时该动态拓扑延长了网络的生命周期,提高了网络面向数据收集的节能性。
Due to th e l im i ted en erg y of w ire le ss s en so r n o d e s , th e maxim iza tio n of th e n e two rk lifetime has become one of the mos t impor tant problems in the optimizat ion of the network topology. This paper presents a wireless sensor networks topology optimizat ion model （WTOM） based on BA scale free network. Some super nodes are introduced into the network that is divided reasonably by using part icle swarm algor ithm. The vir tual force field driven by mul t iple factors is establ ished between nodes and the deployment posi t ion of super nodes is adjus ted by the vir tual force. Thus, the nodes＇ energy consumption is balanced and the robustness of invulnerabi l i ty is improved by protect ing key nodes. Both the theoret ical analysis and exper imental resul ts demonst rate that the obtained network model not only keep the character ist ics of BA scale free network, but also has the character ist ics of small world. Moreover , the proposed model can extend the network life cycle and raise the network energy saving in data collection.
