【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。
[Abstract]:Due to the limited energy of wireless sensor, maximizing the network life cycle becomes the most important problem to optimize the network topology. Based on the scale-free theory of BA, a WSNs topology optimization model, (WTOM)., is proposed. The super node is introduced into the network, and the whole network is divided reasonably with the particle swarm optimization (PSO). A multi-factor oriented virtual force field is established between nodes and the deployment position of super nodes is adjusted by virtual force to realize the balanced consumption of network energy. Through the protection of key nodes the robustness of the network is improved. It is proved by theoretical analysis and experiments that the network not only inherits the characteristics of BA scale-free network but also has small-world characteristics, and the dynamic topology prolongs the lifetime of the network and improves the energy saving of the network for data collection.
