基于无标度网络的无线传感器网络拓扑演化模型研究
Study on the topology evolution modeling of wireless sensor networks based on scale-free network
摘要
Abstract
In view of the survivability of wireless sensor networks ( WSNs) , two topology evolution models for WSNs based on a scale-free network are proposed from the angle of complex networks. The models firstly use a clustering algorithm to achieve the cluster heads, uniform distribution, and then make the topology evolution among cluster heads according to a certain connection strategy. The corresponding topology evolution algorithms are given according to the proposed models, and the dynamic characteristics of the models are analyzed. The simulation results show that the network topologies formed by the new models are more fit for the practical applications of WSNs and have a good survivability, a further improved robustness due to the consideration of the node residual energy and the node saturation when designing the models.关键词
