摘要
针对无标度的拓扑特性,提出一种基于无标度的无线传感器网络路由算法。该路由算法从平均度分布和节点吸附性的角度出发,采用多路径的设计原则,建立一种无标度网络模型,利用该模型建立无线传感器网络拓扑,同时节点具有信息融合能力,提高数据的冗余可靠性,降低网络吞吐量,使网络能量均衡,延长网络生命周期。仿真结果表明,该路由算法与针对无线传感器网络的一些路由算法Flooding、LEACH和NBEERP相比,在节点度分布、可靠性和总体性能评价方面效果显著。
Based on the topological characteristics of scale-free,a kind of wireless sensor network routing algorithm is put forward. From the perspective of the average degree distribution and the adsorption of nodes in this routing algorithm,multipath designing principle is adopted,which builds a scale-free network model. And wireless sensor network topology is established based on the model,nodes with information fusion ability at the same time,which improves data reliability redundancy and reduces network throughput. So network energy becomes balanced,which prolongs network life cycle. Simulation results show that the routing algorithm has more significant effect on the node degree distribution,reliability and overall performance evaluation in comparison with some other routing algorithms such as Flooding,LEACH and NBEERP.
