针对无线传感器网络节点能耗不均衡问题,通过对节点生命期建模,得出节点生命期受节点剩余能量和通信距离的影响,进而将两端节点生命期作为构建拓扑时边权重的影响因子,通过边权重控制节点权重,最终得出了一种能耗均衡的无线传感器网络加权无标度拓扑模型,并理论证明了该模型的点权、边权和节点度均服从幂律分布.实验结果表明,该模型具有无标度拓扑的强容错性,并有效的均衡了网络中的节点能耗,延长了网络的生命期.
Aiming at the problem of unbalanced energy consumption in WSN nodes, the lifetime of nodes is affected by the residual energy and the communication distance of nodes by modeling the lifetime of nodes. Then, the lifetimes of nodes at both ends are taken as the influencing factors Finally, a weighted scale-free topology model of wireless sensor networks is obtained by controlling the weight of nodes by edge weights. The power-law distribution of node weights, edge weights and node weights of the model is proved theoretically The results show that the proposed model has the advantages of scale-free topology with strong fault tolerance and effectively balances the node energy consumption in the network and prolongs the lifetime of the network.
