针对无线传感器网络节点能量有限且易失效的问题,利用复杂网络理论提出了一种能量有效的无线传感器网络无标度拓扑模型.该模型通过节点的剩余能量约束节点的发射半径,在拓扑演化过程中充分考虑节点剩余能量和节点度等因素,并引入能量调节参数和节点度调节参数,得出了一种幂率指数可以在[3,+∞)调节的无标度拓扑结构.动态分析和仿真实验结果表明,该模型具有无标度网络的幂率特性,且具有较好的容错性和能耗均衡的特点.
Aiming at the problem of limited and inefficient nodes in wireless sensor networks, an energy-efficient scaleless topology model for wireless sensor networks is proposed based on the theory of complex networks.In this model, the remaining energy of nodes constrains the emission radius of nodes, Which takes full account of node residual energy and node degree, and introduces energy adjustment parameters and node degree adjustment parameters, a scale-free topology with power index adjusted in [3, + ∞) is obtained. The simulation results show that the model has the power-efficiency characteristics of scale-free network, and has the characteristics of good fault tolerance and energy consumption balance.
