针对目前无线传感器网络研究中网络能量利用率低和通信链路不可靠等问题,提出一种基于最优刚性图的网络拓扑优化算法.该算法通过建立包含链路质量和能量两方面内容的链路权值函数来构建链路可靠性强、能量利用率高的网络拓扑结构.研究结果表明,所构建的拓扑具有平均节点度低和链路性能好等优越特性.仿真结果表明,与现有拓扑控制算法相比,所提出的算法能够更有效地减少能量消耗,从而延长网络寿命.
Aiming at the problems of low network energy utilization and unreliable communication links in wireless sensor networks, this paper proposes a network topology optimization algorithm based on the optimal stiffness graph. This algorithm builds a network topology that includes both link quality and energy Road weight function to construct the network topology with strong link reliability and high energy efficiency.The results show that the proposed topology has the advantages of low average node degree and good link performance.The simulation results show that, Compared with the topology control algorithm, the proposed algorithm can reduce the energy consumption more effectively and prolong the network lifetime.
