| 摘 要： | 无线传感网络中部分区域节点事件频发,形成能耗热点,引发网络负载不均衡,缩短网络生命周期?针对无线传感网络能量受限的问题,在分析研究混合能量有效的分布式路由算法(hybrid energy-efficient distributed clustering approach,HEED)的基础上,提出了一种簇内圆状分割的无线传感路由算法(circle cluster HEED of radius adjustment,CCRA-HEED)?该算法以非定长半径对层次分簇后的簇内感知区域进行非均匀圆状再分割,并从数学角度进一步分析网络能量的均衡特性?仿真结果表明,CCRA-HEED算法能够有效减少无线传感网络的能量消耗,获得较长的网络寿命和均衡的能量负载?

| Abstract: | Frequent events in wireless sensor network,which would lead to the formation of energy consumption hotspots,can result in load imbalance and short lifetime in the network.Based on a study on HEED,an inner cluster circle-division algorithm(CCRA-HEED)is proposed to save the limited energy in WSN.The inner cluster regions in the hierarchy network are further divided into several circle-shaped areas via variable radius,and then the energy balance is also further analyzed mathematically.The simulation results show that the proposed CCRA-HEED can dramatically reduce the energy consumption in WSN,and network lifetime is prolonged notably with a balance energy load. |
