基于距离分区的多级异构无线传感器网络成簇算法
A multilevel heterogeneous clustering algorithm based on distance partition for wireless sensor networks
摘要
Abstract
To prevent node premature death in a wireless sensor network ( WSN) caused by long distance inter-node com-munication and effectively prolong the life cycle of the network , an energy efficient multilevel heterogeneous cluste-ring algorithm based on distance partition for WSNs , called the MHCADP, was proposed.The algorithm divides the monitoring area into three parts , and deployes three types of nodes according to the distance from each monitoring area to the base station .In the cluster head election process , it elects the cluster head node according to the pro-portion of average energy and residual energy of the node , allowing the node with high initial and residual energy to have more opportunities to become cluster heads than the low energy nodes .In addition, during the data transmis-sion , it chooses the single hop or multi hop according to the distance from the base station to the node and self -re-sidual energy .In order to verify the validity of the algorithm , its experimental results were compared with the algo-rithms of low-energy adaptive clustering hierarchy (LEACH) and stable election protocol (SEP), and it shows that the MHCADP can effectively reduce the network energy consumption and balance the network load , so that the net-work stability cycle and life cycle are extended by more than 50%.关键词
