无线传感器网络动态k值簇头选择方法
Cluster head selection method using dynamic k value for wireless sensor network
摘要
Abstract
LEACH-EB (energy-balancing routing algorithm based on LEACH protocol) was put for-ward based on LEACH-C (low energy adaptive clustering hierarchy-centralized) .In every period ,it divides the structure of network in the first round and updates the cluster heads in the next k rounds with network′s structure unchanged .By this way ,it can improve the performance of network further . However ,the network is difficult to obtain the best performance by using the fixed k .The perform-ance of network was analyzed under different values of k and a cluster head selection method using dy-namic k value based on LEACH-C was proposed .Its core idea is calculating a better k value based on the structure of network and nodes′current residual energy after dividing the structure of network ev-ery time .The simulation on OMNeT+ + (objective modular network testbed in C+ + ) shows that LEACH-CK can obviously delay the time of the first node′s death .At the same time ,the stability of network is improved .关键词
