摘要：

LEACH-EB (energy-balancing routing algorithm based on LEACH protocol) was put forward 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 performance of network was analyzed under different values of k and a cluster head selection method using dynamic 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 every 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. © 2015, Huazhong University of Science and Technology. All right reserved.
