Abstract
The cluster head of LEACH algorithm was selected randomly in WSNs. It effects the distribution of clusters for the shadowing effect of obstruction in real scenarios. The network consumption is increased because of poor communication between nodes. A new selection method is presented to solve those problems in this paper. The logarithmic function is adopted to eliminate the shadowing effect of obstruction. The most suitable cluster is sorted out because the density of nodes is defined as the new threshold value. Simulation results show that the performances of new algorithm are obviously better than LEACH, ALEACH and Kost-LEACH algorithms. Compared with classical algorithms, the nodes utilization could enhance more than 2.0%, average energy consumption of the nodes is reduced by 9.1 J at least, and the probability of nodes failure to join the cluster could be decreased great than 3.7%.
