LEACH has many problems in election of cluster head and energy consumption control

aiming at these problems

propose improvement for generation mode of LEACH protocol cluster head. The improved LEACH protocol is to add specific location information of network nodes and current remaining energy information of network node in original LEACH protocol

alternative cluster head node spacing and simulated annealing algorithm are introduced in cluster head selection stage. The simulation results on NS2 show that the improved LEACH protocol makes selection of cluster head more reasonable

and the whole network lifetime is extended 50 %

and amount of receiving data of base station is increased by 175 %.
