A modified LEACH algorithm in wireless sensor network based on NS2

Aiming to the disadvantage of the short lifetime due to the uneven distribution of the cluster head, and single-hop path communication style in the LEACH protocol. By analyzing the classic clumps and routing protocol LEACH, and changing the way of producing cluster head and the communication way between the base station, the modified algorithm reduces the setup time and the cluster head communication distance and balances the node energy consumption. The simulation results showed that the modified algorithm had efficiently reduced energy consumption of wireless sensor network nodes, and made survival time of network much longer than traditional LEACH algorithm.
