Abstract:

For the blindness of cluster head election, the imbalance of energy consumption in the cluster and the substantial energy consumption in communication with a hop in low energy adaptive clustering hierarchy (LEACH) protocol, an improved algorithm of the LEACH protocol based on "game of life" is proposed. First the cluster head election mechanism based on the estimate of the node residual energy is optimized. Then the sleeping scheduling model based on "game of life" and communication of multi-hops which used its neighbor nodes as forwarding nodes are proposed. Network simulator version 2 simulation shows that the improved protocol effectively prolongs the survival time of the wireless sensor networks and increass the amount of data transmission.

Key words: wireless sensor networks, game of life, cluster head election, sleep scheduling
