To improve the energy efficiency of wireless nodes so as to prolong the life of wireless mobile ad hoc networks(MANETs),an improved gateway selection algorithm was proposed that can enhance load balancing between the multiple gateways existing in a network.This analysis focused on the effects of balancing loads between multiple gateways on energy consumption in the whole wireless network.Quantitative analysis of energy consumption was also performed.The balancing ability of the new gateway selection algorithm for loads on multiple gateways was mathematically analyzed and its superiority shown.Simulation results indicated that the new load balancing gateway selection algorithm can prolong network lifetimes by up to 45%.Additionally,at the expense of a slight increase in network communication overhead,the new load balancing gateway selection algorithm can decrease network communication latency while increasing network throughput and the packet delivery ratio.
