OPTIMIZING ROUTIGN IN WIRELESS SENSOR NETWORKS BY LABTEENERGY AWARE PROTOCOL BASED ON LEARNING AUTOMATA

[摘要] An approach to lengthening lifetime in sensor networks is balancing energy usage in network nodes. This can be done by selecting appropriate paths for sending data and monitoring the amount of passing traffic. In this paper, we propose an energy aware protocol, LABTE, which uses learning automata in order to find appropriate paths for sending data packets to balance energy usage in nodes. Results have been compared with other protocols. Simulation results show that proposed protocol in field of energy usage in nodes and as a result lengthening network lifetime and also by monitoring the amount of passing traffic, in field of data sending delay show better performance than others.
