Improving Energy Efficiency Using LEARN Algorithm for Wireless Sensor Networks
A number of energy-aware routing protocols were proposed to seek the energy efficiency of routes in Multihop wireless networks. Among them, several geographical localized routing protocols were proposed to help making smarter routing decision using only local information and reduce the routing overhead. However, all proposed localized routing methods cannot guarantee the energy efficiency of their routes. In this paper, the authors first give a simple localized routing algorithm, called Localized Energy-Aware Restricted Neighbourhood routing (LEARN), which can guarantee the energy efficiency of its route if it can find the route successfully.
