A heuristic multi Criteria routing protocol in wireless sensor networks

Abstract

Most existing routing techniques are designed to reduce routing cost by optimizing one goal. In wireless sensor networks one parameter cannot satisfies all requirements of these networks. Therefore, it's required to consider multiple parameters simultaneously in the routing process for improving performance of the routing protocols. However, the multiple-criteria routing process leads to some increases in complexity f the routing protocol. Recently heuristic methods specially the learning automata were used in the optimization problem. Hence, in this paper, we propose a multi-criteria routing method which uses learning automata to choose the optimum route between the available routes. Results of our simulation present high improvement in compared to the other routing methods. © 2011 Springer-Verlag Berlin Heidelberg.
