Classification of routing protocols in wireless sensor network

Abstract

Lifetime of a node is a critical concern in wireless sensor network (WSN). Nowadays networks are becoming large, so data collected is becoming even larger, which all consume great amount of energy leading to an early death of a node. Therefore, researches are done to minimize the energy used in data sampling and collection to prolong the life time of a network. Through years several routing protocols are proposed and enhanced. In this paper we introduce several factors to consider before choosing and implementing a routing protocol.
