In this paper, the optimization strategies of routing protocols are analyzed with respect to energy utilization of sensor nodes in Wireless Sensor Networks (WSNs). Routing protocols are in charge of discovering and maintaining the routes in the network. Different routing mechanisms have been proposed to address energy optimization problem in sensor nodes. Clustering mechanism is one of the most efficient mechanisms which cater to the requirements of energy conservation in wireless sensor networks. To check the efficiency of different clustering scheme against modeled constraints, the authors select five cluster based routing protocols; Low Energy Adaptive Clustering Hierarchy (LEACH), Threshold sensitive Energy Efficient sensor Network (TEEN), Stable Election Protocol (SEP), Distributed Energy Efficient Clustering (DEEC), and hybrid energy efficient distributed protocol.
