Analysis of Routing Protocols for Wireless Sensor Networks

Abstract: Wireless Sensor Networks (WSNs) are large networks made of numerous sensor nodes with sensing, computation, and wireless communication capabilities. Due to the achievement in low-power digital circuit and wireless communication, many applications of the WSN are developed and already been used in habitat monitoring, military object and object tracking. The energy of nodes is the most important consideration among them because the lifetime of Wireless Sensor Networks is limited by the energy of the nodes. This work focuses on analyzing the optimization strategies of routing protocols with respect to energy utilization of sensor nodes in Wireless Sensor Network (WSNs). Different routing mechanisms have been proposed to address energy optimization problem in sensor nodes. Clustering mechanism is one of the popular WSNs routing mechanisms. To check the efficiency of different clustering scheme against modeled constraints, three cluster based routing protocols are selected; Low Energ
