This work focusses on analyzing the optimization strategies of routingprotocols with respect to energy utilization of sensor nodes in Wireless SensorNetwork (WSNs). Different routing mechanisms have been proposed to addressenergy optimization problem in sensor nodes. Clustering mechanism is one of thepopular WSNs routing mechanisms. In this paper, we first address energylimitation constraints with respect to maximizing network life time usinglinear programming formulation technique. To check the efficiency of differentclustering scheme against modeled constraints, we select four cluster basedrouting protocols; Low Energy Adaptive Clustering Hierarchy (LEACH), ThresholdSensitive Energy Efficient sensor Network (TEEN), Stable Election Protocol(SEP), and Distributed Energy Efficient Clustering (DEEC). To validate ourmathematical framework, we perform analytical simulations in MATLAB by choosingnumber of alive nodes, number of dead nodes, number of packets and number ofCHs, as performance metrics.
