Comparison of DEEC with Other Cluster Based Routing Protocols for Wireless Sensor Networks

In this paper, the optimization strategies of routing protocols are analysed 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. DEEC is a distributed clustering scheme for heterogeneous wireless sensor networks. It is the most energy efficient protocol for heterogeneous node energy network. In order to analyze this protocol, 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 modelled constraints, we compare four cluster based routing protocols; Low Energy Adaptive Clustering Hierarchy (LEACH), Threshold Sensitive Energy Efficient sensor Network (TEEN), Stable Election Protocol (SEP) and Hybrid Energy Efficient Distributed protocol(HEED) and Constrained anisotropic diffusion routing (CADR)  . To validate our mathematical framework, we perform analytical simulations in MATLAB by choosing number of alive nodes, number of dead nodes, number of packets, number of cluster heads, as performance metrics.
