Energy Optimization in Wireless Sensor Network

Energy consumption is a major challenge in wireless sensor network (WSN). Most of the routing algorithms focus on energy efficient paths, For the analysis of such algorithms at low cost and in less time; we believe that, simulation gives the better approximation. Therefore, in this paper, we are proposing a simulation model for WSN. Literature survey is done on energy-aware routing protocols, in which, it is found that, Minimum Total Transmission Power Routing (MTPR) and Minimum Battery Cost Routing (MBCR) Protocol, most comprehensively captures tradeoffs of energy efficiency and network lifetime respectively. Proposed simulation model is implemented using Qualnet 4.5 and applied to MTPR and MBCR to analyze its performance. Through this study, we lay a foundation for further research work on enhancements in extending the network lifetime of WSN. Experimental result shows that there is always a tradeoff between energy efficiency and network lifetime.
