One of the key design criteria in Wireless Sensor Network is that of power conservation since all nodes are battery powered. According to researchers, due to the high importance of energy usage, it is highly desirable to define and measure the amount of energy a Wireless Sensor Network can spend to perform its goal efficiently. In this context a number of related efforts have been carried out. However there is a lack of widely accepted experimental energy models and simulators which are needed to accurately simulate and evaluate the efficiency of a protocol or application design. Thus the need to develop an improved energy efficient model and consequently an energy(oriented simulator for Wireless Sensor Networks crops up to meet researchers’ needs. For this purpose, an energy oriented model and simulator, called eMnSiM has been derived. This model considers the residual energy of a node. Residual energy is an important factor in prolonging the lifetime a Wireless Sensor Network. Moreover, eMnSiM model takes into consideration other parameters that directly or indirectly affect energy consumption. Thus eMnSim serves as a good experimental energy model which can be used by researchers to accurately simulate and evaluate the efficiency of several protocols or application.
