Effect of Layers on Simulation of Wireless Sensor Networks
Obidul Islam, Sajid Hussain · 2007
This paper investigates the effect of simulation of lower layers on performance evaluation of energy-efficient multi- hop routing techniques designed to maximize network lifetime. A customized simulator is used to show the simulation results where the effect of lower layers, packet collisions, and overhearing is ignored. Then, an open-source simulator, J-Sim, is used to analyze protocols while considering MAC layer and packet collisions. The simulation results show that customized simulator gives very different performance evaluation as compared to J-Sim that provides the complete protocol stack.
