Comparison of OMNET++ and other simulator for WSN simulation

Wireless sensor networks have gained considerable attention in the past few years. In this article we present a WSN simulator - OMNET++. Through compare with some well-known simulator proves OMNET++ has better performance than NS2 and OPNET. We demonstrate the use of the WSN simulation by implementing Directed Diffusion protocols, and perform performance comparisons (in terms of the execution time incurred and memory usage) in simulating WSN in OMNET++ and NS2. The simulation study indicates the WSN in OMNET++ is much more scalable than NS2. It showed that OMNET++ is better than other simulator in large-scale WSN simulation.
