Comparative Simulations of WSN

In this paper we present the results of a study wit hin the CRUISE Network of Excellence. Within CRUISE we have simulated a simple scenario for Wireless Sensor Networks with three different simul ation tools: NS-2, OMNeT++ and OPNET. The scenario investigated is that of a f ire fighter entering a building and deploying sensor nodes in different rooms. Data col lected from the sensor nodes is transmitted to the fire fighter and the incident co mmander at the other end. The simulation tools are compared regarding their ease of implementing the scenarios, collecting the metrics delay, throughput as well as comparability of the results.
