Simulation is an essential tool for evaluating the performance of wireless protocols and applications because of its cost effectiveness and its high level of control over the simulated system. As the research community envisions increasingly complex applications in areas like mobile social networks and wireless sensor networks, the need for trustworthy simulation of core communication protocols increases. This paper presents a comparative evaluation of several IEEE 802.11 and IEEE 802.15.4 simulators. The paper defines a set of simple experiments that are intended to highlight handling of back-off and contention.
