Integrating Distributed Wireless Simulation Into Genesis Framework∗

The design and evaluation of ad-hoc wireless networks introduce several unique challenges not present in wired network environment. The most significant among them include the communication medium shared between potentially thousands of nodes, the mobility of the network nodes, and the unpredictable nature of the wireless channels with problems such as fading, obstacles and interference. That makes the simulation a valuable tool to design and optimize the wireless networks and to ensure their interoperability with wired networks. In this paper, we present wireless version of Genesis, a system for on-line, scalable simulation of communication networks using distributed computing. The presented version is implemented over GloMoSim, a simulation library for wireless network simulation. We describe challenges of implementing such a wireless version of Genesis, its performance, as well as its interoperability with Genesis components simulating wired networks.
