A parallel simulator has been designed for the evaluation of wireless, multihop, mobile networks. This paper describes the process of porting the simulator from a sequential to a parallel environment. Parallelization is critical in large radio networks, where the complexity of radio propagation models, channel access schemes and interference patterns makes sequential simulation very time consuming - in the order of several hours for 100 nodes experiments. With parallel execution, speedups of up to tenfold have been observed on a 16 processor SP/2, making large net work simulations viable.
