We describe the TeD/C ++ implementation of WiPPET, a parallel simulation testbed for mobile wireless networks. In this article we emphasize the techniques for modeling of radio propagation (long-- and short-- scale fading and interference) and protocols for integrated radio resource management in mobile wireless voice networks. The testbed includes the standards--based AMPS, NA--TDMA and GSM protocols, and several research--oriented protocol families. 1 INTRODUCTION Simulations of wireless networks differ considerably from simulations of wired networks in that they have to include modeling of the geographic environment and physical channel properties (fading and interference) which both have a profound effect on network performance. The simulations are dominated by very frequent calculations of received signal quality for each network node. Their significant computational demands are not easy to mitigate by parallel execution. In this work we describe radio modeling issues, entity..
