Abstract :
Fading is fundamentally different in ad hoc and cellular mobile wireless networks. Herein we show a way to simulate small-scale and large-scale fading on links in an ad hoc network and present simulation results for a multipath shadowed outdoor environment. We study fundamental discrepancies between ad hoc and cellular networks and find that link performance is worse for the ad hoc case, but, more interestingly, the performance gap shrinks with "increased mobility".
