摘要：In the performance assessment of an ad-hoc protocol, the protocol should be verified under genuine circumstances including, but not restricted to, an effective transmission range, inadequate buffer space for the storage of messages, illustrative data traffic models, and a mobility model. Deterioration of average speed as the simulation growths, a variance between the extensive duration distribution of nodes and the initial one, and sometimes the unpredictability of the model are the problems caused by simulation of mobility models. A mobility model emulates the actual world movement of mobile nodes and is essential component to simulation based analysis. So, satisfactory analytical and real demonstration of mobility is a very significant subject in simulation of mobile ad hoc networks. Our domino effects point out that the ad hoc protocols are certainly inclined by these mobility models. Extensive simulations have been conducted for different conditions of network density and node mobility for each of the four mobility models and also for different values of the degree of randomness parameter for the Gauss-Markov mobility model.
