— Since the original work of Grossglauser and Tse, which showed that the mobility can increase the capacity of an ad hoc network, there has been a lot of interest in characterizing the delay-capacity relationship in ad hoc networks. Various mobility models have been studied in the literature, and the delay-capacity relationships under those models have been characterized. The results indicate that there are trade-offs between the delay and the capacity, and that the nature of these trade-offs is strongly influenced by the choice of the mobility model. Some questions that arise are: (i) How representative are these mobility models studied in the lieterature? (ii) Can the delay-capacity relationship be significantly different under some other “reasonable” mobility model? (iii) What would the delay-capacity trade-off in a real network be like? In this paper, we address these questions. In particular, we analyze, among others, some of the mobility models that have been used in the ...
