The influence of node mobility in Mobile Ad hoc NETworks (MANETs) has significant implications for system performance. A class of MANETs characterised by a sparse density of nodes coupled with a relatively short range of radio communication, results in a network topology that is disconnected most of the time.This wireless mobile ad hoc network is called an “opportunistic network” or “delay-tolerant” network. This paper presents some models in which the rate of information propagation within the opportunistic network is considered. Furthermore, a characterisation of the multicast time in the opportunistic network is developed.
