First Working Conference
(sponsored by IFIP WG 6.3 and 6.8)
We propose four different group mobility models and describe a mobility pattern generator called grcmob to be used with the ns-2 simulator. We compare the behavior of a classical reactive routing protocol, the Dynamic Source Routing (DSR) protocol and we perform a thorough evaluation of its behavior using as a reference the behavior obtained with the random waypoint mobility model.
We observe the high variability of the results and the need to know exactly the behavior of the system and the impossibility to define a unique proposal which is general to whatever environment. We make evident that also the mix of inter- and intra-group communication has a strong impact on the routing protocol performance and should therefore be taken into consideration when tuning or designing a routing protocol. Finally, we demonstrate that the presence of groups forces the network topology to be more sparse and therefore the probability of network partitions and node disconnections grows.
