Purpose-Movement Assisted Routing for Group Mobility in Disconnected Mobile Ad Hoc Networks
As a challenged network, the Delay-Tolerant Network (DTN) generally has unpredictable delay for the packet delivery due to the insufficiency of the network connectivity. Thus, it is inadequate to support some time-sensitive applications. In this paper, the authors aim to mitigate this unpredictability of the delay in DTN to broaden its applications by proposing a new routing strategy to make use of the node mobility. Their designed solution is called Purpose-Movement Assisted Routing (PMAR) aiming for a more realistic mobility model, group mobility, which has been paid attention in many realistic scenarios.
