Mobility Aided Context-Aware Forwarding Approach for Destination-Less OppNets

Abstract

Opportunistic networks enables the devices to communicate as and when the opportunity rises. This property of OppNets has been explored in routing approaches in a similar operating manner as the traditional infrastructure networks. Specifically, context-aware routing approaches have been the major focus of OppNets in the recent literature. However, the potential of OppNets also extends to data dissemination in destination-less networks. Forwarding approaches in such a network need context such that the data dissemination is favored without the necessity to reach a particular set of users or a particular destination. Hence, the context-awareness need to be defined differently for destination-less OppNets as compared to OppNets in destination-oriented scenarios. In this paper, we propose a mobility aided context-aware mechanism for data dissemination in destination-less OppNets based on mobility based local information available at individual nodes. The results show that the proposed approach achieves high delivery ratios as epidemic routing while reducing the overhead by 70% as compared to epidemic routing.
