Hypergraph Modeling Scheme with Joint Contact Schedule and Prioritized Data Traffic Constraint for Opportunistic Internet of Vehicles

In this paper, we explore the hyper graph modeling scheme with joint contact schedule and prioritized data traffic constraint for Opportunistic Internet of Vehicles (OppIoVs). Firstly, we present the concepts of the real contact and the virtual contact between two vehicle nodes by taking into account both the real connection constraint of the physical link and the constraint of the priorities of different data traffic in OppIoVs. Then we devise the real contact schedule metric for the real contact between two vehicle nodes along the scheduled link. Moreover, the hybrid contact homeostasis incorporating joint contact schedule and prioritized data traffic constraint between two vehicle nodes along the scheduled link is also designed. Finally, we propose the hyper graph modeling scheme by devising the different algorithms to obtain the hyper edges under two different cases including the case of intermittent real contact and the case of persistent virtual contact.
