Broadcasting is an effective routing paradigm for data dissemination in vehicular ad hoc networks (VANETs). One concern that arises with broadcasting is the broadcast storm problem, which would cause node contentions and data collisions, and thus degrade the transmission efficiency of a network. This paper proposes a Dynamic trAnsmission delaY based broadcast (DAYcast) protocol for a VANET. To alleviate...
Routing is a critical issue in vehicular ad hoc networks (VANETs). This paper considers the routing issue in both vehicle to vehicle (V2V) and vehicle to infrastructure (V2I) communications in VANETs, and proposes a Moving dirEction and DestinAtion Location based routing (MEDAL) algorithm for supporting V2V and V2I communications. MEDAL takes advantage of both the moving directions of vehicles and...
This paper proposes a Destination Information based Probabilistic (DIP) routing protocol for vehicular sensor networks (VSNs). In DIP, the destination information of a packet is used to determine candidate neighbors and the moving pattern of a vehicle is used to help select the next hop for forwarding data. The design goal of this protocol is to minimize the packet loss in the network and thus improve...
