ABSTRACT In Mobile Ad hoc Networks (MANETs), multicast routing protocols are being faced the challenge of producing multi-hop routes under severe resource constraints such as battery power, limited bandwidth and dynamic network topology. Multicasting in MANETs is complex and the overall energy is to be conserved as much as possible while achieving good throughput. In this paper, an energy efficient Robust On-Demand Multicast Routing Protocol (ROMRP) has been proposed to increase the overall throughput and the lifetime of multicast session by efficiently monitoring the group leader in order to preserve the multicast session without affecting loss of data packets and network partitioning.

    ABSTRACT: In this paper, we present a diagonal-intersection-based routing (DIR) protocol for vehicular ad hoc networks. The DIR protocol constructs a series of diagonal intersections between the source and destination vehicles. The DIR protocol is a geographic routing protocol. Based on the geographic routing protocol, source vehicle geographically forwards data packet toward the first diagonal intersection, second diagonal intersection, and so on, until the last diagonal intersection, and finally geographically reach to the destination vehicle. For given a pair of neighboring diagonal intersections, two or more disjoint sub-paths exist between them. The novel property of DIR protocol is the auto-adjustability, while the auto-adjustability is achieved that one sub-path with low data packet delay, between two neighboring diagonal intersections, is dynamically selected to forward data packets. To reduce the data packet delay, the route is automatically re-routed by the selected sub-path with lowest delay. The proposed DIR protocol allows the mobile source and destination vehicles in the urban VANETs. Experimental results show that the DIR protocol outperforms existing solutions in terms of packet delivery ratio, data packet delay, and throughput.
