AODV-DSR Hybrid Reactive Routing Protocol and its Generalization for Mobile Ad-Hoc Networks

Mobile Ad-hoc networks (MANETs) play a vital role in wireless communication, and their efficient deployment and uses require effective routing protocol workable in highly resource limited environment. This paper proposes a hybrid reactive routing protocol using AODV and DSR as they are two representative routing protocols for MANET. Both follow the same RREQ and RREP messages for on-demand route establishment, however, they use different tactics for keeping route information─ one considers forward- and reverse-links and other uses all intermediate nodes for data transmission. In this paper, we combine both of them and propose a hybrid routing protocol comprising links and path-nodes, and as a result, it becomes more reliable and efficient routing protocol than either of them. In addition, it is shown that the proposed hybrid routing is a generalization of AODV and DSR. We provide detail performance analysis of our hybrid protocol.
