Link Optimization Ad-Hoc On-Demand Multipath Distance Vector Routing for Mobile Ad-Hoc Networks

In mobile ad-hoc networks (MANETs), multipath routing is wildly researched for its superiority over single-path routing. Ad hoc on-demand multipath distance vector (AOMDV) routing protocol performs very well and has been extensively studied. We present an efficient multipath routing algorithm, called link optimization ad-hoc on-demand multipath distance vector routing (LOAOMDV). We use 4 bies information of the RREP (route request) packet, and present a new route reply process. The new routing protocol establishes the omitted reverse path and reduces the number of common node in several paths. This protocol can reduced the end-to-end delay, extend the network lifetime, and salvages packet timely, reduces the ratio of packet chaotic sequence. Specifically the protocol has no additional routing overhead. The simulation results proved that it is more effective.
