Multipath Routing Protocol With Backtracking for Mobile Ad Hoc Networks

A Mobile Ad hoc NETwork (MANET) is characterized by multi-hop wireless links in the absence of cellular infrastructure and frequent host mobility. In this paper, a new on-demand routing protocol is proposed, named On-demand Routing protocol with Backtracking (ORB), for multi-hop mobile ad hoc networks. Suppose a source host wants to deliver a message to a destination in a MANET. First, the source host issues a request to search the destination. When a node receives the request packet, it gets a hop count value which can point the way to the source. This node broadcasts the request packet to its neighbors. When a destination receives this request, it issues a reply back to the source.
