Abstract-In recent years, a number of routing protocols for Mobile Ad Hoc wireless networks have been developed and have found many applications including multiple routing protocols In Ad-Hoc mobile network, multi-hop wireless links are popular applications as they are less routing overhead in order to reduce the network congestion as well as bandwidth utilization. In this paper, we studied the Ad-Hoc Ondemand Distance Vector (AODV) Routing protocol with deep analyzing. Then we have proposed a Direct Forward Routing Protocol scheme (DFRP) where the new approach is built on demand and maintained by direct forward mechanism through a double functions agent node. This double function forwarding node was built and equipped with at least two hopes connectivity.In other words, if an intermediate node has discovered that the next forwarding node to the destination is moved from the network and it is no more its neighbor,then on behalf of the moved node; the current node has ability to forward direct to the next hop (the moved node’s neighbor) for the moved node. This means that the moved node neighbors perform as a neighbor of the current node. In addition, the source node will not broadcasts a Route Request packet on its entire neighbors, it just broadcasts half of nodes in order to avoid the network congestion and deliver the packet to the destination routes with minimum overhead. This new protocol comes up a very useful mechanism which eliminates the route regenerating by the source as well as repair or local repair and many other mechanisms when a route breaks due to node mobility or failure.This study aims at enhancing the AODV Quality of Service (QoS) capabilities by DFRP to mitigate the route breakdown of ad hoc networks.
