  abstract: "Ad hoc network is a set of nodes that are able to move and can be connected in an arbitrary manner. Each node acts as a router and communicates using a multi-hop wireless links. Nodes within ad hoc networks need efficient dynamic routing protocols to facilitate communication. An Efficient routing protocol can provide significant benefits to mobile ad hoc networks, in terms of both performance and reliability. Several routing protocols exist allowing and facilitating communication between mobile nodes. One of the promising routing protocols is DSR (Dynamic Source Routing). This protocol presents some problems. The major problem in DSR is that the route cache contains some inconsistence routing information; this is due to node mobility. This problem generates longer delays for data packets. In order to reduce the delays we propose a technique based on cleaning route caches for nodes within an active route. Our approach has been implemented and tested in the well known network simulator GLOMOSIM and the simulation results show that protocol performance have been enhanced. "

  abstract: "Routing protocols for ad hoc networks typically include mechanisms for route discovery and route maintenance. The performance of these protocols depends on the route maintenance mechanism they use. The movement of network nodes can cause routes to become unusable. A node on a route from a source to a destination may become unreachable from its predecessor node because of node movement. In this paper, we propose a predictive preemptive approach to route maintenance. Route maintenance is initiated when a link break is expected rather than waiting for the break to happen. To evaluate the approach, we have added it to the AODV routing protocol, and evaluated its impact on performance using detailed simulations. The simulation results show that the proposed approach can be expected to improve performance significantly. It can reduce communication overhead, decrease the number of breaks in active links, reduce end-to-end packet delays, and improve packet delivery ratio."
