Ad hoc networks meet the demands of spontaneous network setup. They are characterized by the use of wireless links, dynamically changing topology, multi-hop connectivity and decentralized routing mechanisms and decision-making. AODV and DSR are the two most widely studied on-demand ad hoc routing protocols. Previous studies have shown limitations of these protocols in certain network scenarios....

In many traditional On Demand routing algorithms in Ad hoc wireless networks, a simple flooding mechanism is used to broadcast route request (RREQ) packets when there is a need to establish a route from a source node to a destination node. The broadcast of RREQ may lead to high channel contention, high packet collisions, and thus high delay to establish the routes, especially with high density ...

This paper focuses on the improvement on the performance of AODV single path routing protocol concerning the route maintenance mechanism with security. This paper presents the performance comparison of proposed protocol Secure and efficient AODV (SE-AODV) with AODV routing protocol using NS2. As the reactive routing protocols is completely different from the proactive routing protocols because ...

in this paper, we propose a scheme to improve existing ad-hoc on-demanddistance vector (aodv) routing protocol by discovering and maintaining multiplenon-overlapped routes. our routing protocol is a multipath version of aodvrouting protocol that considers only the disjoint path. due to non-overlappingamong paths, when a link breaks in the network, only one of paths is expired. thepresented rout...

In mobile ad hoc networks, mobile devices wander autonomously for the use of wireless links and dynamically varying network topology. AODV (Ad-hoc on-demand Distance vector routing) is a representative among the most widely studied on-demand ad hoc routing protocols. Previous protocols have shown some shortcomings on performance. AODV and most of the ondemand ad hoc routing protocols use single...

The Ad hoc On-Demand Distance Vector (AODV) routing protocol is designed for use in mobile ad-hoc networks. As of the writing of this article, there exist several implementations of the AODV protocol for a range of operating systems (e.g., Unix/Linux, Windows), different devices (e.g. Notebook computers, PDAs) each developed using different techniques and programming languages. This paper descr...
