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 recent years, routing has been the most focused area in ad hoc networks research. On-demand routing in particular, is widely developed in bandwidth constrained mobile wireless ad hoc networks because of its effectiveness and efficiency. Most proposed on-demand routing protocols are built and relied on single route for each data session. Whenever there is a link disconnection on the active ro...

This paper reviews security issues on Adhoc network and Ad hoc On-Demand Distance Vector (AODV) protocol. In Adhoc network, active attack i.e DDOS, blackhole and malicious nodes attack can easily occur. These attacks can decrease the performance of the communications protocol. In this paper, AODV was chosen as the basic protocol to perform simulations due to the fact that the AODV protocol can ...

wireless ad hoc networks are composed of independent nodes managing the network without any infrastructure. the connection between nodes is provided by sending packages and by trusting to each other. therefore, using efficient and certain protocols is the essential requirement of these networks. due to special characteristics of wireless ad hoc networks such as lack of a fixed infrastructure, t...

This paper presents an algorithm to modify the Ad Hoc OnDemand Distance Vector (AODV) routing protocol in order to improve the routing performance in motorway surveillance systems. The proposed protocol has all the characteristics of the original AODV routing protocol since it follows all the steps of the route discovery and route maintenance mechanism of the original AODV routing protocol. The...

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 ...

This paper proposes an Energy Aware Routing Protocol (E-AODV) based on AODV which incorporates local routing of intermediate nodes to increase the lifetime of the network .NS2 (Version 2.34) [1] simulator is used for the simulation of new protocol and AODV protocol for the performance parameters packet delivery ratio and delay. This implementation demonstrates that how small changes in the prin...

Developments in computer communications and networks enabled the deployment of exciting new areas. Meanwhile, Efficient network communication technologies also promote development routing protocols. AODV(Ad hoc On-Demand Distance Vector Routing, AODV) protocol has invulnerability to different mobile attributes agent nodes damage scenarios. However, this performance can not meet needs multi-agen...
