“…The neighbor node, in turn, will check its own route table and find its best next hop node to forward the packet, thus creating a localized detour. AODV-AP (AODV with accessibility prediction) [11] follows the same paradigm by keeping a track of all "accessible" nodes. Multipath and multipoint relays-(MPR-) based AODV (MMDV) [12] is a hybrid variation of AODV and the link state OLSR protocol.…”

Node mobility in mobile ad hoc networks (MANETs) causes frequent route breakages and intermittent link stability. In this paper, we introduce a robust routing scheme, known as ad hoc on-demand multipath distance vector with dynamic path update (AOMDV-DPU), for delay-sensitive data transmission over MANET. The proposed scheme improves the AOMDV scheme by incorporating the following features: (i) a routing metric based on the combination of minimum hops and received signal strength indicator (RSSI) for discovery of reliable routes; (ii) alocal path updatemechanism which strengthens the route, reduces the route breakage frequency, and increases the route longevity; (iii) akeep alivemechanism for secondary route maintenance which enables smooth switching between routes and reduces the route discovery frequency; (iv) apacket salvagingscheme to improve packet delivery in the event of a route breakage; and (v) low HELLO packet overhead. The simulations are carried out in ns-2 for varying node speeds, number of sources, and traffic load conditions. Our AOMDV-DPU scheme achieves significantly higher throughput, lower delay, routing overhead, and route discovery frequency and latency compared to AOMDV. For H.264 compressed video traffic, AOMDV-DPU scheme achieves 3 dB or higher PSNR gain over AOMDV at both low and high node speeds.

“…At that point when any network node [3] wants to send the data to another node it needs to broadcast a route request packet for [4] a new connection [5]. Other AODV nodes forward this message, and when the route request message received at Target node then it replies by route reply packet.…”

A Mobile Ad-hoc Network (MANET) is a collection of wireless mobile nodes forming a temporary network without using any centralized access point, infrastructure, or centralized administration. Data transmission between two nodes in MANET's may be requires multiple hops as the nodes transmission range is limited. Mobility of the different nodes makes the situation even more complicated. Multiple routing protocols especially for these conditions have been developed during the last few years, to find optimized routes from a source to some destination.Ad-hoc network suffer from the lot of issues and congestion and security are the major issues which lead to severe degradation of network throughput and increases the routing overheads. This paper presents Optimized AODV which the modified version Enhance local repair AODV by improving its Route Error message format. The result shows that OAODV performs better in terms of routing overhead and end to end delay than AODV. The simulation is done through network simulator ns2 gives a detailed comparison of research on AODV. Open research direction is also discussed to serve as a starting point to protocol design and evaluation

“…An enhancement to AODV is proposed in [83], which uses joint nodes' packets delivery records, current nodes' traffic load and routes' hop count information as route selection criteria to select low delay and more stable routes. The Load Balancing AODV (LB-AODV) scheme [75] is a modification of AODV to meet load balancing requirements.…”
