Towards a Better Approach for Link Breaks Detection and Route Repairs Strategy in AODV Protocol

Abstract

This paper describes a parameterized approach to the Ad Hoc On-Demand Distance Vector (AODV) routing protocol using a network-simulator 2 (ns2). By utilizing two AODV’s protocol functions, which are HELLO messages and local route repair, we explore the more flexible approach on these two important functions, rather than a fixed setting within the default AODV protocol. HELLO message is used to detect the broken link, while the local route repair in AODV is used to fix and discover alternative routes in the event of route failure. In this paper, two functions to optimize AODV performance have been utilized. The first is link break detection time (Llb), using the HELLO message to detect link failure, and the second is link break position parameter (Lbp) for AODV’s local route repair. The results show that the default AODV setting does not yield the best results for most defined network scenarios. In some cases, improvement compared to the default setting can be as high as 38%, for local route repair strategies. This paper presents a potential flexible and parameterized approach for dealing with link breaks and route repairing strategies for AODV protocol.

Energy efficient hybrid AOMDV-SSPSO protocol for improvement of MANET network lifetime

“…For the detection of link breakdowns and route repairs in AODV, Azzuhri et al [19] suggested a better method. The HELLO message is used by the researcher to identify connection failure and to improve AODV performance.…”

Congestion Free Routing in MANET based on Node Reliability Supported AODV

“…The paper [4] is the survey paper in which authors elaborating the contribution of previous literature on congestion control strategies in MANET and discussed hop-by-hop and end-to-end potential mechanisms for transfer reliability and congestion avoidance for single-copy and multi-copy forwarding. Following issues remained unresolved: interaction of routing and congestion control, which are taken care by the proposed work, and improved local measures of node importance.…”

Hybrid Meta-Heuristic Aomdv-Acopso Optimization Routing Protocol in Manet

“…A routing protocol keeps track of routing information for connecting and neighboring nodes. In MANET, there are three types of routing protocols: Proactive, Reactive, and Hybrid [4].Pro-active (Table-driven) protocol is one in which mobile node has its own routing table, which keeps track of routes to all possible destinations [5]. It has the disadvantage of not operating well in large networks since because it contains the information of all available route therefore, the routing table entries get too huge.…”
