“…In some cases, when link failure happens at an intermediate link, it's more beneficial to discover new route locally without resorting to end-to-end route discovery. Some of the approaches of the local repair mechanism have been proposed in [14], [15], [16], [17] and [18].…”

“…Several studies on locally recovered route have already being proposed to address the efficiency of source repairing in reactive routing protocols such as in [14], [15], [16], [17], [18]. This paper evaluates and compares the AODV's behaviour when several different route recovery mechanisms are applied in AODV to see the impact when a link breaks occurs in an active route.…”

Wireless Mesh Networks (WMNs) have become one of the popular key technology and solution for the new wireless implementation especially for wireless end user. One of the widely used routing protocols in WMNs is Ad-Hoc OnDemand Distance Vector (AODV) protocols. In this paper, we investigate the performance of AODV in situations of link failures due to mobility of nodes and consequent route recovery mechanism using ns2 simulators. We defined a different set of threshold for routing protocols to do local repair based on the link breaks location with respect to the total number of hops from source to destination. Packet Delivery Ratio (PDR) and Normalized Routing Load (NRL) or overhead were used as performance metrics in our simulations. For link-failure detection, HELLO message and Link Layer Feedback (LLF) were used separately in the simulations. Simulations were done by varying the number of sourcedestination pair and speed of the mobile node.

“…Due to its on-demand-based nature, AODV presents several problems that are mainly related to high packet drop ratios and high routing overheads (Alshanyour & Baroudi, 2008). These problems cause packet loss, collisions, high end-to-end delay and high latency, among others.…”

“…To alleviate the aforementioned route maintenance problem, researchers [3][4][5][6][7][8][9][10][11][12][13] have proposed mechanisms to reduce the number of transmitted control packets, in an attempt to reduce the energy and bandwidth usage. In such approaches, every node collects information about its neighbors by exchanging periodical control packets or by overhearing its neighbors' transmissions.…”
