TAB-PRRA: Improved Link Repair Decision Mechanism for Ondemand Routing in MANET
Journal Title: IOSR Journals (IOSR Journal of Computer Engineering) - Year 2014, Vol 16, Issue 1
Abstract
The traditional AODV protocol uses a fixed hop count based threshold as a basis for deciding when to invoke Local Repair or Source Repair in case of a link break. The problem arises with this type of repairing mechanism is that the network is not clear that at which time what algorithms needs to be applied. So some condition has to be identified on the basis of which the decision can be taken. Also the decision must be preemptive so that the loss of data can be avoided before occurrence. In this paper, a Threshold Alarm Based Preemptive Route Repair Algorithm (TAB-PRRA) for Multi-Hop Local repair in ADOV is presented and simulated. It focuses on measuring those parameters which provides an prior information of link failure before its occurrence and also if the link break occurs that the network must know the time to start the route discovery. The approach offers efficient utilization of network resources such as energy and bandwidth.
