Poorva Shukla, Neeraj Shrivastava . A Novel Link Break Distance (LBD) and Pre-emptive Threshold Alarm (PTA) based Link Repair Approach for MANET. International Journal of Computer Applications. 70, 4 ( May 2013), 42-48. DOI=10.5120/11953-7773
Mobile ad hoc network is a temporary wireless network having movable mobile nodes as the only element of network. For transmission of data individual nodes behaves as a router. A during this process of routing operations the motion of nodes & environmental factors like traffic, delays etc causes the link break occurs between the nodes & data is lost. AODV is an on demand distance vector routing protocol. This work focuses on improving the performance & fault tolerant routing in MANET. It has two mechanism named as source repair & local repair for dealing with this link repair. But the decision is very complicated that which algorithm is applied at what instance. Node does not know the triggering condition of starting those algorithms. Also when this link break occurs during the data exchange then loss of data occurs. So there must be mechanism which is able to inform us prior the condition of link failure. This work proposes a novel Link Break Distance & Pre-emptive Threshold Alarm (LBT-PTA) mechanism for this decision making based on prior information. This information will give the continuous assessment of link condition. We define some triggering points at which decision is made based on threshold value. Also the hop count index according to distance is calculated to apply source or local repair algorithm. Initial experimental analysis shows that the proposed approach is going to provide effective results than any other existing approaches.
