A Novel Message Driven Local Repair Algorithm for MANET
Journal Title: International Journal of Computational Engineering and Management IJCEM - Year 2015, Vol 18, Issue 1
Abstract
Mostly MANET is used for emergency situation like disaster management which has the task of supplying QoS in an effort to provide the right information to the right place at the right time. In this scenario with the capability to send and receive reliable real-time video and voice packets, the involved network must be able to provide a certain level of QoS. So that the QoS impact in the face of network failures must be minimized in MANET like temporary emergency networks. In such a situation, when an intermediate node fails the network has no built in protocol to respond to this link breakage, the connection will have to be rerouted from the source and QoS will have to be re-established. This global fault-tolerance method means the source will have to recomputed and renegotiate a new QoS path which, depending on the network size, could be costly in terms of computation and communication time necessary for path negotiation (negotiation includes implementation of the new path). In contra, the proposed fault-tolerant algorithm makes it possible for the Intermediate nodes to efficiently repair the failed connection locally and reroute the packets to the destination.
