COLLECTIVE APPROACH FOR MANETS TO SUPPORT PACKET LOSS AND DELAY SENSITIVE APPLICATIONS IN REAL

Abstract

Mobile ad hoc network is network with different applications are developing with different service requirement. In particular multimedia applications and other real-time applications e.g. voice transmission. MANET is a autonomous network where communicating entities can communicate without the aid of any downlink power controller called base stations. Therefore there is no centralized control over links. Further the link quality varies due to mobility of the nodes. Existing routing protocols like AODV or any other QoS routing does not account for changes in link quality once the path is established. Therefore the performance of such a system degrades with high mobility. Hence in this work we emphasis on incorporating link quality estimation based on mobility prediction along with Node's geographic location and incorporate same in the routing decision further new routes are accumulated and the primary transmission path is changed in case a better route in terms of link quality is obtained. We mingled the idea of link stability and power consumption with Location aware routing to propose a new technique for MANET that reduces control overhead and provides better performance.
