Link breakage time based QoS improvement in mobile ad hoc network

Route establishment between source and destination is a difficult process in mobile ad hoc network. Many approaches have been developed to find a route from source to destination without considering the stability of the nodes and its link life time. It affects the QoS parameters such as throughput, packet loss, delay, packet delivery ratio. So, in this proposed work a link breakage prediction algorithm is added to the AODV protocol. By using signal strengths from the received packets the link breakage time is predicted and sends a warning message to the source node of active route if the link is soon to be broken. Also the next optimal route to the destination node will be elected before the breakage of any actual route´s link.
