Link Break Prediction Routing Protocols a Survey

Abstract

A Mobile Ad-hoc Network (MANET) is an infrastructure less and decentralized network which needs a robust routing protocol. With the development of the MANET applications, more importance is given to Quality of Service (QoS) routing strategy. However mobility of the nodes leads to frequent link failures and packet losses affecting the QoS performance of the protocol. The new route rediscoveries increases the overhead and latency. Performance of the MANETs can be improved if the link breakage prediction mechanism is integrated into the routing protocol that predicts the link failure before its real occurring. This leads to increase in link availability time. A no. of protocols related to link breakage prediction in mobile ad hoc networks have been proposed in the literature. This paper presents a survey of some of the link break prediction routing protocols along with their strengths and weaknesses.
