A Reliable Path Selection Mechanism to Enhance QoS in MANET Routing Protocols

Abstract — MANET is a collection of mobile nodes forming a dynamic autonomous system without using any physical infrastructure. Mobility of mobile nodes leads to dynamic change in topology of the network. The topological change in MANET leads to Path failure which degrades the network performance. A fundamental issue arising in MANETs is the selection of optimal path between any two nodes. In this paper multipath between source and destination are determined; reliability measurement is done towards node and path to predict the risk on the specified path. The proposed RSCPS Reliability Measurement is associated with Service Curve Measurement (RSCPS) to enhance the QoS through node stability, amount of data to be transmitted and bandwidth required to send the data
