Path Selection: Reliability Service Curve Measurement to Enhance QOS in MANETs

In Mobile Ad hoc Networks (MANETs) the mobility of a node is unpredictable and the mobility is considered as one of the characteristics of a wireless network. A fundamental issue arising inMANETs is the selection of optimal path between any two nodes. A method that has been advocated to improve routing efficiency is to select the most stable path so as to reduce the latency and the overhead due to route reconstruction. In this paper, we proposed Reliability aware Service Curve for Path Selection (RSCPS) which is designed to improve the QOS through node stability, amount of data to be transmitted and required bandwidth to send the data. Thus this scheme enhances the existing end to end path reliability.
