Performance evaluation of Multiple metrics quality of service Routing protocols in mobile Ad hoc networks

Abstract

A Mobile Ad hoc NETwork MANET consists of a collection of mobile nodes They communicate in a multi hop way without a formal infrastructure Owing to the uniqueness such as easy deployment and self organizing ability MANET has shown great potential in several civil and military applications As MANETs are gaining popularity day by day new developments in the area of real time and multimedia applications are increasing as well Such applications require Quality of Service QoS evolving with respect to bandwidth end to end delay jitter energy etc Consequently it becomes necessary for MANETs to have an efficient routing and a QoS mechanism to support new applications QoS provisioning for MANET can be achieved over different layers starting from the physical layer upto the application layer This thesis mainly concentrates on the problem of QoS provisioning in the perception of network layer QoS routing aims at finding a feasible path which satisfies QoS considering bandwidth end to end delay jitter energy etc The existing QoS routing solutions were dealt with any one or two of the QoS parameters like bandwidth or delay or energy or bandwidth and delay Many of the existing QoS routing protocols deal with bandwidth requirement newline newline newline
