Performance enhancement of Dynamic Source Routing using simulated annealing in Mobile Ad hoc Networks

A Mobile Ad hoc NETwork (MANET) consists of a collection of mobile nodes. As MANETs are gaining popularity day-by-day, new developments in the area of real time and multimedia applications are rising as well. Such applications require Quality of Service (QoS) evolving in terms of the constraints such as bandwidth, end-to-end delay, jitter and energy. QoS provisioning for MANET can be achieved over different layers starting from the physical layer up to the application layer. This paper mainly looks at the problem of QoS provisioning in the perception of network layer. This paper proposes a QoS aware Dynamic Source Routing (DSR) Protocol using Simulated Annealing called SADSR Simulation results show that the proposed protocol has a better performance than DSR in terms of end-to-end delay, packet delivery ratio and throughput.
