ADAPTIVE MULTI-CONSTRAINED QOS ROUTING IN MANET

The increasing demand for multimedia applications over MANET expects good QoS over packet delivery that can be provided only if QoS constraints are considered while routing the packets. The QoS metric to be considered in routing will be different for different applications. The challenge here is to identify and prioritize the QoS metrics to be considered for routing under various scenarios. MANET characteristics are previewed under the TCP/IP protocol stack parameter and impact on QoS metrics is analysed with Rough Set Theory. Adaptive Multiconstrained Quality of Service routing is proposed in consideration of dynamically adaptive multi-constrained QoS metrics. The AMQoS takes input from different layers of TCP/IP to understand the scenario on which packets are delivered. RST based decision rules are applied at the destination to filter out Route REQuest message. The results of AMQoS are compared against Priority Aware-DSR and Dynamic Source Routing.
