QUALITY OF SERVICE AWARE OF CROSS LAYER APPROACH ON ADAPTIVE GATEWAY DISCOVERY SCHEME FOR MOBILE AD HOC NETWORKS

Abstract

The Quality of Service (QoS) providing in Mobile Ad hoc networks has been obtaining increasing importance, specifically Consider the domains of application for networks in disaster environments and defense ventures, QoS is performing level of a service recommended by the network to the consumer. Mobile Ad hoc Networks (MANET) are necessary because of wireless infrastructure network is complicated to setup for providing communication over huge areas, with the initiation of the Internet, requirement for global communication is also becoming an essential requirement for MANETs, Hence; Internet connectivity in MANETs has received considerable attention in the recent years. Routing packets effectively inside and outside a MANET is a challenge and much endeavor has been given to the design of routing protocols to attain higher Packet Delivery Ratio (PDR) over Intra-MANET and Internet-MANET. Though, most of these routing protocols use information obtainable at the network layer to route packets. This study proposed to Contention Aware QoS based Adaptive routing Protocol by manipulating the information gained at the link layer as well as to the information obtainable at the network layer to achieve higher PDR compared to existing protocols, in simulations shown that QoS aware cross layer approach can achieve higher PDR for Internet-MANET traffic.
