Abstract

Wireless Mobile Ad-hoc Networks has became vital in terms of Quality of Service (QoS) is aimed at delivering different services provided by the network to end users. Hybrid MANET is essential for wireless infrastructure networks and difficult to set up communication over enormous areas, with the evolution of the Internet. Routing packets for connecting the MANET to Internet, to optimize a path for the gateway discovery is a great challenge and vital concentration has been given to the design of routing protocols to attain better performance over existing protocols. Most of these routing protocols use information accessible during the network layer to route the packets. In this proposal, using Contention aware Adaptive Based routing Protocols, the information at the link layer in addition to the information at the network layer are manipulated. This concept is incorporated with existing protocols like OLSR and QAODV. Those new protocols are named as Contention aware Adaptive Based OLSR (CAB-OLSR) and Contention aware Adaptive Based QAODV (CAB-QAODV) protocols. The simulation results have shown that the proposed protocols improved various QoS metrics for the MANET to Internet connection.
