摘要:Abstract One of the most important aspects a effecting the overall QoS performance of hybrid mobile ad hoc networks is the efficient discovery of Internet gateways. So many previous papers addressed the problem of interconnecting Mobile Ad Hoc Networks (MANET) to the Internet, via one or more attachment points called gateways. The protocol employed to discover available gateways and set up routes to the Internet should not incur in a big overhead, due to the insufficient resources of ad hoc networks. However, previous works do not meet this requirement either when the number of traffic sources or available gateways increases. In our work, we develop a QoS based analysis of Proxied Adaptive gateway discovery scheme which dynamically adapts its behavior depending on the number of active traffic sources which are in the MANET. This approach employs intermediate nodes which make use of available local information (proxies) to further reduce the control overhead, and provide a high packet delivery ratio using NS2 Network Simulator.
