Service Differentiation Via Adaptive Gateway Discovery in Ad Hoc Networks Connected to Wired Networks

A gateway discovery mechanism is necessary to allow wireless nodes in an ad hoc network to route their packets towards a fixed network. Real-time applications have quality of service parameters and require a gateway discovery mechanism that helps them to maintain their requirements. Therefore we propose in this work a new adaptive gateway discovery scheme that adjusts the frequency of the gateway advertisements dynamically. This protocol is able to differentiate services between applications and it cooperates with real-time flows to maintain the desired quality of service. Simulation results investigate the performance of the proposed adaptive scheme and show its effectiveness in comparison with the hybrid mechanism in the simulated scenarios.
