QoS enabled mobility support for mesh networks

Existing solutions for building wireless mesh networks suffer from reduced efficiency. This is due to lack of reliable self-configuration procedures that can dynamically adapt to varying network conditions, lack of efficient and scalable end-to-end quality of service (QoS) support, and lack of generalized and seamless mobility support. Therefore, ensuring a certain level of QoS to mobile users is one of the most crucial challenges, and it is clearly one of the major inhibitors to the commercial success of mesh networks. In this paper, we present a heuristic service classification approach and a correspondent traffic classification algorithm for handling the multimedia traffic at the network and the application layer, in order to better characterize the traffic. The preliminary simulation results show that the approach is able to classify a large part of the traffic and, consequently, to handle it appropriately. This is confirmed by the encouraging preliminary results where the worst case is managed fairly in comparison to the average case.
