Abstract:
Current solutions for network mobility support in wireless mesh networks lack Quality of Service (QoS) capabilities. Thus, they are not well suited for supporting services with QoS requirements (e.g., Voice over IP or Video on Demand). WiOptiMo is a solution, originally designed for seamless handoff management in the Internet, that was adapted for seamless internetworking in wireless mesh networks. In this paper, we show how its basic infrastructure was modified in order to meet the QoS expectations of mobile users running heterogeneous applications on a wireless mesh network. Specifically, QoS support is provided by aggregating application traffic flows with the same characteristics to limit overhead and by relaying compressed aggregated flows to the appropriate mobility provider. We experimentally evaluate the performance of our aggregation scheme and demonstrate that link utilization is optimized and QoS is improved.
