An Interference-Aware Admission Control Design for Wireless Mesh Networks

With the increasing popularity of wireless mesh networks (WMNs), the demand for multimedia services encompassing VoIP, multimedia streaming and interactive gaming is increasing rapidly. The realtime services require stringent Quality of Service (QoS) guarantees for effective communication, as compared to best-effort services (for e.g, file transfer) that are tolerant to changes in bandwidth and delay. While a lot of research has dealt with providing QoS support for real-time services in traditional wired networks, the shared and broadcast nature of the wireless medium necessitates the design of new solutions for multi-hop wireless networks. In multi-hop wireless networks, unlike wired networks, the communication from one node will consume the bandwidth of the neighboring nodes and hence the shared bandwidth can be easily overutilized. Therefore, to provide an acceptable level of QoS for the realtime services, it is necessary to control the utilization of the shared bandwidth. In this p...
