Distributed Interference-Aware Admission Control With Soft Resource Allocation for Hybrid MAC in Wireless Mesh Networks
Supporting Quality of Service (QoS) while fulfilling high efficiency of bandwidth utilization is challenging in wireless mesh networks. To deal with this issue, hybrid Medium Access Control (MAC) protocols are effective candidates because they can achieve QoS support and better resource sharing at the same time. However, in multi-hop communication environments, hybrid MAC protocols suffer from interference and low bandwidth efficiency. To solve these problems, in this paper, the authors propose a Distributed Interference-Aware admission Control Algorithm (DIACA) with soft resource allocation for hybrid MAC protocols suitable for IEEE 802.11 wireless mesh networks; a scheme for providing QoS improvement for Real-Time SessioNs (RTSNs) while enhancing the efficiency of bandwidth utilization.
