In densely deployed WLAN environment, the WLAN can experience severe inter-cell interference which may cause a considerable performance degradation. In order to mitigate this issue, we propose a centralized channel allocation scheme considering the uncontrolled neighboring access points. The proposed scheme estimates the channel utilization based on the received beacon signals without any help from...
Due to the license-exempt nature of the cognitive radio (CR), multiple CR networks may operate (coexist) on the same channel. In this paper, we first discuss some techniques for self-coexistence of CR local and personal area networks, where the self-coexistence means the coexistence of homogeneous CR networks using the same PHY/MAC protocol. Then, we propose a self-coexistence etiquette for the ECMA...
We propose QoS-aware mesh deterministic access opportunities (MDAOPs) assignment algorithm for the IEEE 802.11s wireless mesh networks (WMNs). The WMNs can benefit from the mesh deterministic access (MDA) in terms of guaranteeing the QoS of the delay bounded traffic, mitigating the exposed node problem, and providing the fairness among best effort traffic flows. However, it is not considered that...
