In this paper, we propose a novel end-to-end resource allocation approach for wireless mesh networks with quality-of-service (QoS) assurance. By introducing additional interference tolerability to each multimedia flow, our proposed approach is shown effective in fostering frequency reuse and increasing the number of multimedia flows supported in the system, outperforming its conventional resource...
Wireless mesh network has recently emerged as a promising technology for next-generation wireless network. Many important applications, such as audio/video conferencing, require multicast communication with quality-of-service (QoS) guarantee. In this paper, QoS multicast routing in wireless mesh networks are investigated. The paper studies TDMA-based timeslot allocation, and presents an effective...
This paper proposes a tabu search (TS) based optimization approach to search a minimum-interference multicast tree which satisfies the end-to-end delay constraint and optimizes the usage of the scarce radio network resource in wireless mesh networks. The path-oriented encoding method is adopted and each candidate solution is represented by a tree data structure (i.e., a set of paths). Since we expect...
Real-time applications such as multimedia applications have high requirements on bandwidth, delay, jitter etc, which requires WMN (Wireless Mesh Networks) to support QoS. QoS routing is crucial to provide QoS. This paper focuses on QoS routing with bandwidth constraint in multi-radio multi-channel WMN, and proposes a new multi-metric and a QoS routing protocol MMQR. The routing metric has two advantages...
This paper presents a decentralised cross-layer dynamic power control (DDPC) scheme for wireless mesh networks (WMNs). A general cross-layer occupation measure (COM) based on transmission scheduling probability (TSP) and power control policy (PCP) model is proposed. Depending on the network traffic application and multiple transmission activity (MTA), each user adjusts its power dynamically so as...
