Architecture of QoS Guaranteed Joint Design of Node-Disjoint Multipath Routing and Subcarrier Allocation in OFDMA Mesh Networks
Dapeng Zhang, LAURIE G. CUTHBERT · 2009
Wireless Mesh Networks based on OFDMA and the Node-Disjoint Multipath Routing Protocol (NDMR) can provide practical high-speed broadband and robust transmission. In this paper, NDMR, a practical protocol in WMN is studied. it reduces routing overhead and achieves multiple node-disjoint routing paths. Also, the OFDMA based WMN and its subcarrier allocation problem is investigated. A novel QoS guaranteed dynamic subcarrier allocation based on NDMR is introduced.
