QoS Support in 802.11 based Mesh Networks

Present QoS work only addresses isolated components of a comprehensive solution for end-to-end QoS support. The project re-uses existing components where appropriate, focusing on the explicit linkages between the various layers: MAC, routing and signaling, QoS models and end-to-end QoS frameworks. The resulting technology is ultimately aimed at "non-office" work environments including, for example, subways, construction sites, dockyards, highways and forestry operations.

This project involves many partners linked together through the National Capital Institute of Telecommunications (NCIT).

The project focuses on the explicit linkages between the various layers: MAC, routing and signaling, QoS models and end-to-end QoS frameworks. The open-source software Optimized Link State Routing Protocol (OLSR) that is being developed and implemented for Mobile Ad hoc Networks (MANET) by CRC researchers will be used in this project. CRC will provide enhancements to OLSR to provide cost-based routing based on optimal bandwidth. Research will include cross-layer protocol interactions between the MAC and network layer and improved QoS.
