Abstract

To improve data transmission robustness in the Wi-Fi Mesh standard, a deterministic channel access method was added to the basic random access method, which enabled the stations to get a contention-free access in the previously reserved time intervals. This mechanism can be conveniently used for transmission of the real-time multimedia streams which require quality-of-service support. However, the packet transmission in the reserved time intervals is affected by random noise and interference, and the time-consuming reservation procedure does not allow one to change on-the-fly the amount of reserved channel resources. A method for dynamic channel reservation which takes into account these aspects of the deterministic channel access mechanism and meets the quality-of-service requirements was proposed.
