| Outline of Final Research Achievements |
To improve the transmission performance of private wireless networks operated in unlicensed radio frequency bands, this research proposes a distributed medium access control protocol that enables centralized radio resource management. In the protocol, private wireless networks existing in the same area form a cooperative group, and the central controller acts as a master to organize the access of associated stations. Once the cooperative group reserves the radio resource, the central controller allocates the reserved radio resources to the stations. Since the central controller dynamically allocates the fine-grained resource blocks to the stations through the opportunistic two-dimensional scheduling based on the channel and traffic conditions of each station, the transmission opportunities can be granted to the appropriate stations. Numerical results confirm that the proposed protocol enhance the throughput while satisfying QoS requirements.
