Inter-Domain Radio Resource Management for Wireless LANs
Yasuhiko Matsunaga, Randy Howard Katz · Kluwer Academic Publishers eBooks · 2006
In this paper, we presented a framework of fair-sharing the radio resources among different administrative domains. Based on the measurement data collected from the WLAN access points and stations, the RRB optimizes and redistributes the radio resources among the domains by dynamic channel compensation, power control, or network-initiated load balancing. To characterize the cell-level workload, we collected statistics from a campus WLAN and derived an empirical two-state Markov model. Using that workload model, we confirmed our proposed schemes by simulating radio resource redistribution between two domains with different traffic demands. Simulation results show each domain’s credit (cross-domain impairment) is kept within an allowable level in the long run by using either channel compensation or load balancing schemes. Thus the fair allocation of radio resources among domains is possible. We also showed that network-initiated load balancing is effective for redistributing radio resources in a short time span.
