Fair Wireless Access Control with Error Compensation Based on Retry Count

Fairness in the number of effective opportunities for wireless access between the uplink and downlink and that between stations cannot be achieved in wireless packet communications such as wireless LANs due to the packet error caused by packet collisions or received power degradation. In this paper, we propose fair wireless access control with error compensation (FWAC/EC) to achieve fairness over an unstable link. The key features of the proposal are release delay control and packet compensation control. The point of the release delay control is to control the waiting time for attempting a subsequent transmission after an ongoing transmission. The point of the packet compensation control is continuous transmission based on the number of retries. Simulation results show that FWAC/EC achieves fairness in the number of effective opportunities for wireless access between the uplink and downlink and that between stations over an unstable link.
