Abstract
802.11e is a new supplement to the family of 802.11 standards, which aims at providing QoS to voice and other streaming services. Nodes are assured transmission opportunities within their delay bounds in the contention free period (CFP). A beacon is used to mark the start of a CFP. Any delay in the issue of the beacon would adversely affect the timely delivery of time-sensitive traffic. In this paper, we propose a scheme that prevents the delays in the beacon issue, which might be caused due to nodes operating in the contention period, transmitting MAC service data units beyond super frame boundaries. Our beacon management scheme not only assures a timely beacon issue enhancing the delay bound guarantees but also maintains the throughput. Simulations were conducted to analyze the performance of the proposed scheme. The results demonstrate that when timely transmission of QoS bound traffic is achieved by preventing a late beacon issue, the average length of super-frames is maintained and results in increased number of super frames over time.
