Efficient Voice Communications over IEEE802.11 WLANs Using Improved PCF Procedures

The Third International Network Conference - INC 2002, July 2002.

Abstract: This paper presents a new dynamically adaptable polling scheme for efficient support of voice communications over different IEEE802.11 networks. The proposed Cyclic Shift and Station Removal polling scheme is implemented only on the Access Point of each Basic Service Set without requiring any modification on the existing access protocol. The analytical approach that models the proposed polling scheme, uses a discrete-time Markov chain and proves that the CSSR polling scheme, when silence detection is used at the mobile terminals, improves the performance of the IEEE802.11 Point Coordination Function significantly.
