Abstract

Abstract

A novel voice / data call admission control algorithm based on call buffer in wireless networks is presented in this paper, which is charactered by dual thresholds with queueing for Variable Bit-Rate Data Traffic call ( DTQ-VBR ). The algorithm gives attention to the VBR character of data traffic and can adapt its service bandwidth through different settings of the thresholds and the call buffer size. Theoretical performance analysis is made by using three dimensions Markovian chain, and it is also shown that compared with DTR-Q and DTBR algorithm, the performances of the presented algorithm such as average channel utility, call dropping probability and block probability can be improved significantly according to a number of simulations.
