Analysis of Broadband Cellular Networks with Variable Bit-rate Connections

As multimedia applications are becoming reality in wireless/mobile environments new analytical modelling techniques are required that can handle the variable bit-rate nature of such applications. This paper presents an analytical method to examine channel occupancy and blocking properties of radio base stations serving VBR connections. This method is based on an approximation that makes possible the computation of above properties despite the huge complexity of the problem. Two service disciplines of handling calls arriving with too big bandwidth demand are analysed.
