Abstract :
In this paper, mixed voice and data packet traffic handling schemes are presented in a wireless multimedia communication environment. Three different schemes are provided with analysis and simulation for comparison on the blocking probability and delay characteristics as performance measures. Analytical models such as a bivariate Markov process are provided and extensive simulation experiments are carried out to investigate the impact of major parameters on the system performance. These reveal that mixed priority schemes for delay sensitive data outperform error-sensitive data with queueing. Also, an optimal queue size as well as the optimal number of reserved channels for handoff delay-sensitive data are given for various traffic conditions
