Delay Analysis of Wireless Broadband Networks with Non Real-Time Traffic

In this paper, the authors present the analysis of the mean overall packet delay of non real-time traffic in IEEE 802.16-based wireless broadband networks. They consider the case of contention-based bandwidth reservation. The system model accounts for both bandwidth reservation and packet transmission delay components of the overall delay. The queueing analysis is based on the description of the joint content of the outgoing subscriber station buffer and the base station grant buffer. This is achieved by means of a properly chosen bivariate embedded Markov chain. The mean overall packet delay is computed from its equilibrium solution. The analytical approach is verified by means of simulation. The corresponding analytical and simulation results show excellent agreement with each other.
