Broadcast Polling in IEEE 802.16 Networks with Average-Buffered Subscriber Stations

Chandan Singh Ujarari, Arun Kumar Pal

Abstract: We proposed a model to analyze the performance of the contention based services via broadcast polling in unsaturated IEEE 802.16 networks with channel errors. Subscriber station with finite buffer capacity K can be treated as a M/G/1/K queue. Service time can be calculated by the back-off process of broadcast polling. Using this model, the normalized network throughput, Average-Buffered size and the distribution of the packet delay are derived. For performance estimation of best effort or contention-based non-real time polling services this proposed analytical model is used. Additionally, we show that the model gives good approximations for network performance with a more realistic bursty arrival process at light load, while providing conservative performance measures at medium and high loads.
