Delay analysis of IEEE 802.16 wireless metropolitan area network

Upper Bound on Overall Delay in Wireless Broadband Networks with Non Real-Time Traffic

“…It accounts for the restrictions of the system model and was previously used in [7], [16], [14] and [17]. According to [24] we set the typical simulation parameters and summarize them in Table 1.…”

“…The analytical model enables the extension for the case of the noisy channel. Finally, the proposed analytical model could be modified to account also for the unicast polling of the SSs incorporating the models of [16] and [17].…”

“…The above summary implies that contention-based polling is the most widespread reservation mechanism in IEEE 802.16. Moreover, it is more difficult to analyze it due to its randomized nature in comparison to the analysis of the contention-free mechanism [16], [17]. Below we formulate a set of assumptions and detail the joint model to account for both the reservation and the scheduling stages.…”

“…16 QoS mechanisms is addressed by numerous research papers. In particular, the so-called bandwidth reservation stage is often considered, at which a network user can reserve a portion of the channel resources.…”

“…According to IEEE 802. 16 protocol the BEB algorithm works with broadcast and multicast polling mechanisms (see [7] for details). The performance evaluation of broadcast polling was studied in [8].…”
