Real time multimedia applications become an important part of Internet traffic and require a guaranteed quality of services. Call Admission Control (CAC) is a key element in the provision of guaranteed (QoS) in wireless networks. An adaptive algorithm is proposed in this paper. The QoS measures studied are new call blocking probability and handotT call probability. We describe and we compare several adaptive admission control schemes in terms of performance and complexity. Also, maintaining the blocking probability below a certain value (threshold) adaptively to QoS requirements is the common purpose of the proposed CAC algorithm. The bandwidth resources allocated to handotT calls and new calls change dynamically in order to maintain the threshold of the call blocking probabilities.

Symmetrical applications are multimedia applications that require both uplink and downlink connectivity. The demands of symmetrical applications are expected to grow rapidly in the future but there is still no resource management that can efficiently support symmetrical applications over heterogeneous services in IEEE 802.16 system. In this paper, we propose a resource management scheme that can support symmetrical applications along with heterogeneous services. The proposed scheme comprises of a joint uplink and downlink allocation, dynamic control system and bandwidth recycling framework. Simulation studies show that the proposed scheme outperforms asymmetrical scheme in terms of throughput, delay and packet loss. The proposed scheme also achieves similar performance gains in more complex environment.

“…As for the AC schemes proposed for IEEE 802.16 BWA networks, the authors of [5,6] did not consider the handoff situation, which is a crucial characteristic of IEEE 802.16e. The authors of [7][8][9][10] took the handoff requirements in to account regardless of the channel condition. For the general AC schemes proposed in [4,[11][12][13][14][15][16][17][18], the time-variant channel conditions were not considered either.…”

This article proposes an integrated framework for adaptive QoS provision in IEEE 802.16e broadband wireless access networks based on cross-layer design. On one hand, an efficient admission control (AC) algorithm is proposed along with a semi-reservation scheme to guarantee the connection-level QoS. First, to guarantee the service continuity for handoff connections and resource efficiency, our semi-reservation scheme considers both users' handoff probability and average resource consumption together, which effectively avoids resource overreservation and insufficient reservation. For AC, a new/handoff connection is accepted only when the target cell has enough resource to afford both instantaneous and average resource consumption to meet the average source rate request. On the other hand, a joint resource allocation and packet scheduling scheme is designed to provide packet-level QoS guarantee in term of "QoS rate", which can ensure fairness for the services with identical priority level in case of bandwidth shortage. Particularly, an enhanced bandwidth request scheme is designed to reduce unnecessary BR delay and redundant signaling overhead caused by the existing one in IEEE 802.16e, which further improves the packet-level QoS performance and resource efficiency for uplink transmission. Simulation results show that the proposed approach not only balances the tradeoff among connection blocking rate, connection dropping rate, and connection failure rate, but also achieves low mean packet dropping rate (PDR), small deviation of PDR, and low QoS outage rate. Moreover, high resource efficiency is ensured.
