The global demand for Internet access services has increased at a notable rate in recent years. The quality of service (QoS) of several real time multimedia applications has become a crucial research topic. One of the challenges to achieve QoS requirements is to determine how to allocate system bandwidth to various applications with the respect of their QoS(More)
Quality of service (QoS) is still a crucial issue that deals with the IEEE 802.16 network performance. Scheduling is a key component of the MAC IEEE 802.16 layer which ensures QoS for different service classes. In this paper, we give a detailed simulation study for some scheduling algorithms by evaluating their performance in order to support the QoS(More)
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 handoff call(More)
