Broadband Wireless Access (BWA) offers QoS-aware broadband access through a wireless medium, being IEEE 802.16 one of the BWA standards. In it, the Base Station (BS) is responsible of allocating the required bandwidth by the rest of nodes, acting as a central controller. The other nodes, Subscriber Stations (SSs), have to send a bandwidth request to give the BS the knowledge about their needs, taking...
Existing uplink scheduling schemes at subscriber station (SS) in WiMAX suffer from problems like waste of resources and greater access delay for VoIP services. We propose an efficient uplink scheduling scheme to solve above mentioned problems. The SS uses two reserved bits of generic MAC header of IEEE 802.16d to record the voice status of current time unit and informs the base station (BS) without...
Packet and flow scheduling algorithms for WiMAX has been a topic of interest for a long time since the very inception of WiMAX networks. WiMAX offers advantages particularly in terms of Quality of service it offers over a longer range at the MAC level. In our paper, we propose a scheduling scheme that is compatible with 802.16 MAC protocol and can efficiently serve real time bursty traffic with reduced...
In last few years there has been significant growth in the area of wireless communication. Quality of Service (QoS) has become an important consideration for supporting variety of applications that utilize the network resources. These applications include voice over IP, multimedia services, like, video streaming, video conferencing etc. IEEE 802.16/WiMAX is a new network which is designed with quality...
