A New Polling - Based Dynamic Slot Assignment Scheme for Broadband Wireless Access Systems
SUMMARY This paper proposes a new polling-based dynamic slot assignment (DSA) scheme. With the rapid progress of wireless access systems, wireless data communication will become more and more attractive. In wireless data communication, an efficient DSA scheme is required to enhance system throughput, since the capacity of radio links is often smaller than that of wired links. A polling-based DS...
متن کاملDistributed contention-free traffic scheduling in IEEE 802.11 multimedia networks
Wireless local area networks are a promising solution to support advanced data services in mobile environments. The IEEE 802.11 wireless LAN standard is emerging as a mature technology to support delay sensitive network services. In order to support these services the standard has proposed the use of a polling scheme; however, existing polling schemes require high communication overheads or suf...
متن کاملAn Opportunistic DRR (O-DRR) Uplink Scheduling Scheme for IEEE 802.16-based Broadband Wireless Networks
We present a novel scheme for uplink scheduling in WiMax networks that attempts to balance worst-case fairness in bandwidth allocation with the delay requirements of traffic, while taking the varying nature of the wireless channel into account. We assume a polling-based mode of operation at the base station ( ), and provide a method of obtaining an optimal polling interval at which the should p...
متن کاملAn Efficient and Fair Polling Scheme for Bluetooth
Bluetooth is a universal radio interface in the 2.45Ghz frequency band, which will enable users to connect a range of small electronic devices. Any two or more Bluetooth-enabled devices that come within range of each other can set up an ad hoc connection, called a piconet. Within a piconet, the unit that establishes the piconet becomes the master and the rest of the units act as slaves. The mas...
متن کاملA Fair and Traffic Dependent Scheduling Algorithm for Bluetooth Scatternets
The Bluetooth specification defines the notion of interconnected piconets, called scatternets, but does not define the actual mechanisms and algorithms necessary to set up and maintain them. The operation of a scatternet requires some Bluetooth units to be interpiconet units (gateways), which need to time-division multiplex their presence among their piconets. This requires a scatternet-schedul...
