The IEEE 802.16 standard for broadband wireless access is a low cost solution for Internetaccess in metropolitan and rural areas. Although it defines five service levels to support real-time and bandwidth demanding applications, scheduling mechanisms are not specified in the standard. Due to the wireless channel variability, scheduling mechanisms widely studied for wired networks are not suitable...
In IEEE 802.16e system, most of existing scheduling algorithms focus on the real time services, while few of them have particularly considered the best-effort (BE) service. Since the BE service class is defined for non-realtime traffic with the lowest priority among all 802.16e scheduling services, it corresponds to applications with no specific rate or delay requirement. However, considering the...
IEEE 802.16 standard is proposed for providing high data rate and middle-range access to Internet through wireless access channel. The increasing of data rate, access range, and total number of wireless nodes makes the wireless media access control more difficult and critical. Our objective is to provide a fair and efficient allocation to all the users to satisfy their quality of service. In this...
The following topics were dealt with: wireless sensor networks; MANET; WLAN; IEEE 802.11; MIMO; OFDMA; scheduling; mobility and resource management; Internet; localization; WiMax; coding; OFDM; media streaming; QoS; security; WiMob; cryptographic protocols; ad hoc networks security; broadband wireless access; wireless and mobile computing.
IEEE 802.11 is the WLAN standard for providing moderate to high speed data communication in a short range generally within a building. IEEE 802.16 (WiMAX) is the standard for broadband WMANs which can provide Internet access over a long range outdoor environment susceptible to fading inside buildings. The logical topology to extend the coverage of the broadband WiMAX is to integrate it with WLAN at...
