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...
Long Term Evolution represents an emerging and promising technology for providing a broadband ubiquitous Internet access. But several aspects have to be considered in order to provide an effective service to users. In particular, in this work, we consider the problem of optimizing the performance of real time downlink communications using a novel two-level scheduling algorithm. The upper level exploits...
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...
The latest tremendous growth of the Internet has opened up a vast market for high-speed broadband data services to the home. Broadband network services have created great opportunities for new multimedia applications at both home and businesses. Data over cable service interface specification (DOCSIS) is the leading standard for data over cable networks. DOCSIS is developed to support IP flows with...
