Multimedia Transmission in Wireless Local Area Networks Environment (Greek – Hungarian cooperation)PERSON IN CHARGE: Merakos LazarosFUNDED BY: General Secreteriat of Research and Technology (GSRT) START DATE: 01/06/2004 END DATE: 31/05/2006 DESCRIPTION: In order to build the Information Society efficiently before the end of this decade, infocom services have to be delivered to customers anywhere and at anytime. Wireless Local Area Networks (WLANS) form a solid basis for this endeavour in low mobility local areas. As the use of Wireless LANs (WLANs) becomes more and more popular, so the demand of mobile users for more advanced services with Quality of Service (QoS) through WLANs increases. WLANs provide an easy, cheap and efficient way for mobile users to access remote services while at home, hot-spots, or company premises. A key issue is the design of an efficient QoS traffic handling mechanism that will be adapted to the particular characteristics of WLANs both in centralised or ad-hoc operation mode and will provide adequate QoS level to mobile users, using the advanced capabilities of 802.11e. The 802.11e standard, although complete, does not include the description of a traffic-scheduling algorithm, as this is out of its scope, leaving enough space for research in this area. The basic objective of this project is first to study the existing traffic scheduling algorithms for WLANs, and then develop and evaluate a novel scheduling mechanism for 802.11e that will incorporate the good features of the existing algorithms.
