— Wireless channels are highly affected by unpredictable factors such as cochannel interference, adjacent channel interference, propagation path loss, shadowing and multipath fading. The un-reliability of media degrades the transmission quality seriously. Forward Error Correction (FEC) schemes are frequently used in wireless environments to reduce the high(More)
This draft describes a specific problem encountered when using RSVP (Resource Reservation Protocol) over optimised routes in MIPv6 (Mobile IP Version 6). The address translation in the MIP's binding cache creates a mismatch between the flow-id of the packets sent from correspondent node to mobile node and the flow-id signalled by RSVP. We discuss several(More)
The growth of the Internet community and the trend towards multimedia services changes the Internet Protocol (IP) suite. Simultaneously, users desire to have a high speed wireless access to the Internet. To meet the increased service and mobility needs the traditional IP protocol has been enhanced with advanced mobility and Quality of Service (QoS)(More)
This paper gives an outline and solutions to the problem of running RSVP signalling in Mobile IP (Mobile Internet Protocol) networks using optimised routing. First, we discuss a basic solution to this problem. By modifying RSVP at mobile and correspondent nodes to become aware of MIPv6 addressing, we provide a simple repair that allows RSVP flows to be(More)
This deliverable explores the need for a Dynamic Channel Allocation (DCA) mechanism in WAND-like systems. In the context of this study, two main approaches are presented: a centralised and a distributed one. The deliverable describes the basic characteristics of both approaches from which possible advantages and disadvantages are extracted. For each(More)
Wireless channels are highly affected by unpredictable factors such as cochannel interference, adjacent channel interference, propagation path loss, shadowing and mul-tipath fading. The unreliability of media degrades the transmission quality seriously. Automatic Repeat reQuest (ARQ) and Forward Error Correction (FEC) schemes are frequently used in wireless(More)
