Info

• Packet video streaming in wireless ad hoc networks: One characteristic of the ad hoc networks is that there are many paths between the video source and destination. Thus, a mechanism that takes advantage of these multitude of paths is expected to perform better (i.e., in supporting QoS for real-time traffic) than the classical one-path approach. Moreover, rather than selecting a single path at any time to use for a specific connection, a better scheme would be to always distribute the information among multiple paths, possibly with some correlation between the information on the various paths, so as to protect against failure of some subset of the paths. A possible proposed mechanism may consists of four steps: (1) discovery of multiple paths between the source and the destination nodes and evaluation of the correlation in the paths availability; (2) selection of a subset of the paths into an Active Path Set (APS), based on some “goodness” measures (such as the expected reliability of the path, the capacity of the path, the delay and jitter of the path, etc), and a scheme that allows to evaluate these measures for the network paths; (3) a method of coding and spreading the information among the paths (including matching the paths with the specific requirements of a traffic type); (4) a scheme to monitor the APS paths, estimates their QoS parameters, and updates the APS based on the state of the paths and their correlation. • Implementation Issues: Most of our performance evaluations are done using simulation. We plan to implement the core components in real. This can be done by using an open streaming environment such as MPEG4IP Server developed by the multimedia and mobile networking group of the PRiSM laboratory (University of Versailles). This allows us to perform real world experiment in a local area network as well as on the Internet. 158
