Higher layer synchronization in an ECMA-368 Ultra Wideband network

An algorithm for implementing higher layer synchronization in ECMA-368 networks is being developed within the framework of the EUWB research and development project. In this paper, we adapt three synchronization algorithms used in wireless sensor networks to suit an Ultra Wideband (UWB) network and evaluate their performance in order to determine the best algorithm for a video streaming application scenario. We also propose some extensions to the ECMA-368 standard that would facilitate the implementation of these algorithms. For these purposes, we have simulated a UWB beacon group in OPNET. We observe that the algorithms that correct for clock drift are better suited for implementation in a UWB network.
