Technical report TR09-14. We consider the problem of aggregation convergecast scheduling in wireless sensor networks. Aggregation convergecast differs from regular convergecast in that it accommodates transmission dependencies that allow in-network aggregation to be performed. We formulate the...
Technical report TR00-16. A key requirement for the successful deployment of Video-on-Demand (VoD) systems is to maintain both bandwidth efficiency as well as tolerable startup latency. The startup latency is defined as the interval between the point a user \"tunes-in\"' to (starts downloading)...
Technical report TR08-02. We consider the problem of vehicle classification using acoustic signals captured within a sensor network. The sensors perform collaborative decision and/or data fusion in a distributed and energy efficient manner. We present a distributed cluster-based algorithm,...
Technical report TR09-01. Finding the top-k values is an important type of aggregation query in wireless sensor networks. Previous proposals relied on a given underlying logical tree topology for data aggregation/forwarding, but did not pay due attention to the role of such topology. In this...
