Technical report TR06-24. Wireless sensor networks have received much attention recently. Given their autonomy, flexibility and large range of functionality, they can be used as an effective and discrete means for monitoring data in many domains. Typically the network autonomy implies a limited...
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...
Technical report TR05-23. Wireless sensor networks are made of autonomous devices that are able to collect information, store it, process it and share it with other devices. Such framework can be used to efficiently query spatiotemporal data, e.g., for monitoring humidity and temperature levels...
