Versatile Support for Efficient Neighborhood Data Sharingdata in the neighborhood is often substantial. Therefore, we present a general-purpose algorithm for this task that makes use of the broadcast nature of radio transmission to reduce the number of packets. We have integrated this algorithm into ., a programming language extension for data exchange. T

Efficient Routing from Multiple Sources to Multiple Sinks in Wireless Sensor Networksta sources. Recently, however, scenarios with multiple sinks are increasingly being proposed, e.g., to deal with actuator nodes or to support high-level programming abstractions. The resulting . communication makes the existing solutions for single-sink scenarios inefficient..In this paper, we propo

inTrack: High Precision Tracking of Mobile Sensor Nodes, we show that the approach can also be applied to precision tracking of mobile sensor nodes. We introduce inTrack, a cooperative tracking system based on radio-interferometry that features high accuracy, long range and low-power operation. The system utilizes a set of nodes placed at known location

Approximate Initialization of Camera Sensor Networkse that traditional vision-based techniques for calibrating cameras are not directly suitable for low-power sensors deployed in remote locations.We propose approximate techniques to determine the relative locations and orientations of camera sensors without any use of landmarks or positioning technol

Trail: A Distance Sensitive WSN Service for Distributed Object Trackingbjects is required more often and more quickly than that of farther objects. In this paper, we present a wireless sensor network protocol, ., that supports distance sensitive tracking of mobile object by in-network subscribers upon demand. . achieves a . time that is linear in the distance from the
