— This invited paper overviews the low level debug support hardware required for an on-chip predeployment debugging system for sensor networks. The solution provides significant...
Abstract— This paper presents measurements of radio interference using ”Ambient µNode” sensor nodes. We varied distances and frequencies giving us a measure of the amount of...
— In this paper we consider the problem of constructing a coordinate system in a sensor network where location information is not available. To this purpose we introduce the Virt...

Abstract-- We address the problem of batching messages generated at nodes of a sensor network for the purpose of reducing communication energy at the expense of added latency. We f...
We investigate in this paper the anchor selection problem with consideration of anchor location uncertainty, which arises naturally from error propagation problem in successive or...
