We present empirical measurements of the packet delivery performance of the latest sensor
platforms: Micaz and Telos motes. In this article, we present observations that have …

Security issues for software systems ultimately concern relationships among social actors
stakeholders, system users, potential attackers-and the software acting on their behalf. We …

The efficacy of data aggregation in sensor networks is a function of the degree of spatial
correlation in the sensed phenomenon. The recent literature has examined a variety of …
