presented were carefully reviewed and selected from 116 submissions. The
research contributions in this proceedings span many aspects of sensor
systems, including energy efficient mechanisms, tracking and
surveillance, activity recognition, simulation, query optimization,
network coding, localization, application development, data and code
dissemination.
