In this paper we present the RISE (RIverside SEnsor) platform, a novel system design for embedded sensors built around a System-on-Chip device interfaced with a large external storage memory in the form of off-the-shelf SD (Secure Digital) Card. We describe the hardware and software structure of RISE, which supports the standard TinyOS and NesC environment.(More)

Our system follows a mobile-based network-assisted architecture to eliminate the communication overhead and respect user privacy. When a user enters our university campus a smartphone client conducts a single communication with a dedicated server to receive the(More)
