ContextNet is a scalable middleware for the Internet of Mobile Things. It is composed of: a) SDDL, a suite of cloud-based services for communication and processing, interacting through DDS, and b) Mobile-Hub, a smartphone-based component that discovers, connects with and acts as an internet proxy for Bluetooth-enabled smart objects. ContextNet also provides Complex Event Processing (CEP) engines for sensor data stream processing both in SDDL and the Mobile-Hub, on smartphones, at the IoT edges. It also features HORYS, a parallel NoSQL-based service for registering the (opportunistic) encounters between M-Hubs and mobile smart things (sensors or beacons).
