Design and implementation of "kubit" for sensing and control ubiquitous applications

Towards the wide acceptance of ubiquitous networking, practical and deployable ubiquitous applications must be provided in a concrete and easily understandable form to end-users. We designed and implemented ubiquitous nodes, KDDI Ubiquitous Bit (kubit). The highest priority was given to application-oriented design and ease of deployment in a typical home network environment. The kubit quickly detects anything suspicious with built-in sensors, and sends notification of the event via e-mail containing an image to be displayed on a PC or mobile phone, as well as controlling the existing home appliances via a PC or mobile phone or led by the event.
