In the context of CALIPSO, we focus on three types of smart objects and applications: (1) Smart Toys, (2) Smart City, and (3) Critical Infrastructures. Smart Toy products belong to the mass and consumer industry market. Smart City products belong to a mix of governmental, municipal, and citizen markets. Critical Infrastructure products belong to specific industrial security markets. All three have in common that they usually support a single application and use proprietary protocols and wireless technologies optimized for reduced energy consumption.
