Résumé: This paper describes a prototype low-power wireless link designed for embedding into everyday objects. After a brief description of the hardware platform, we discuss protocols for discovery and long-term rendezvous, contrasting our approach with master-based approaches. The protocols are presented as examples drawn from a larger family of interoperable protocols which may be important to cover the broad range of applications for this sort of network. We then describe some of the applications built using PEN, and add some observations on spectrum costs, and future designs.
