The R2 low-power messaging and rendezvous layer
J. N. Weatherall · 2000
Recent advances in microprocessor and wireless technologies have created scope for a new class of device --- the tetherless computer. Tetherless computers encompass not only those devices traditionally regarded as computers but also other electronic household devices. Tetherless computing may even extend, as will be illustrated, to networking non-electronic home items. The R2-Layer provides a simple yet flexible low-power rendezvous and messaging interface suitable for tetherless devices.
