WiWi: Deterministic and Fault Tolerant Wireless Communication Over a Strip of Pervasive Devices

This paper describes the wireless wire (WiWi) architecture and the protocol performing efficient wireless communication along a strip of pervasive devices, with short- range transmission capabilities. The system is synchronous and shows deterministic properties in terms of throughput and latency. Fault tolerance is also guaranteed by a simple but robust backup algorithm that organizes pervasive devices in clusters, achieving both reliability and energy saving capabilities. With low cost and extremely simple devices, WiWi builds up a kind of "wire-like" dielectric link that is reliable and suitable for many interesting applications.
