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 shortrange 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.
