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.
