We present a new protocol for reliable data transfer in time-critical applications with zero tolerance for data loss in wireless sensor networks which uses less time and fewer messages in comparison to an established protocol PSFQ. Two key features of our protocol are out-of-sequence forwarding of packets with a priority order for sending different types of messages at nodes and delaying the re...

A major challenge of mobile information technology use in time-critical work settings is to balance the temporal impact on the work practice caused by the technology.

We assessed exposure to noise among workers who regularly wear earphones ...
