Abstract:
The paper presents an approach of applying DCF77 time radio signals to provide a clock with global time in sensor
networks based on TinyOS. Some nodes containing DCF77 receiver hardware reliably decode time signals even if these are
distorted to some extent. The clock with global time is provided by compensating clock drift. Time is distributed in
the network with a protocol generating timestamps on the MAC layer.

Abstract:
This paper proposes and analyses the idea of replacing professional mobile radio for airport ground handlers by VoIP systems based on WLAN. The proposed communication scheme is adjusted to business processes at airports. It provides push-to-talk unicast and group messages (determined by business tasks or location) with priorities, encrypted transmission, and mailboxes. The resulting architecture and proof-of-concept prototype consists of a server and software clients reusing already installed hardware and WLAN infrastructure, and uses peer-to-peer RDP voice streams. Bandwidth considerations estimate a maximum of 72 concurrent streams per access point on WLAN for IEEE 802.11g (54 Mbit/s) and 13 streams for IEEE 802.11b (11 Mbit/s), enhanced with a factor 3 to 5 if IEEE 802.11e is used as quality of service support.

Abstract:
The paper analyses potentials, challenges, and applications of using rewritable, stationary RFID tags for marking routes for autonomous vehicles in manufacturing environments. This approach promises to be flexible, robust, and inexpensive. Two algorithms are proposed also considering additional sensors.
