Real-Time Communications over Cluster-Tree Sensor Networks with Mobile Sink Behaviour
Ref: HURRAY-TR-080801 Publication Date: 25 to 27, Aug, 2008Abstract:
Modelling the fundamental performance limits of
Wireless Sensor Networks (WSNs) is of paramount
importance to understand the behaviour of WSN under
worst-case conditions and to make the appropriate design
choices. In that direction, this paper contributes with a
methodology for modelling cluster-tree WSNs with a
mobile sink. We propose closed-form recurrent
expressions for computing the worst-case end-to-end
delays, buffering and bandwidth requirements across any
source-destination path in the cluster-tree assuming error
free channel. We show how to apply our theoretical results
to the specific case of IEEE 802.15.4/ZigBee WSNs.
Finally, we demonstrate the validity and analyze the
accuracy of our methodology through a comprehensive
experimental study, therefore validating the theoretical
results through experimentation.
