Abstract(s)
The ART-WiSe (Architecture for Real-Time communications in
Wireless Sensor Networks) framework aims at the design of new
communication architectures and mechanisms for time-sensitive
Wireless Sensor Networks (WSNs). We adopted a two-tiered
architecture where an overlay Wireless Local Area Network (Tier 2)
serves as a backbone for a WSN (Tier 1), relying on existing standard
communication protocols and commercial-off-the-shell (COTS)
technologies – IEEE 802.15.4/ZigBee for Tier 1 and IEEE 802.11 for
Tier 2. In this line, a test-bed application is being developed for
assessing, validating and demonstrating the ART-WiSe architecture.
A pursuit-evasion application was chosen since it fulfils a number of
requirements, namely it is feasible and appealing and imposes some
stress to the architecture in terms of timeliness. To develop the testbed
based on the previously referred technologies, an implementation
of the IEEE 8021.5.4/ZigBee protocols is being carried out, since
there is no open source available to the community. This paper
highlights some relevant aspects of the ART-WiSe architecture,
provides some intuition on the protocol stack implementation and
presents a general view over the envisaged test-bed application.
