ART-WiSe - Architecture for Real-Time communication in Wireless Sensor networks

The ART-WiSe (Architecture for Real-Time communication in Wireless Sensor networks) research framework aims at devising new communication architectures and mechanisms in order to improve the Quality-of-Service (QoS) in large-scale distributed embedded systems, such as in Wireless Sensor Networks (WSNs).

Our research differs from others mainly due to the merging of two concerns: 1) to achieve traffic differentiation and time-bounded communications in these large-scale networked resource constrained systems; and 2) to rely on standard communication protocols and commercial-off-the-shelf technologies.

For this purpose, we are pursuing a multiple-tiered communication architecture building on the IEEE 802.15.4/ZigBee protocols for the lower Tier (sensor network) and on the IEEE 802.11 protocol for the higher Tier (backbone). Results attained so far on the use of the ZigBee for WSNs (check our open source toolset) with real-time requirements are quite encouraging, but many challenges are yet to be addressed.
