Collision-free beacon scheduling mechanisms for IEEE 802.15.4/Zigbee cluster-tr...
Koubâa, Anis; Alves, Mário; Attia, Melek; Nieuwenhuyse, Anneleen VanThe recently standardized IEEE 802.15.4/Zigbee protocol stack offers great potentials for ubiquitous and pervasive computing, namely for Wireless Sensor Networks (WSNs). However, there are still some open and ambiguous issues that turn its practical use a challenging task. One of those issues is how to build a synchronized multi-hop cluster-tree network, which is quite suitable for QoS support in WSNs. In fact,...
On the use of the ZigBee protocol for wireless sensor networks
Nieuwenhuyse, Anneleen Van; Alves, Mário; Koubâa, AnisThis project was developed within the ART-WiSe framework of the IPP-HURRAY group (http://www.hurray.isep.ipp.pt), at the Polytechnic Institute of Porto (http://www.ipp.pt). The ART-WiSe – Architecture for Real-Time communications in Wireless Sensor networks – framework (http://www.hurray.isep.ipp.pt/art-wise) aims at providing new communication architectures and mechanisms to improve the timing performance of W...
