IEEE 802.15.4 PHY-Schicht

2014
Die PHY-Schicht bildet die Schnittstelle zur Hardware die letztendlich fur das Senden und Empfangen von Daten verantwortlich ist. Hierzu zahlt insbesondere die Daten eines empfangenes Signal interpretieren zu konnen bzw. ein Signal so zu senden, dass es der Empfanger interpretieren kann. Dies ist keine ganz triviale Aufgabe.

Cross-channel interference in IEEE 802.15.4 networks

2008 IEEE International Workshop on Factory Communication Systems, 2008
The growing spread of the IEEE 802.15.4 and ZigBee protocols to support communications in many contexts, such as industrial environments, home and building automation and wireless sensor networks, has led to the deployment of large complex monitoring networks, in which multiple PANs operate in parallel on different channels.

GTS Allocation Strategy for IEEE 802.15.4 WSN

2014 International Conference on IT Convergence and Security (ICITCS), 2014
This paper details about the performance of the GTS allocation mechanism in IEEE 802.15.4. The analysis gives a full understanding of the behavior of the GTS mechanism with regards to Throughput and Wasted Bandwidth due to IFS. The impact of IEEE 802.15.4 parameters on the Wasted Bandwidth of a GTS allocation is analyzed which pave the way for an ...
