IEEE 802.15. 4 is the de facto standard for Wireless Sensor Networks (WSNs) that outlines
the specifications of the PHY layer and MAC sub-layer in these networks. The MAC protocol …

The IEEE 802.15. 4 standard is a widely adopted standard for low power wireless personal
area networks. It defines several medium access control layer functionalities including …

Body area wireless sensor networks (BANs) are a key component to the ubiquitous
healthcare revolution and perhaps one of its most challenging elements from a …

The IEEE 802.15. 4 protocol offers great potential for industrial wireless sensor networks,

Cluster scheduling and collision avoidance are crucial issues in large-scale cluster-tree
Wireless Sensor Networks (WSNs). This paper presents a methodology that provides a Time …

We consider the problem of running RPL on top of the IEEE 802.15. 4 MAC layer-the two
layers operate over two different structures, a directed acyclic graph in the case of RPL and …

Wireless body area networks (WBANs) represent one of the most promising approaches for
improving the quality of life, allowing remote patient monitoring and other healthcare …

Abstract Time Slotted Channel Hop** (TSCH) Medium Access Control (MAC) is a key
feature of the IEEE 802.15. 4 standard, aimed at accommodating the requirements of …

Abstract Abstract Wireless sensor networks (WSNs) require an extremely energy-efficient
design. As sensor nodes have limited power sources, the problem of autonomy is crucial …
