The IEEE 802.15. 4 standard is one of the most widely used link layer technology for
building Internet of Things (IoT). It specifies several physical layer options and MAC layer for …

Lack of synchronization mechanism in IEEE 802.15. 4 standard for cluster-tree topology has
restricted its use to non-beacon mode. Initial works in this direction are more centralized in …

The IEEE 802.15. 4 standard provides a synchronization mechanism for devices connected
in a star network topology using beacons. The lack of it in peer-to-peer network topology …

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 …

The recently standardized IEEE 802.15. 4/Zigbee protocol stack offers great potentials for
ubiquitous and pervasive computing, namely for Wireless Sensor Networks (WSNs) …

IEEE 802.15. 4 standard specifies a beacon-enabled mode which provides a
synchronization environment using beacon transmissions. However, this mode is designed …

Abstract While the IEEE 802.15. 4/Zigbee protocol stack is being considered as a promising
technology for low-cost low-power Wireless Sensor Networks (WSNs), several issues in their …

Synchronization is a challenging and important issue for time-sensitive Wireless Sensor
Networks (WSN) since it requires a mutual spatiotemporal coordination between the nodes …

We are witnessing the dawn of a new paradigm in Information and Communication
Technologies (ICT), where large-scale embedded computing systems will interact with the …

The IEEE 802.15. 4/ZigBee standards support the implementation of cluster-tree networks,
which are a suitable topology to deploy wide-scale networks. In this type of topology, an …
