“…To deal with clock-drifts, a follower must reserve a guard time before the expected beacon transmission. A typical clock drift is equal to 10 ls per second [24] (10 ppm), and the beacon transmission lasts about 100 ls. Finally, following a new parent costs a node 0.18% more energy.…”

“…The LABS [29] mechanism is similar to MeshMAC [27] in the initialization work, however, LABS can allocate a higher number of time slots on demand. In [30], the authors used a dedicated period called Beacon Only Period (BOP) that is used for beacon transmissions at the beginning of the superframe structure. The PAN coordinator defines the maximum number of slots in the BOP.…”

“…Therefore, in the pure dynamic approach, schedulability will be greater than k n si , i.e., higher than MeshMAC. In [30], schedulability depends upon the number of slots in the BOP ( d max ), which is pre-defined by the PANC. Choosing a higher d max value do not necessarily increase the schedulability as it decreases the slots available for data transmission.…”

The IEEE 802.15.4 standard is one of the most widely used link layer technology for building Internet of Things. It specifies several physical layer options and MAC layer for meeting low-power and low-rate requirements of devices deployed in a network of IoT. The standard also specifies a synchronization scheme for devices connected in a star topology, operating in beacon-enabled (BE) mode using periodic beacons. The BE mode facilitates synchronization among devices for data transmission and is suitable for large networks to establish low duty-cycles. Absence of a such a scheme for a cluster-tree network has confined its application only to non-beacon mode. The challenge here is to schedule beacon frame transmissions of multiple devices in a non-overlapping manner to avoid beacon collisions. This paper tackles the problem of synchronization by proposing localized beacon synchronization (LBS) scheme, a distributed technique for beacon scheduling in cluster-tree network topologies. LBS uses 2-hop information and association order to compute beacon transmission offsets that better utilize the available time slots, incur fewer transmissions, and is highly scalable. Further, we analytically show that the schedulability of the proposed scheme is higher compared to other related schemes. In addition, we also address the important issue of resynchronization that has been ignored in all of the prior works. The proposed re-synchronization mechanisms consider the interdependencies between synchronization and duty-cycling schemes and are shown to significantly lower the synchronization overhead when synchronization among devices is lost.

“…The TD implementation prevents the use of broadcast messages between FFDs, which negatively affects the operation principle of the AODV protocol and excludes the creation of multi-hop routing paths. On the contrary, in the BOP approach, beacon broadcasters (FFDs) are forced to be deployed at precise locations to ensure global network synchronization [ 75 ]. These locations might have no power asset to control.…”

The Smart Grid (SG) is conceived as the evolution of the current electrical grid representing a big leap in terms of efficiency, reliability and flexibility compared to today's electrical network. To achieve this goal, the Wireless Sensor Networks (WSNs) are considered by the scientific/engineering community to be one of the most suitable technologies to apply SG technology to due to their low-cost, collaborative and long-standing nature. However, the SG has posed significant challenges to utility operators—mainly very harsh radio propagation conditions and the lack of appropriate systems to empower WSN devices—making most of the commercial widespread solutions inadequate. In this context, and as a main contribution, we have designed a comprehensive ad-hoc WSN-based solution for the Smart Grid (SENSED-SG) that focuses on specific implementations of the MAC, the network and the application layers to attain maximum performance and to successfully deal with any arising hurdles. Our approach has been exhaustively evaluated by computer simulations and mathematical analysis, as well as validation within real test-beds deployed in controlled environments. In particular, these test-beds cover two of the main scenarios found in a SG; on one hand, an indoor electrical substation environment, implemented in a High Voltage AC/DC laboratory, and, on the other hand, an outdoor case, deployed in the Transmission and Distribution segment of a power grid. The results obtained show that SENSED-SG performs better and is more suitable for the Smart Grid than the popular ZigBee WSN approach.
