“…The RSSI DAAM from [15] was also implemented to provide some comparisons with our method, and the name of RSSI DAAM is shortened as RSSI in the remaining text. Figure 7 shows the number of orphan nodes in the DAAM, TDMAA, and RSSI results, using various network parameter configurations in the uneven node distribution setup.…”

“…To the best of our knowledge, only [15] focused on the tree formation instead of tree adjustment. In [15], three mechanisms, 2DAAM (2 layer DAAM), LDAAM (Location aware DAAM), and (RSSI DAAM) received signal strength indicator DAAM, were proposed for address assignment and, among the tree mechanisms, RSSI DAAM which uses the received signal strength to calculate the distance between two nodes has good performance with least cost and thus is the most recommended mechanism by the authors. Although RSSI DAAM showed better performance than the original DAAM, a scheduling approach complying with ZigBee is missing.…”

The rise of the Internet of Things promotes adopting wireless sensor networks (WSNs) in daily life. In WSNs, the ZigBee standard has gradually become the dominant communication protocol. ZigBee supports various network topologies, including tree structures. Regarding the address assignment of the tree topology, a distributed address assignment mechanism (DAAM) is specified by the ZigBee standard. Using DAAM yields a simple tree routing method; however, network parameter constraints cause the unpreventable orphan problem. Therefore, an innovative address contention approach was proposed based on a time-division multiplexing address assignment (TDMAA) mechanism, which utilizes the ZigBee beacon intervals for address contention. TDMAA outperforms conventional DAAMs in uneven node distributions, sometimes assigning 20% more addresses.
