Abstract—IEEE 802.15.4 protocol provides a low data rate and low energy consumption solution for wireless sensor networks which are the basis of the Internet of Things. However, the variable topology of wireless networks requires high flexibility and robustness to be achieved by network configuration mechanisms. In this paper, a Scalable Distributed Address Assignment Mechanism (SDAAM) is designed, which adopts adaptive approach to handle the variability present in the topology of wireless networks. In the proposed approach, every newly arrived node can be correctly configured regardless of the current network topology so that it can communicate with other nodes within the same network. Another important advantage of SDAAM is its handling of unexpected events which may arise due to migration or departure of nodes in the network. Detailed description about SDAAM is presented and its effectiveness and high flexibility is demonstrated based on the simulation program.
