Abstract: On the basis of advances in the internet of things (IoT), lots of efforts have been devoted to smart home systems, that aim at providing intelligent and comfort living environment for residents. To construct flexible and robust home networks (HNs) for smart home systems, this paper proposes a novel wireless home networks structure using IEEE 802.15.4 protocol. The proposed approach solves the network address confusion problems which may occur in adjacent HNs in a residential building. In the proposed wireless home network structure, newly arrived network nodes can be correctly configured with unique network addresses. The proposed approach also improves the network robustness by handling unexpected events, caused by migration or departure of nodes within HNs. Simulation results demonstrate that the proposed approach can effectively restore home networks after destructions of sub-networks; and it achieves nearly 80% network address utilisation ratio.
