Wireless sensor home automation networks based upon Sun SPOT

This paper aims to develop a simple wireless sensor home automation network (WSHAN). The WSHAN is implemented using two different specialised motes, i.e, collector and interface motes. The environmental data is sampled and broadcast by collector motes, and the data is received by interface motes and host. Interface motes can forward data to external systems, i.e., climate control, light control and alarm systems, while the host can save received environmental data for further use. Six testbeds are defined to verify the accuracy and performance of the proposed WSHAN. The results show that the selected sensors are deemed to be accurate enough for an WSHAN. Even though the development kit only includes two physical Sun SPOTs (Small Programmable Object Technology), it is possible to develop a working WSHAN. A combination of the physical and virtual Sun SPOTs provide enough motes for the WSHAN to cover a small house.
