Improve Home Sensory and Controlling Network with Network Based on IEEE-802.15.4 and Cloud Computing

This paper aims at presenting a method to lower the power consumption of the wireless home sensory and controlling systems. To realize it, we put forward a new network layer called ¿Pithur¿, which is based on IEEE 802.15.4 and can extend the battery life to 7~9 times than that of a Zigbee network, at the cost of lower performance and longer latency time. Also we lowered the power consumption of the home gateway by moving the computing task to an Internet server with the cloud computing technology. We have already built up a smart home system with the two improvements mentioned above, and experiments showed that the power consumption of the system is highly reduced compared with the ones based on the Zigbee network.
