A Smart and Contemporary Home Security System using 802.15.4 standard

Smart wireless home security technique is one of the emerging technologies for intelligent building surveillance. Many wireless technologies like Bluetooth and Wi-Fi have been used in this regard. In this paper we have proposed a Smart and Contemporary Home security system using low cost, low power Zigbee (802.15.4) standard. The Zigbee uses multi-hop communication for data transfer. The architecture consists of many Zigbee modules that have been configured as end devices, routers and one coordinator respectively. The end devices communicate with each other and with the coordinator using the intermediate nodes (routers). This multi-hop architecture provides it an unlimited range of communication thus giving it an edge over the other wireless technologies. The Hardware has been implemented successfully using XBEE Pro series1 (XBP24-AWI-001) radios for communication, Passive Infrared sensor (DYP-ME003) and Magnetic Reed Switch (ORD221) based door sensor that have been tested for validation.
