The present invention relates to a ubiquitous sensor network. In particular, a plurality of sensors installed in existing residential complexes, apartments, shopping malls, and u-City buildings detect intrusions or fires from a Zigbee-based sensor network to map an accident site. The present invention relates to a system and method for intrusion detection and fire detection using a ubiquitous sensor network to cooperatively co-operate with residents before they arrive at a security company or a fire station by displaying an alarm, generating an alarm, and notifying an SMS message.

In general, the Ubiquitous Sensor Network (USN) uses RFID sensors or ZigBee sensor nodes to detect intrusions in the home in the home network, building automation, gas safety monitoring using gas sensors, and location recognition in industrial sites. It can be applied to precipitation measurement, medical system or scientific field by service, logistics management, and intelligent environment monitoring.

The ZigBee protocol is a compound word of 'Zigzag' and 'Bee' which means bees. It is a compound word meaning that everything moves around and communicates like a bee chasing flowers. It is enacted as an IEEE 802.15.4 standard that supports.

When using the ZigBee protocol, the sensor node installs an embedded operating system (eg Tiny OS) for the sensor network and provides multi-hop routing technology. In addition, the sensor node may be an illumination sensor, a temperature sensor, a humidity sensor, an infrared sensor, a gas sensor, an ultrasonic sensor, an acceleration sensor, a bio sensor, and a home automation sensor.

ZigBee is one of the IEEE 802.15.4 standards for providing near field communication. It provides technology for near field communication and ubiquitous computing within 30 meters of homes, offices, and buildings, and includes sensor network, home automation, and building automation ( Example: Used in building heating ventilation systems (HVAC) and monitoring systems.

Unlike IEEE 802.1 or IEEE 802.15, ZigBee is suitable for the ultra-small, low-power, low-cost market, and transmits data at a transmission speed of 250 kbps within a radius of 30 m. With a mesh network structure, ZigBee uses about 255 devices in one wireless network. Devices can be connected and multi-hop routing is supported.

The RF module for sensor network nodes uses IEEE 802.15.4 / ZigBee, while ZigBee features low cost and low power, based on the standardized PHY / MAC layer of IEEE 802.15.4. Used for wireless communications standardizing applications.

1 is a diagram illustrating a layer of a conventional sensor network protocol.

The ZigBee stack structure is based on the OSI 7 layer model, and the IEEE 802.15.4 standard defines two layers, the physical layer (PHY layer) and the link layer (MAC sub-layer), and the ZigBee Alliance The ZigBee Alliance defines a framework for the network layer and application support layer.

The Zigbee PHY layer, defined in IEEE 802.15.4, operates over three frequency ranges: 868 MHz, 915 MHz, and 2.4 GHz. 868 MHz is used in Europe, 915 MHz is used in countries such as the United States and Australia, and 2.4 GHz is used worldwide.

In addition, the ZigBee MAC Sub-layer, defined in IEEE 802.15.4, accesses the wireless channel using the CSMA-CA mechanism, and provides the ZigBee Coordinator with devices of sensor nodes in the Personal Network Area (PAN). It periodically transmits a beacon frame, provides synchronization management, and a reliable transmission mechanism.

The ZigBee Network (NWK) layer provides management functions for joining or leaving new sensor nodes to the sensor network, providing security for transmission frames, routing to nodes that want to send frames, and so on. It is responsible for the management functions for neighboring devices. The network layer of the ZigBee Coordinator is responsible for initiating a new network and also assigning addresses to newly joined devices.

The ZigBee application layer consists of an APS sub-layer, ZDO (ZigBee Drive Object), and application objects defined by the manufacturer. The Zigbee Application Layer manages the bindings between devices based on the services and requests provided by the device, maintains a binding table, and is responsible for message forwarding between the bound devices.

Zigbee Drive Objects (ZDOs) are responsible for defining the device's role in the network, handling binding requests between network devices, and establishing security relationships between devices. In addition, the Zigbee Drive Object (ZDO) provides the ability to discover devices in the network and determine the application services they provide.

In ZigBee, the network layer (NWK) supports star and mesh topologies. In a star topology, a single device called the ZigBee Coordinator manages and controls all end devices in the sensor network and provides communication capabilities.

In a mesh topology, the Zigbee coordinator is network initiated, and the network may be extended using the Zigbee router.

ZigBee Network Layer provides Data Service and Management Service to provide application layer and service interface. Network Layer Data Entity (NLDE) provides data transmission service via SAP (NLDE-SAP) associated with NLDE and management service via SAP (NLME-SAP) associated with NLME. . The network layer management entity (NLME) uses NLDE for some management tasks and maintains a database of Network Information Base (NIB) objects.

In ZigBee, the routing algorithm assigns network addresses in a hierarchical manner, hierarchical routing to determine whether the frame destination is its descendants or higher ancestors in the hierarchy by simply comparing the addresses, and broadcasting. Routing routes are discovered using RREQ and Unicast RREP messages, and sensor nodes use table-driven routing, which maintains a routing table for the route found.

The ZigBee application layer is composed of an application framework, a ZigBee device object (ZDO), and an application support sublayer.

The Application Support Sublayer (APS) transfers the service of an application PDU (Packet Data Unit) between two or more devices in the same network. The Application Support Sublayer (APSDE: APS Data Entity) and APS Information Base (AIB) A service is provided by an application layer service management entity (ASPME) that maintains a database of managed objects and provides services for binding and discovering devices.

ZigBee Device Objects (ZDOs) provide control and management of application objects through their public interface. The ZigBee Device Object (ZDO) connects the interface through the lower part of the ZigBee protocol stack and Endpoint0 of APSDE-SAP for data and APSME-SAP control messages. The public interface provides management of device discovery, binding, and security within the application framework layer of the Zigbee protocol stack. Device discovery is used in a unicast or broadcast manner using an address of a ZigBee Coordinator or ZigBee Router.

These ZigBee technologies can be applied to a variety of ubiquitous computing environments such as intelligent home networks, building automation, and industrial device automation, logistics, environmental monitoring, telematics, and military.
