Web service and a smartphone are used for the client system to monitor and control the home. The remainder of this paper is organized as follows. In Section 2, IEEE 802.15.4 and ZigBee specifications are discussed as background technologies. Section 3 describes design issues of remote monitoring and controlling systems. Next, implementation results are include in Section 4. Finally, we conclude this paper in Section 5.2. Background Technologies2.1. IEEE 802.15.4 IEEE 802.15 is a working throng for the standardization of WPAN ( tuner Personal Area Network). IEEE 802.15.4 is one of the seven task groups which are included in it. The set-back edition of the 802.15.4 standard was released in May 2003. IEEE 802.15.4 specifies the physical layer (PHY) and media access control (MAC) for low-rate WPAN. WPANs are used to convey information over relatively short distances. It focuses on low-cost, low-speed ubiquitous communication between devices. irrelevant wireless topical anaesthetic area networks (WLANs), connections effected via WPANs involve little or no infrastructure. This feature allows small, power-efficient, low-cost solutions to be implemented for a wide race of devices. The basic framework conceives a 10-meter communication range with a transfer rate of 250 kbit/s.Important features include real-time suitability by reservation of guaranteed time slots, collision avoidance through CSMA/CA and integrated support for secure communications. Devices overly include power management functions such as link quality and energy detection 6. Several standardized and trademarked network layer protocols run over 802.15.4-based networks, including IEEE 802.15.5, ZigBee, 6LoWPAN, Wireless HART, and ISA100.11a. Potential application areas include the following sensors, actuators, synergistic toys, remote control, industry networks, home automation and so on. 2.2. ZigBee ZigBee is a standards-based technology that addresses the unique requirements of most remote monitoring and control and sensory network applications. ZigBee builds upon the physical layer and medium access control delimit in IEEE 802.15.4 for low-rate WPANs.The specification go es on to complete the standard by adding four main components network layer, application layer, ZigBee device objects (ZDOs) and manufacturer designated application objects which allow for customization and favor total integration. The initial markets for ZigBee included Consumer Electronics, aptitude Management and Efficiency, Health Care, Home Automation, Telecommunication Services, Building Automation, and Industrial Automation. The core ZigBee specifications define smart, costeffective and energy-efficient mesh networks. It is a self-configuring, self-healing system of redundant, low-cost, very low-power nodes. ZigBee is available as two feature sets, ZigBee PRO and ZigBee. Both feature sets define how the ZigBee mesh networks operate 7.2.3. Home Network Technologies A home network is a residential topical anesthetic area network (LAN) for communication between digital devices typically deployed in the home, usually a small number of personal computers and accessories, mobile computing devices, mobile phones, digital TVs, PDAs and so on. An important function is the manduction of Internet access, often a broadband service provisioned by fiber-to-the-home or via Cable Internet access, digital Subscriber Line (DSL) or mobile broadband by Internet service providers (ISPs).In a broader sense, it includes software and services for integration and operation of information appliances in addition to fit out or wireless network devices. Home networking technologies roll in the hay be classified into two kinds wired and wireless. The telephone, power-line, Ethernet and IEEE 1394 exist as wired home network technologies. As wireless home network technologies, wireless LAN, HomeRF, HyperLAN, Bluetooth, UWB (Ultra Wide Band) and ZigBee are representative. Since wireless networking solutions based on the spread of mobile devices have emerged they behind be applied to home networks also.3. inclination of Remote Monitoring and Controlling SystemThis section deals with the design of remote monitoring and controlling systems. To design a system, we considered a home automation network. The system architecture is presented in paradigm 1. contour 1. System Architecture The system consists of a real-time home monitoring sub-system and a light control subsystem. A home waiter with a home camera caters for home status through video to client. It also works as a home gateway to provide interoperability between the heterogeneous ZigBee and Internet and local and remote control over the homes light devices through the light control sub-system. A client give the axe access the home master of ceremonies through a web service or smartphone. The client can monitor home status through a real-time monitoring sub-system and control the lights through the3.1. Real-time Monitoring Sub-system The real-time monitoring sub-system captures images of the area of the home to be monitored and serves the client who accesses the server through the web or a smartpho ne.Figure 2. Operation Processes of Real-time Monitoring Sub-system Figure 2 shows the operation process of the real-time monitoring sub-system. The server finds a video device and captures images. Then, it generates captured data and transforms the data format for RTP communication. After that, it generates the session manager and streams media data to the client. A client using the web or a smartphone generates the session manager and connects to the server. Then, it receives media data and displays the video. In this way, the client can monitor the in-home status in real-time. 3.2. Light Control Sub-system Light control sub-system is composed of a server which works as a gateway, ZigBee coordinator, end-device, switch node and a light as shown in Figure 3.The operation of the sub-system is as follows. A client program maintains a user interface which contains an on/off control panel. A server which works as a gateway receives control commands from the client and relays the comm and to the ZigBee coordinator through the RS-232C serial communication. The coordinator relays the control command which is received form the server to the end device through RF communication. The end device receives the command from the coordinator and controls the port of the switch node. The switch node controls the switch of the light.ZigBee based remote controlling can be applied in several ways. In this paper, we considered a simple light control and follow it for a remote control sub-system.4. Implementation ResultsIn this section we discuss implementation results of a real-time remote monitoring and controlling system. The server contains a web-cam and the monitoring and controlling programs are implemented using Java. Web-based remote monitoring with video capture, data encoding and RTP communication are implemented using JMF (Java Media Framework) which is a multimedia extension API of Java. A client using web service can access the server after(prenominal) user authen tication. Of the ZigBee networks, we use two Chipcon CC2420DB evaluation boards with CC2420s (IEEE 802.15.4 radios) accompanying Z-Stack 8, 9, 10. One is configured as a coordinator and the other is configured as an end-device. When the coordinator starts, it initializes all internal ports and waits for control commands from the home server. If the home server sends a control command to the coordinator through the serial communication, the coordinator receives the command and sends it directly to the end-device through RF communication. The end device receives the control command from the coordinator and controls the switch node.Figure 4. Implementation Result using Web Service Figure 4 shows the implementation results using web service. A client can access the server after user log-in. The client can monitor the rooms status and control the lights. In the figure, the client turns off the light. The implementation results using a smartphone are shown in figure 5. The client program is implemented on the android platform.Figure 5. Implementation Result using Smartphone As shown in the results, a client can monitor the in-home status in real-time and send light control commands using the control departure on the smartphone.5.
