A powerful and cost effective home security system based on GSM communication network and wireless communication module CC1100 is proposed for anti-theft, fireproofing, waterproofing, anti-gas leak and remote appliance control. The system uses STC89C516 microcontroller as the core and real-timely detects the home environment through a variety of sensors. The dual detections are utilized to reduce the false alarm rate and enhance system reliability and interference immunity. The wireless data transmission is adopted between the main controller and sensor nodes, which does not require a lot of wiring. The bidirection communication between the main controller and the mobile terminal is realized by the GSM networks. Once detecting suspicious activities, the system sends an alarm message to the host’s mobile phone. The user can remotely query the home security status and control the home appliance by the GSM module. The communication is assured within the GSM coverage area, and the distance is unlimited. The GSM short message alarm overcomes the hidden troubles of vulnerable damage and no alarm when calling in the fixed telephone dialing. The interaction interface is optimized. The user can modify the passwords, change the target phone number, alter the upper and lower limits of alarm, query the alarm recording and deploy/cancel defense via the LCD and keyboard. The buttons are installed for help in case of emergencies. The test results show that the system can real-timely monitor and remotely query the home environment, control the appliances and initiatively send alarm messages in case of accidents. The system possesses full function, high reliability, low false alarm rate, strong expansion, friendly user interface and low cost. The application space is very broad.

Synchronization Protocol

ZigBee technology is more and more used in complex and bad industrial monitoring and control environment. At the same time, ZigBee nodes are usually powered by batteries, so prolonging the working time and reducing the power consumption of the nodes is very important. If the wireless nodes can turn into sleep mode in spare time of communication, it will further reduce the node power consumption. But in sleep period, the node can't communication with other node, we need to synchronous awaken and dormancy, so precise time synchronization for wireless sensor network application is particularly important. This paper will apply FTSP algorithm in the ZigBee network and realize the network time synchronization. At the same time, it doesn't increase power consumption of the network.

In this paper we present the details of methodology pursued in implementation of an HMI and Demo Temperature Monitoring application for wireless sensor-based distributed control systems. The application of WSN for a temperature monitoring and control is composed of a number of sensor nodes (motes) with a networking capability that can be deployed for monitoring and control purposes. The temperature is measured in the real time by the sensor boards that sample and send the data to the monitoring computer through a base station or gateway. This paper proposes how such monitoring system can be setup emphasizing on the aspects of low cost, energy-efficient, easy ad-hoc installation and easy handling and maintenance. This paper focuses on the overall potential of wireless sensor nodes and networking in industrial applications. A specific case study is given for the measurement of temperature (with thermistor or thermocouple), humidity, light and the health of the WSN. The focus was not on these four types of measurements and analysis but rather on the design of a communication protocol and building of an HMI software for monitoring. So, a set of system design requirements are developed that covered the use of the wireless platforms, the design of sensor network, the capabilities for remote data access and management, the connection between the WSN and an HMI software designed with MATLAB.

Schools are amongst the most densely occupied indoor areas and at the same time children and young adults are the most vulnerable group with respect to adverse health effects as a result of poor environmental conditions. Health, performance and well-being of pupils crucially depend on indoor environmental quality (IEQ) of which air quality and thermal comfort are central pillars. This makes the monitoring and control of environmental parameters in classes important. At the same time most school buildings do neither feature automated, intelligent heating, ventilation, and air conditioning (HVAC) systems nor suitable IEQ monitoring systems. In this contribution, we therefore investigate the capabilities of a novel wireless gas sensor network to determine carbon dioxide concentrations, along with temperature and humidity. The use of a photoacoustic detector enables the construction of long-term stable, miniaturized, LED-based non-dispersive infrared absorption spectrometers without the use of a reference channel. The data of the sensor nodes is transmitted via a Z-Wave protocol to a central gateway, which in turn sends the data to a web-based platform for online analysis. The results show that it is difficult to maintain adequate IEQ levels in class rooms even when ventilating frequently and that individual monitoring and control of rooms is necessary to combine energy savings and good IEQ.

The design, monitoring, and control of photovoltaic (PV) systems are complex tasks that are often handled together, and they are made even more difficult by introducing features such as real-time, sensor-based operation, wireless communication, and multiple sensor nodes. This paper proposes an integrated approach to handle these tasks, in order to achieve a system efficient in tracking the maximum power and injecting the energy from the PV modules to the grid in the correct way. Control is performed by means of an adaptive Lyapunov maximum power point tracking (MPPT) algorithm for the DC/DC converters and a proportional integral (PI) control for the inverters, which are applied to the system using low latency wireless technology. The system solution exploits a low-cost wireless multi-sensor architecture installed in each DC/DC converter and in each inverter and equipped with voltage, current, irradiance, and temperature sensors. A host node provides effective control, management, and coordination of two relatively independent wireless sensor systems. Experimental validation shows that the controllers ensure maximum power transfer to the grid, injecting low harmonic distortion current, thus guaranteeing the robustness and stability of the system. The results verified that the MPPT efficiency is over 99%, even under perturbations and using wireless communication. Moreover, the converters’ efficiency remains high, i.e., for the DC/DC converter a mean value of 95.5% and for the inverter 93.3%.

The Purpose of this paper is to present one of the various wireless technologies currently available for industrial monitoring and control. Applications of wireless data transmission are universal. In industrial automation, the benefits of adopting wireless technologies in eliminating the needs for cables in hard to reach areas within the plant, increasing data availability and quality and monitoring and controlling remote assets, that otherwise were inaccessible. Radio frequency identification (RFID) technology is commonly used for object or animal identification and tracking. This article explores the feasibility of its use in a rapid solution to wireless real time monitoring of industry. A prototype system for wireless industrial monitoring and control was developed using a commercially available 12.5 GHZ RFID passive tags. Various parameters are sensed by respective sensors (Slaves), which are then monitored by low power, high performance, 8bit AVR microcontroller. Monitored signals are then sent to the RFID tag or transponder unit, hence the smart feature of the sensor. A receiving unit (Interrogator) emits an electromagnetic field which when detected by passive RFID tag causes it to transfer sensor information (data stored in memory) to the interrogator. Interrogator detects these parameters and sends them to the data collection PC (Master Unit). The architecture of the developed wireless sensor prototype allows for additional RFID tags (Slave Units) to be integrated into it without changes to the sensor designs. Design also provides means to update operating and monitoring parameters as well as sensors/RF link specific firmware modules ‘over - the - air’.

The growth of information technology and networking solutions encouraged the deployment of WBSN. It supports the monitoring and control of human conditions towards various issues. However, the security of data transmission and routing plays vital role and to achieve this, different algorithms has been identified. But, the earlier methods are does not produce expected QoS (Quality of Service) parameters. To improve the performance of routing, a novel trust aware light weight routing algorithm (RCP-TLSR (Reputation Completion Privacy Preservation-TLSR) has been proposed. The sensors of wireless body network discover the available routes between the source and destination. The selection of route and the sensor node has been identified according to the RCP measure which has been computed according to the reputation, completion and privacy preservation values. By choosing the routes according to the values of RCP, the method achieves higher performance in routing. On the other side, the data security has been enforced by block level encryption technique which is understandable for the concern sensor nodes. The method improves the performance in security and routing highly.
