With the rapid advances in IoT technologies, the role of IoT gateways becomes even more important. Therefore, improving the reliability, availability and serviceability (RAS) of IoT gateways is crucial. Nowadays, Linux is widely adopted for core enterprise systems not only because it is a free operating system but also because it offers advantages in regards to operational stability. With many Linux...
This paper presents a multi-layer distributed performance management model for Internet of Things (IoT) as a service for caregivers. Performance monitoring and control of IoT devices and services are vital functions for e-health systems. Cloud-based IoT systems with centralized data centers further underline the need for distributed management. The main contribution of this paper is a model and prototype...
A unidirectional security gateway is a network system in which data can travel in only one direction. Therefore, the system are used in protecting the safety and reliability of various critical infrastructures. Most of all, it has to be deployed with send and receive transceivers disconnected for one direction to ensure information security. In this paper, we introduce a unidirectional security gateway...
In this paper, an online working condition monitoring system is designed to early warn environmental quality in manufacturing industry. It is very crucial to provide real time and accurate data for staffs, stakeholders and control center to monitor factory air quality at working place. By uploading the all collected data on internet, the environmental condition can be monitored in real time by users...
A novel secure architecture for sensor networks that make use of the LoRaWAN (Long-Range Wide Area Network) protocol specification is proposed in this paper. The paper analyses potential security threats and provides the protection mechanisms and security recommendations to enable protected data transmission and to prevent unauthorized access and data loss in LoRaWAN sensor networks.
With the continuous progress of rural construction, the problem of rural drinking water pollution is increasingly prominent. In view of water pollution, a design of rural drinking water monitoring system based on wireless sensor networks is proposed that nodes take STM32 as the core chip and WLK01L39 as well as its peripheral circuits are used as wireless communication modules and Beidou S1216 is...
Traffic light congestion normally occurs in urban areas where the number of vehicles is too many on the road. This problem drives the need for innovation and provide efficient solutions regardless this problem. Smart system that will monitor the congestion level at the traffic light will be a new option to replace the old system which is not practical anymore. Implementing internet of thinking (IoT)...
In this paper, we present a new loT-based health monitoring approach in which collected medical sensor data is sent to an analysis module via low-cost, low-power and secure communication links provided by a LoRaWAN network infrastructure. We mainly focus on monitoring blood pressure, glucose and temperature in rural areas where cellular network coverage is either absent or does not allow data transmission...
Internet of Things (IoT) services are increasingly deployed at the edge to access and control Things. The execution of such services needs to be monitored to provide information for security, service contract, and system operation management. Although different techniques have been proposed for deploying and executing IoT services in IoT gateways and edge servers, there is a lack of generic policy...
Zambia has faced economic challenges since the beginning of 2015. The economy has come under strain in 2015 due to climate change. As a result, the water levels in the main source of electricity, the Kariba Dam, have dropped. This has caused a critical power deficit. This problem has negatively affected the economy and has further resulted in reduced GDP for the country. Solar energy is a possible...
On functional requirements of atmospheric particle monitoring system, this paper designs a distributed atmospheric particle monitoring system. The proposed system consists of a data acquisition network, embedded gateways, a database server and remote monitoring terminals. The data acquisition network consists of mobile data acquisition nodes and router nodes distributed in monitoring areas which are...
PerfMon is a prototype implementation of a real-time performance management method for sensor data communication in assisted living applications. It is implemented in accordance with the specification for GATT services in Bluetooth low energy (BLE). PerfMon provides a tool for real-time performance monitoring and control for caregivers and service providers. Test results from monitoring and control...
Having seamless Internet connection is highly desirable for wireless sensor network (WSN). IPv6 offers the most promising solution to deal with the large quantity of nodes or "things". This demonstration presents a versatile research and development (R&D) or prototyping platform, on which we implement generic hardware and software framework for sensing/monitoring as well as remote control...
Cloud Storage is one of the hot research topic, now a day's many enterprises or even individuals have involved in cloud computing related technologies and the various organizations are developing cloud storage systems some of them are open source and freely available to the client for example: GlusterFS, Ceph, LVM, ZFS, Swift, Sheepdog, Kinetic etc. Many researchers have worked on these types of open...
This article studies problems related to the control of inbound traffic in a given country. Its objective is to give a visibility on the inbound traffic. With this intention, we suggest an architecture allowing controlling the incoming calls effectively. The proof of the good working order of our system was made by the use of the servers linked with activation of CDR. Then, a monitoring interface...
Agricultural sector has been facing great challenges in order to feed the increasing number of population living in the world. In the future, it will be very difficult to rely on traditional farming to produce food. Some researchers and industry experts have begun developing smart farming by utilizing information technology. This paper presents the conceptual model and system design for decision support...
With the implementation of the national internet plus strategy, more and more devices enjoy the chances of getting access to internet. But for devices like sensors whose resources are quite limited, it is a tremendous challenge to link to the Internet by using the traditional communication methods. Taking the memory size, computing power and energy consumption of the resource-constrained device into...
With more and more attention to solar energy, the monitoring of solar cells and energy storage systems is gradually important. This research uses the Raspberry Pi as the core processor to develop the mobile monitoring system. Our system can be divided as three parts, the first part is to sense the information including photovoltaic panel image and battery indexes such as voltage, current, SOC (state...
Generally, the project reveals about the semantic web services based implementation of home appliances into ZigBee coordinators network. Certain studies have been conducted based on the same project. All those studies provided a static environment which was not applicable for dynamic system interactions. In all the previous papers only conventional web services are being used. We have an architecture...
Traditional database information and IoT real time data are now evolving to unified paradigms in whose accessing diverse data endpoints can be challenging due to interoperability problems that emerge when instant data are monitored and collected in typical database scenarios. In this paper, a new model is proposed to link persistent data with instantaneous information using publish-subscribe networks...
