Software Defined Networking (SDN) is a developing networking paradigm that advocates a complete overhaul of the conventional networking. SDN decouples the control logic from the data forwarding functionality; which traditionally are coupled on the network device. The coupling stifles innovation and evolution because the network often becomes rigid. Software Defined Wireless Sensor Networks (SDWSN)...
Wireless sensor network (WSN) TestBed design challenges can be divided into three main sub-categories: architectural, hardware and software. By considering all these challenges, an optimal solution was found and EDI TestBed created. In this paper, a method, which solves software related problems in large scale WSN TestBed, such as how to distribute computational resources, control all of the TestBed...
The fault rate of on-load tap-changer (OLTC) has always been in a high level, and that is exactly the primary reason of transformer faults. As a result, an on-line detection method of OLTC was proposed. The embedded platform and wireless sensor network (WSN) technology was introduced into the on-line detection system. WSN was used to obtain OLTC status information. The embedded platform software,...
This paper presents the use of wireless sensor network (WSN) technologies in a newly growing application space in industrial Internet or industry 4.0. This application space focuses on factory automation and field process management that we call Machine Area Network (MAN) applications. We describe key requirements, major technical challenges and how hardware and software can be combined to address...

Emerging environmental related problems have greater impact on technical, scientific, social and economical fields, which is why this issue needs attention. On a global scale this issue are being sort out using satellite based instruments. This paper discusses a monitoring system which gives information about environmental conditions on a more local level, the implementation area are categorize by...
This paper presents a ZigBee-enabled RFID along with the capabilities of WSN for an environmental monitoring system. The wireless technology used for communication in the project aims to overcome wiring or cabling problems within a building or structure that has space constraint or dense wiring for data transfer. There are two different analog sensors that are included in the design while the ADC...
Information and communication technologies are an important driver for supply chain performance. This paper analyses the ICTs' relative requirements for efficient supply chain management. Logistical systems in a supply chain, can integrate a combination of compatible information access, sensing and communication technologies. Such as RFID, WSN, GSM, GPRS, Wi-fi. The existing Applications of ICTs within...
Horticulture industry in India is beginning to see the technological drive and that leads to the low production of greenhouse. In general equipment cost of drip irrigation, motors, solenoid valves etc. Which may cost upto Rs. 4 lakh, many not be affordable for greenhouse owners. Keep this in view, we propose an innovative implementation of software aspects of WSN (Wireless Sensor Networking) for monitoring...

The sensor node signal interface is the channel for sensor connecting to sensor node. Therefore, in order to verify the conformance between sensor network signal interface and signal interface standard, the design and implementation of WSN signal interface conformance test system based on web wsa presented. The test content included the signal interface description file, signal type supported by interface,...
A Solar-Powered Sensor Module (SPSM) that uses low-cost capacitors as energy buffers to power wireless sensor motes was investigated. Compared to batteries or super capacitors, SPSM is particularly suitable for light-weight tasks since it buffers limited energy and powers up periodically. With our method, the energy charging time can be shortened to about 100 ms for a maximum power point tracking...
The recent years realize a progressive transition where fixed computing reached maturity and the mobility age started to thrive. Nowadays, another transition from the mobility age to the “Internet of Everything” (IoE) is taking place. In the IoE vision, several types of quotidian objects will be able to communicate over the Internet. As a result, it is expected that within a decade, IoE will have...
The fast development of WSN (Wireless Sensor Network) provide the solution to indoor localization application. To which, the position accuracy become the essential problem need to solve. At the same time the cost of software development also impede the indoor application. This paper introduces in detail the composition of the whole system and the design of localization algorithm based on RSSI. Through...
Obtaining hundreds of sensor nodes to experiment new algorithms on Wireless Sensor Network (WSN) in real testbed is costly and time consuming. Simulation environment can reduce these costs though it may not produce exactly same results as real testbeds. There is many kind of simulations available for WSN such as Cooja and Tossim. None of these simulation environments provides an all-in-one solution...
Wireless Sensor Network (WSN) deployment appears like a crucial step for network Quality of Service (QoS). In this context a real conception has to be planed before a deployment on the studied area. Actually researches use a simple and regular Area of Deployment (AoD) representation and do not allow interactive interface for a non programmer. Our approach tries to provide a tool to elaborate a strategy...
We propose an Open Sensor Platform, based on Open System Architecture design, for the integration of mobile phone (MP) and sensors. This platform utilizes commercial off-the-shelf (COTS) available hardware and software tools, thereby eliminating the need for custom-designed sensor's integration boards. The design involves Data Acquisition (DAQ) device, attached with Host PC, providing an interface...
This paper describes the study about parking spaces detection in indoor environments, implementing a WSN (Wireless Sensor Network) based on Zigbee technology. Our study focuses on the analysis of the received power when a vehicle is parked or not, by monitoring the RSSI (Received Signal Strength Indicator) field defined in the MAC layer as the IEEE 802.15.4 describes. We focus in the analysis of three...
The majority of wireless sensor networks are built on bespoke platforms, that is, custom designed and built hardware with a light weight software stack. There are a number of advantages to this approach. First, the ability to closely match and minimise the resource requirements (e.g., power consumption and communications protocols) to those that are suitable for the intended deployment. Second, as...
