When Nanjing IOT Wireless Sensor Networks Meet the Cloud Tech

A Wireless Sensor Network (WSN) consists of a large number of low-cost, low-power, multifunctional and resource-constrained sensor nodes with each sensor node consisting of sensing, data processing, and communicating components; these nodes can operate unattended for long durations. Sensor networks are designed with the flexibility to withstand harsh environmental conditions. These are networks of wireless interconnected smart devices designed and deployed to retrieve sensor data of interest from their host environments. Sensor nodes perform measurements of some physical phenomena, collect and process data, communicate with other peers or a central information processing unit, the sink. These nodes are capable of sensing various phenomena, such as Pressure, Temperature, Humidity, Position, Velocity, Acceleration, Force, Vibration, Proximity, Motion, Biochemical agents, etc. They are capable of processing textual, voice and video data making them very useful.
According to the National Institute of Standards and Technology (NIST), Cloud Computing (CC) is an innovative technological paradigm that provides convenient, on-demand network access to a shared pool of configurable computing resources (for example, sensors) that can be rapidly provisioned and released with minimal management effort or service provider interaction.
Cloud Computing provides several benefits such as on-demand self-service, broad network access, resource pooling (location independence), rapid elasticity, measured service, massive scale, homogeneity, virtualization, resilient computing, low cost software, geographic distribution, service orientation and advanced security.
The integration of these two key technologies (WSNs and CC) provides us with a robust and scalable infrastructure for several applications such as the Smart Grid. This novel approach allows for the efficient management of millions of smart meters or sensors and other energy management systems. This infrastructure also provides the tools necessary for collecting, disseminating and storing real-time sensor data from geographically disparate sensors. The Cloud components provide a foundation for securing and providing user access to the software, middleware and hardware resources.
Nanjing IOT Sensor Technology is the Chinese leading supplier for IOT devices products and solutions. It keeps sustainable innovation based on customers' needs to have determined the industry leader in several major areas such as sensors, IOT modules, mobile IOT and cloud computing etc. The company has become leader of IOT time with the comprehensive advantages in such areas as objects perception and data transfer etc. Till now, the products and solutions have been applicated in several focused IOT demonstraion projects, which have made us become important technical support force for IOT city construction all over the country. The company have good wish to make people sense the true world, using various types of sensors to enable people from different area and industry to get information more directly,freely and equally and eliminate information bias. For dealing with the increasingly severe climate change and all kinds of geological disasters, by our advanced low carbon solution, the company helps customers use the green way to create the optimal social, economic and environmental benefit, and to realize longterm maintenance of human development and security.
