Wireless sensor network (WSN) consists of a large number of low-cost sensor nodes, low power, multifunctional and resources with each sensor node consisting of sensing, data processing, and communication components; These nodes can operate without supervision for long duration. The sensor network is designed with flexibility to withstand harsh environmental conditions. This is a network of smart-related wireless devices designed and deployed to retrieve interesting sensor data from their host environment. The sensor node measures several physical phenomena, collects and processes data, communicates with other colleagues or central information processing units, sink. This node is able to feel various phenomena, such as pressure, temperature, moisture, position, speed, acceleration, strength, vibration, proximity, movement, biochemical agents, etc. They are able to process textual data, sound and video making it very useful.
According to the National Institute of Standards and Technology (NIST), Cloud Computing (CC) is an innovative technology paradigm that provides convenient network access and on demand to a collection of computing resources that can be configured (for example, sensors) that can be quickly. Provided and released with minimal management efforts or service provider interactions.
Cloud Computing provides several benefits such as self-services, broad network access, resource collection (location independence), fast elasticity, measurable service, large scale, homogeneity, virtualization, strong computing, service software, advanced orientation and security.
The integration of these two main technologies (WSNS and CC) gives us strong infrastructure and can be scaled for several applications such as Smart Grid. This new approach allows the efficient management of millions of meters or smart sensors and other energy management systems. This infrastructure also provides the necessary tools to collect, disseminate and store real-time sensor data from sensors that are geographically different. Cloud components provide the foundation to secure and provide user access to software resources, middleware, and hardware.
