Design of a wsn platform for long term environmental monitoring for iot applications
- 1. DESIGN OF A WSN PLATFORM FOR LONG-TERM ENVIRONMENTAL MONITORING FOR IOT APPLICATIONS ABSTRACT The Internet of Things (IoT) provides a virtual view, via the Internet Protocol, to a huge variety of real life objects, ranging from a car, to a teacup, to a building, to trees in a forest. Its appeal is the ubiquitous generalized access to the status and location of any “thing” we may be interested in. Wireless sensor networks (WSN) are well suited for long-term environmental data acquisition for IoT representation. This paper presents the functional design and implementation of a complete WSN platform that can be used for a range of longterm environmental monitoring IoT applications. The application requirements for low cost, high number of sensors, fast deployment, long lifetime, low maintenance, and high quality of service are considered in the specification and design of the platform and of all its components. Low-effort platform reuse is also considered starting from the specifications and at all design levels for a wide array of related monitoring applications. EXISTING SYSTEM More than a decade ago, the Internet of Things (IoT) paradigm was coined in which computers were able to access data about objects and environment without human interaction. It was aimed to complement human-entered data that was seen as a limiting factor to acquisition accuracy, pervasiveness, and cost. But in the existing system there is no immediate updating of information. PROPOSED SYSTEM Two technologies were traditionally considered key enablers for the IoT paradigm: the radio-frequency identification (RFID) and the wireless sensor networks (WSN). While the former is well established for low-cost identification and tracking, WSN’s bring IoT applications richer capabilities for both sensing and actuation. In fact, WSN solutions already cover a very broad range of applications, and research and technology advances continuously expand their application field. This trend also increases their use in IoT applications for versatile low-cost data acquisition and actuation. In our proposed system we chose the WSN as the better solution. Because of the long range communication and as well as the accuracy, there are different sensor which are used to monitor the environment
