IOT Based Environment Monitoring using Wireless Sensor Network.

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. The Internet of Things (IoT) is the network of physical objects, devices, vehicles, buildings and other items which are embedded with electronics, software, sensors, and network connectivity, which enables these objects to collect and exchange data. WSNs are integrated into the ―Internet of Things‖,where sensor nodes join the Internet dynamically, and use it to collaborate and accomplish their tasks. 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 long-term environmental monitoring IoT applications. Copy Right, IJAR, 2017,.

Introduction:-The future Internet, designed as an ―Internet of Things‖ is foreseen to be ―a world-wide network of interconnected objects uniquely addressable, based on standard communication protocols‖ [1]. Identified by a unique address, any object including computers, sensors, RFID tags or mobile phones will be able to dynamically join the network, collaborate and cooperate efficiently to achieve different tasks. . Including WSNs in such a scenario will open new perspectives. Covering a wide application field, WSNs can play an important role by collecting surrounding context and environment information.Key enablers for the IoT paradigm are : RFID and WSN. RFID is well known and established for low-cost identification and tracking. WSNs 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.However, the sheer diversity of WSN applications makes increasingly difficult to define ―typical‖ requirements for their use in IoT applications [2]. The generic WSN platforms can be used with good results in a broad class of IoT environmental monitoring applications. However, many IoT applications (e.g., those in open nature) may have stringent requirements, such as very low cost, large number of nodes, long unattended service time, ease of deployment, low maintenance, which make these generic WSN platforms less suited. Related Work:-WSN environmental monitoring includes both indoor and outdoor applications. The later can fall in the city deployment category (e.g., for traffic, lighting, or pollution monitoring) or the open nature category (e.g., chemical hazard, earth-quake and flooding detection, volcano and habitat monitoring, weather forecasting, precision agriculture). The reliability of any outdoor deployment can be challenged by extreme climatic conditions, but for the
