Smart environment

Abstract

Smart environment is a technological concept in which the physical world that is richly and invisibly interwoven with sensors to gather and process their sensed data. While using certain communication framework send this information to actuators which take certain actions to control the environment. The SMART ENVIORNMENT project is exactly based on the same idea. The two basic things of interests in our smart environment are intrusion and overheating detection for fire. The reason for the selection of these two entities is that security and safety are critical in all aspects of today’s world. In order to ensure safety easily deployable and easy to afford solutions are required. The Smart Environment Project is just one of those solutions that can be used as a basic tool for the detection of intrusion with homes and offices along with the provision to detect overheating. For this purpose, Texas Instrument’s Ez430-RF2500 devices are used which are equipped with temperature sensors while PIR sensors for intrusion detection are also attached to these devices for intrusion detection. Ez430-RF2500 are low power and resource constrained which support a star topology network. The basic aim of this project is to establish a multi-hop network with these devices to enhance the coverage area of the network for which IETF ROLL (Routing on Low power and Lossy networks) routing protocol has been implemented on these devices. A desktop application (Smart Monitoring System) is also developed to graphically represent the gathered information from different field sensors. This application generates visual, audio and sms based alerts to notify the end user in case of any critical event.
