IOT based energy efficient security system

摘要

Internet of things can support Enormous applications and services in various sectors such as smart cities and smart homes. IOT smart objects and it's components interact with other components Ex: proxies, mobile devices and data collectors along with various sensors for management, data sharing and other activities in the context of provided services. In recent years Raspberry Pi is being used enormously for the implementation of IOT applications. Here in particular we use Raspberry Pi to capture and compress images. Raspberry Pi board is mounted with PIR sensor which detects the movements around it, and a Pi camera which captures the image when movement is encountered the captured image is compressed on the raspberry pi using SVD compression methodology after which the compressed image is transmitted over the network to the desktop application where it is decompressed on the receiving end using Matlab. The primary aim of this paper is to achieve image compression which reduces considerable image size in terms of bytes during transmission to reduce latency issues and communication bandwidth during transmission of the image over the network and simultaneously preserve the useful features of the image.
