Legacy infrared (IR) devices are pervasively used. They are often controlled by IR remotes and cannot be controlled over the Internet. A trustworthy and cost-effective smart IR system that is able to change an IR controllable device into a smart IoT device and interconnect them for smart city/home applications is offered in this paper .Today, Infrared remote control technology has been applied to various aspects of our life and production. It is used not only in the high-end technology, such as aerospace, but also in all kinds of remote controls in our daily life. We use Legacy IR devices in our day to day life for that we are still using remote controls. Hence for that there are various ways we can connect IR devices. Also we have described a webized augmented reality mashup for legacy things that connects existing web services with things without the additional cost of replacing existing devices. Also describes a way that legacy Device Bridge performs protocol conversion to enable a network- work-attached entity. As well device for providing a service record for an application (e.g., a legacy application) running on a virtual serial port of a wireless transceiver device, such as a Bluetooth-enabled device is mentioned. The methods which are described in this paper uses Bluetooth, cloud server which uses MQTT protocol, ZigBee protocol, Webized augmented reality mashup, Fog/edge computing. As well as security concerns regarding the method which will help to control IR legacy devices is discussed in this paper. Technologies which are used for controlling IR devices are discussed Key Words: IR legacy devices, ZigBee protocol, Fog/edge computing, Webized augmented reality mashup, Bluetooth. 1. INTRODUCTION Home automation market is very auspicious sector which is developing rapidly. It requires extensive range of developments that can be made in the idea of smart homes. IoT has broad applications including smart home, smart city, smart grid and smart transportation. However, there still exist a large number of legacy devices such as infrared (IR) controllable devices, which cannot be controlled over the Internet[7]. Home automation is also known as domotics. This involves the control and automation of lighting, heating, ventilation, air conditioning, security. It also includes control and automation of home appliances such as washers/dryers, ovens or refrigerators/ freezers. Home automation is a modern technology that transforms your home to an extent that it can perform different sets of task automatically. This technology is constantly upgrading its versatility by integrating modernized features to fulfill the increasing demands of people .Main purpose of home automation system is to save electricity. Smart home automation is beneficial for us as it added more comfort. [10].The infrared technology is used in many different fields including scientific research, business, and military. The infrared spectrum can be divided into five categories: near infrared, short wavelength infrared, mid wavelength infrared, long wavelength infrared, and far infrared [11] This paper contains various methods to connect IR legacy devices to our phones which will make our work to control IR devices easy. This paper demonstrate various ways to control IR legacy devices like TV, AC 2. LITERATURE SURVEY In 2004 David Kammer [1] patent a method and device for providing a Service record for an application(e.g., a legacy application) running on a virtual Serial port of a wire-less transceiver device, such as Bluetooth enabled devices. It can lose connection in certain conditions. It has low bandwidth as compared to Wi-Fi. It allows only short range communication between devices. In 2011 Paul Krzyzanowski, et al [3], carried out study of the legacy device bridge which translates between packet-based communication protocols, such as TCP/IP, and communication protocols used by legacy electronic consumer IR devices, such as IR and serial protocols, in order to perform this function. It is slower compare to repeaters because of filtering. It does not filter broadcasts. It is more ex-pensive compare to repeaters. We can configure controllable CE de-vices based on user’s mobility and minimize power consumption based on ZigBee ON/OFF control technique using multiple level timers. The zigbee has flexible network structure. It is low power consumption. For official private information it is highly risky. The zigbee has low transmission rate .It is not secure like wifi based secured system. A dynamic control scheme for multiple legacy IR controllable digital CE devices based on ZigBee protocol was proposed in 2007 by Wan-Ki Park, et al [2]. In 20017 Daeil Seo, et al [4], have published their paper in which they described webized augmented reality mashup for legacy things that connects existing web services with things
