Hanwate Department of Computer Engineering, NBN Sinhgad School of Engineering, Pune Savitribai Phule Pune University, Pune-411041, India Abstract: - Internet of Things is an emerging technology and is being developing nowadays. Therefore the communication between the devices is an important factor in IoT. Devices will communicate with each other intelligently, without any centralized control and gather, share and forward the information in a multihop manner, ultimately, the quality of gathered information depends on the achieving device to device communication. In device to device communication, the devices can communicate with each other by using the Bluetooth controller which can be used for establishment of the communication between the devices. The devices interact with physical world using internet protocols and standards in order to collect data from the environment. Thus we are going to present an overview of how intelligent device to deice communication can be achieved in the IoT system. Keywords - IoT, Intelligent Device, Device to Device Communication, Bluetooth, WIFI, Sensor. I. INTRODUCTION ith the approach of the internet, people are connected in a large number. However, due to the proliferation of short range networks and the prevalence of devices connected to these networks, a seamless interconnection between devices is gradually being created. These short range networks consist of wireless sensor network (WSN), Bluetooth, ZigBee. By using such technologies the communication can be done in the network. It helps in the data gathering, sharing, etc. For information sharing, gathering will involve certain series of communication between the devices. The communication between the devices is done by the using the concept of IoT. IoT is the technology where everything is connected to the Internet. The devices interact with the physical world using Internet protocols and standards in order to collect data from the environment. For the complete IoT concept, cloud computing offers a dynamic way of accumulating and storing data. Using IoT the communication between the devices is automated, which reduces the human effort and time. These automated devices can transfer the required information among the devices and thus the work can be done with perfection and without human interference. II.

The communication between devices with or without human intervention can be done by the process of sharing, gathering, and creating information. As people have become largely interconnected to the internet however due to short-range network and the devices connected to these network,interconnection between devices is gradually being created. The short-range networks include wireless sensor networks(WSNs),wirelessfidelity(Wifi)Bluetooth, radio- frequencyidentification(RFID) networks, and ZigBee. Thus current Market examples include smart thermostat systems and washer/dryers that use Wi-Fi for remote monitoring. In 1982, with modified Coke machine at Carnegie Mellon University becoming the first internet-connected appliance. The concept in IEEE Spectrum as "[moving] small packets of data to a large set of nodes, so as to integrate and automate everything from home appliances to entire factories" was described by Reza Raji in 1994. In 1999, Bill Joy visualized Device to Device communication. Therefore in 1999 the concept of IoT becomes popular through the Auto-ID center at MIT and related market-analysis publication. Present system include Manual Intervention required system and Manually ON/OFF or controlling system. IV.PROPOSED SYSTEM ARCHITECTURE W
