Survey on Providing Security and Authentication for Devices to Achieve QOS in IOT

The IOT (Internet of Things) is a network which connects things to the Internet for the intend of interchanging information through the information sensing devices with acceptable protocols. Sensing Devices utilize in households and smart city is now interconnected with the Internet. This interconnection provides a whole range of data (industrial context, device status, etc. ) that can be collected, aggregated, and then shared in secure, and privacy-aware manner. Some essential fields such as Wireless Sensor Network and Intelligent Transport System (ITS), base nodes collect information and transmit it to the destination nodes. Destination sends commands by the relay devices to the base nodes. Thus how maintain the security of both base nodes and destination nodes in this kind of communication is a pressing problem
