In this day and age, Internet use is growing, so another area has developed to use the Internet, called the Internet of Things (IoT), It facilitates the communication, computation and coordination of machines and objects. Internet of Things (IoT) or Web of Things (WoT) is emerging technology and it wireless network between two or more smart objects or smart things connect via Internet. IoT classified in two type first is inside of IoT and second side is outside of IoT. In inside of IoT consider as protocols in IoT. In outside of IoT consider as sensor, actuators, etc, those are physically possible. In inside of IoT consider as Protocols and IoT have their own protocol stack. Protocol stack have different layer like Application layer, Transport layer, Internet layer and Physical/Link layer. IoT's role is to ensure open and effective communication between two objects and use different applications to build a continuous bond between them. IoT has many obstacles and security and privacy are some of the core issues associated with IoT's broad application.
