Internet of Things (IoT) is a new and advanced network technology that incorporates inter-object communication and sensor technology that connects almost every controllable electronic device to be used in daily life with a different Internet Protocol (IP) address in a network environment. In a such large-scale network, data transmission, process monitoring, data processing and network traffic are also required to be addressed. Today's Internet architecture uses the TCP / IP protocol stack for communication and is insufficient to meet the needs of the large-scale IoT network. Therefore, it will be a big advantage to reduce the data traffic in an IoT network where large amounts of data will be generated. In this study, a new method for reducing the data traffic in a designed IoT network is proposed and the data traffic on the network is reduced by preventing the transfer of useless / repetitive data in the network environment. A four layered (sensing layer, internet/network layer, transport layer and application layer) IoT architecture has been proposed by Çavdar and Öztürk in 2018. In the sensing layer, it is aimed to prevent unnecessary and repeated data from being transferred in the network environment by analyzing and eliminating the data. In addition, preventing the transmission of unnecessary and repetitive data to the network environment will bring many advantages such as storage, data traffic speed and storage cost.
