Nowadays, the development of science and technology is actively contributing to the implementation of Industry 4.0 tools. One of these tools is the Internet of Things (IoT), which allows to connect a large number of physical objects and devices into one digital network. The IoT networks are the key to increasing the efficiency of industrial enterprises, transport infrastructure, monitoring and information collection systems, smart houses, smart cities, and others. The rapid development of wireless information transmission systems has led to a rapid increase in the use of such technologies in IoT networks. However, the large number of sensors in IoT networks has caused new challenges for the use of wireless architecture. Such challenges include ensuring electromagnetic compatibility, frequency resource allocation, communication channel stability, and effective data routing. Therefore, the purpose of this paper is to develop a novel routing approach in dense wireless IoT network scenarios that will increase the speed of data transmission based on determining the optimal route between the nodes in case of presence of interference from neighboring nodes on the route. The proposed approach has 35% gain in transmission rate while employing the IEEE 802.11n standard.
