    Abstract: The Internet of Things (IoT) is the major elements of smart cities when we can see IoT devices in any
points of our environment. There is need to special security policy to safe communication in IoT structure. In
this study, we propose an approach to provide security in IoT communication. Proposed algorithm uses polling
system to enable user’s opinion about secure routing. The fuzzy system is used in this study to combine the
votes.
