Abstract: In this paper, a heterogeneous network consists of Device to Device (D2D) communication users and Cognitive Radio (CR) network users are considered. D2D users can communicate through licensed band or unlicensed band. Unlicensed band accessing D2D users are called as D2D-U users. CR users are using the unlicensed band for data transmission and they have the capability to access the licensed band when it is not in use. This proposed system is considering D2D-U users and Wi-Fi users in a local geographical area and applying scheduling technique for both to access the licensed band without affecting the licensed user’s transmission. The proposed system evaluated the data sum rate against number of user. The simulation results are generated and discussed.
