Joint Mode Selection and Resource Allocation Using Evolutionary Algorithm for Device-to-Device Communication Underlaying Cellular Networks

چکیده
Device-to-Device (D2D) has been a potential technology to improve the sum-rate of cellular networks, especially in local communication. By reusing the resource of cellular user equipment (UE), D2D can enhance the spectrum efficiency, but at the cost of introducing extra co-channel interference. In this paper, we adopt a resource reusing mechanism in which multiple D2D pairs can share multiple resource block for the sake of higher sum-rate, and then propose a joint mode selection and resource allocation method based on evolutionary algorithm (EA-MSRA-MDMR) to reduce the extra interference. Simulations show that the proposed method can achieve a higher system sum rate and fairness.
