||Distributed Resource Allocation Based On Clustering In Device to Device Communication|
|Date of Defense
||With the increasing number of mobile devices and the dramatic increase in network traffic, the mobile communication networks are facing spectrum efficiency or spectrum utilization problem. At same time increasing the spectrum is very difficult. Therefore, to enhance the system data flow and reduce the load, between Device to Device (D2D) communications technology in recent years has more attention.|
D2D does not transfer through base station and can communication directly. But adding D2D in cellular networks becomes more complex. D2D can reuse cellular UE‘s spectrum and enhance spectrum efficiency, but cellular UEs also suffer serious interference from D2D. It is necessary to consider the quality of each UEs in order to avoid interference caused by D2D, and how to coordinate information and signal strength of each device used for D2D communication is very important.
Based on previous studies, it has not been considered whether there is a serious effect to meet demand for resources for each UE, and whether all UE allocation of resources and management by eNB will result in time delay. By taking advantage of distributed architecture using cluster approach we improved the effectiveness of the cellular network, by dispersing in cluster management and resource allocation through Cluster Head. Because Cluster Head consumes large amounts of energy, in this paper we consider energy issues and increase the number of Cluster Heads with the growing number of UEs.
In this paper we propose the interference suppression mechanism and expand services coverage by introducing Cluster Heads. Regardless of serious interference or at cell edge of the UE our goal is to meet demand for services. To combine the advantages of D2D and eNB reduce time delay and enhance D2D user satisfaction ratio.
