碩士 === 國立臺北大學 === 通訊工程研究所 === 103 === In the information technology industry, device-to-device (D2D) communication within cellular networks can have many useful applications, including in social websites, location-aware services, media networks, and smart grids. This is the reason behind some research into improving D2D communications in everyday, practical application. Some of the challenges currently facing D2D communication, such as interference management, power distribution, resource allocation, channel management, and energy consumption, have yet to be solved. This thesis presents two efficient resource allocation approaches for outband device-to-device communication within cellular networks. The proposed method one has a variety of transmission modes that can be used interchangeably according to network traffic. With this method, much better overall system performance can be achieved. And the proposed method two aims to maximize bandwidth resource utilization and simplify system protocols, greatly optimizing throughput and the number of blocked connections and increasing the ease of operation. Using this method, bandwidth resource can be effectively provided for use according to the level of network traffic. Simulation results verify that our newly proposed method is indeed superior to that of the conventional method.
