碩士 === 國立臺灣師範大學 === 電機工程學系 === 106 === Device-to-Device(D2D) communication is an important technique in Long Term Evolution (LTE) system, which can communicate with each other without connecting to the base station. Therefore, the loading of the base station could be reduced and the network capacity of the whole system could be increased. In this thesis, we purpose a step by step location recommendation algorithm for D2D communication underlying LTE cellular networks. With this algorithm, a recommendation path could be designed where D2D pairs move to. System capacity and efficiency of the whole network could be improved by this way. The experiments simulate an environment containing main base stations and several pairs of D2D to verify the step-by-step location recommendation algorithm proposed in this paper for D2D communications, and the LTE-Sim open source tool is utilized here to measure the simulation results. Experimental results show that the transmission performances of overall system can achieve significant improvement in various circumstances.
