摘要：
In this paper, we propose a cooperative relay selection scheme based on geographical information in cellular networks. According to the current user equipment density in a certain cell, we firstly choose the potential relays among the user equipments. Then, the localization algorithm based on time difference of arrival has been adapted to locate- the potential nodes. Finally, we. select the cooperative relay from the potential relays based. on the known geographical information. We also give simulation experiments. Simulation results show that. the scheme can choose the best cooperative relay to increase effectively the user capacity and to improve system performance as well.
