Embodiment Construction
[0054] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0055] In the environment of a single cell, there are N users. These N users can directly communicate with the BS (base station, base station) through a cellular link, or form a D2D cluster according to their own conditions. Users in the D2D cluster can communicate with each other. D2D communication meets its own needs and reduces communication co...

The invention provides a trust degree and physical distance based D2D (Device to Device) communication node clustering method and device. The trust degree and physical distance based D2D communication node clustering method comprises obtaining the physical distance between a first user and a second user; obtaining the trust degree between the first user and the second user; calculating a selective probability value between the first user and the second user according to the physical distance between the first user and the second user and the trust degree between the first user and the second user so as to obtain a selective probability value between every two users in a community; performing D2D communication node clustering on the users in the community according to the selective probability value between every two users in the community. According to the trust degree and physical distance based D2D communication node clustering method and device, the trust degree and physical distance based clustering method in the D2D communication field is given and accordingly the improvement of the system throughput and efficiency is effectively implemented.
Description
technical field [0001] The present invention relates to the field of communication technology, in particular to a method and device for clustering D2D communication nodes based on trust degree and physical distance. Background technique [0002] D2D (Device to Device) communication is widely used in hotspot area services, and D2D clusters are usually formed and communicated between adjacent users. Due to different spectrum sharing methods, D2D communication has different working modes. The overlay spectrum sharing method reserves dedicated spectrum resources for D2D communication, while in the underlay method, D2D users reuse the spectrum resources of cellular users without interfering with cellular user communications. Since most of the devices for D2D communication are handheld devices, the trust between the holders of these devices also plays a key role in D2D communication. Therefore, in the D2D communication between user equipments, it is necessary to consider the ind...
