摘要:

在超密集 D2D 通信中,目前的中继选择方案主要假定中继设备具有主动意愿参与数据转发,但部分理性中继设备出于自身考虑,可能会存在时延或拒绝转发的自私行为,进而影响用户体验效果。从中继设备自私行为角度出发,提出了D2D通信中自私中继设备识别方法,进而提出了基于自私行为分析的超密集D2D中继选择算法。首先,定义了联合兴趣度、转发历史比率和中继物理状态3个中继识别属性因子,并通过三角模糊函数计算三者的权重,从而对具有自私行为的中继设备完成识别。其次,基于理想解相似性偏好排序方法实现了中继设备的最终选择方案。仿真结果表明,所提算法能更有效地识别 D2D 通信中的自私中继设备,与其他中继选择算法相比,在D2D通信转发成功率、系统平均吞吐量和平均时延等方面均取得了显著进步。

Abstract:

In ultra-dense D2D communication, the current relay selection schemes mainly assume that the relay device has the initiative to participate in data forwarding, but some rational relay devices may delay or refuse to forward due to their own considerations, thus affecting the user experience.From the perspective of selfish behavior of relay devices, a method to identify selfish relay devices in D2D communication was proposed, and then an ultra-dense D2D relay selection algorithm based on selfish behavior analysis was proposed.Firstly, three relay identification attribute factors, namely joint interest degree (JID), forwarding history ratio (FHR) and relay physical state (RPS) were defined, and their weights were calculated by triangular fuzzy function to identify relay devices with selfish behavior.Secondly, based on the TOPSIS (technique for order of preference by similarity to ideal solution) method, the final relay equipment selection scheme relay was realized.Simulation results show that the proposed algorithm can identify selfish relay devices more effectively in D2D communication.Compared with other relay selection algorithms, the proposed algorithm has made significant progress in the aspects of D2D communication forwarding success rate, system average throughput and average time delay.

Key words: mobile communication, device to device, relay selection, selfish behavior
