优化蜂窝网络中的设备到设备通信

Optimizing Device-to-Device Communications in Cellular Networks

Yuan Hu

摘要:

在本报告中,我们考虑如何动态地选择传输频带和多跳路由,用于与蜂窝网络覆盖共存的设备到设备(D2D)通信。首先,我们考虑不同的无线路由算法,即广播路由(BR)方法,和最短路径路由(SPR)方法。结果表明,根据共存蜂窝用户的中断约束,不同的路由策略具有不同的优点。BR在低D2D用户密度下是可接受的,但在高密度下是可怕的。我们还考虑了信道频带性能(上行链路频带和下行链路频带)。结果表明,多跳D2D使用上行链路频带可以实现低中断概率(约5%),并且在下行链路频带中的D2D在SPR下表现得稍差(约12%)。

英文摘要:

In this report, we consider how to dynamically select transmission bands and multi-hop routes for device-to-device (D2D) communications in co-existence with a cellular network overlay. Firstly, we consider different wireless routing algorithms, i.e. broadcasting-routing (BR) method, and shortest-path-routing (SPR) method. The results show that depending on the co-existence cellular users' outage constraint, different routing strategies have different merits. BR is acceptable at the low D2D user density but is terrible at high density. We also consider the channel band performance (Uplink band and Downlink band). The results show that the multi-hop D2D can achieve a low outage probability using the uplink band (approximately 5%), and D2D in the downlink band performs a little poorly (approximately 12%) outage with SPR.
