The recent upsurge of mobile devices such as smartphones and tablets has caused scarcity of network resources, such as spectrum and computation resources. Moreover, mobile devices ordinarily join or leave networks for their own convenience, resulting in high network dynamics. As a result, developing advanced technologies based on the concepts of cooperation, sharing, and reusing becomes necessary for wireless networks. As one of the promising solutions, online truthful mechanism design has been introduced in wireless networks in order to motivate the participation of more mobile users under a dynamic environment. This article first introduces the origination and some basic concepts of the online truthful mechanism, and then provides an exhibition of several online truthful mechanism design methods, which have been widely applied in wireless networks. We primarily present two types of online truthful mechanisms, that is, primal-dual based and time slotted online mechanisms, and then briefly summarize other classes, including Myerson-based, random-based, and matching-based ones.

无线通信网络中的在线真实机制设计

最近智能手机和平板电脑等移动设备的热潮导致了频谱和计算资源等网络资源的稀缺。此外，移动设备通常为了自己的方便而加入或离开网络，导致高网络动态。因此，开发基于协作、共享和重用概念的先进技术成为无线网络的必要条件。作为有前景的解决方案之一，无线网络中引入了在线真实机制设计，以在动态环境下激励更多移动用户的参与。本文首先介绍了在线真实机制的起源和一些基本概念，然后展示了几种在线真实机制的设计方法，在无线网络中得到了广泛的应用。我们主要介绍两种在线真实机制，即基于原始对偶和时隙在线机制，然后简要总结其他类，包括基于 Myerson、基于随机和基于匹配的类。
