论文摘要
干扰管理已成为调节无线通信网络传输的关键因素。为了支持有效的干扰管理方案,对网络拓扑具有先验知识至关重要。在本文中,我们基于有关消息传递模型模拟的文献中的现有结果,并提出了在试点通信阶段快速发现网络拓扑的有效策略。更确切地说,我们研究了发现一个任意网络拓扑所需的最小通信循环数,每个接收器的链接最大数量,同时假设一个单跳网络仅限于其试验阶段中的基于干扰 - 避免干扰的方案。我们首先忽略了任何干扰取消策略,因此没有接收器能够识别并取消先前发现的发射机的传输,然后在试点阶段捕获通过干扰取消获得的收益。我们的结果表明,所需的回合数量如何以大致对数的方式具有网络中用户总数的实际值,与每个接收器的干扰发射器的数量成正比。
Interference management has become a key factor in regulating transmissions in wireless communication networks. To support effective interference management schemes, it can be essential to have prior knowledge about the network topology. In this paper, we build on existing results in the literature on the simulation of the message passing model, and present an efficient strategy for fast discovery of the network topology during a pilot communication phase. More precisely, we investigate the minimum number of communication rounds that is needed to discover an arbitrary network topology with a maximum number of links per receiver, while assuming a single-hop network that is restricted to interference-avoidance based schemes in its pilot phase. We first ignore any interference cancellation strategy such that no receiver can recognize, and cancel transmissions of, previously discovered transmitters, and then capture the gains obtained through interference cancellation during the pilot phase. Our results evince how the required number of rounds scale in an approximately logarithmic fashion with practical values of the total number of users in the network, having a slope proportional to the number of interfering transmitters per receiver.
