在大型无线网络中，获取完整的网络状态信息通常是不可行的。因此，节点需要基于关于网络的部分信息来流动信息并管理干扰。在本文中，我们考虑多跳无线网络，并假设每个源只知道从自己到网络中的其他目的地的路由上的信道增益。我们开发了几种分布式策略来管理用户之间的干扰，并证明了它们在最大化某些类网络的可实现归一化和速率方面的最优性。
In large wireless networks, acquiring full network state information is typically infeasible. Hence, nodes need to flow the information and manage the interference based on partial information about the network. In this paper, we consider multi-hop wireless networks and assume that each source only knows the channel gains that are on the routes from itself to other destinations in the network. We develop several distributed strategies to manage the interference among the users and prove their optimality in maximizing the achievable normalized sum-rate for some classes of networks.
