论文摘要
在本文中，众所周知的交升者的困境通过考虑链接质量波动的存在来概括。转发器的困境是一个具有两个源节点和两个目标节点的四节点交互模型。众所周知，研究临时网络非常有用。为了表征源节点必须通过部分通道状态信息（CSI）控制其功率时的长期效用区域，我们求助于香农理论的最新结果。它显示了如何利用这一理论结果来找到长期实用区域并确定良好的功率控制策略。该区域至关重要，因为它为节点上给定的知识提供了最佳性能。数值结果为重复转发器的困境能力控制问题提供了一些新的见解。例如，全球CSI的知识仅带来有关本地CSI案例的边缘性能提高。
In this paper, the well-known forwarder's dilemma is generalized by accounting for the presence of link quality fluctuations; the forwarder's dilemma is a four-node interaction model with two source nodes and two destination nodes. It is known to be very useful to study ad hoc networks. To characterize the long-term utility region when the source nodes have to control their power with partial channel state information (CSI), we resort to a recent result in Shannon theory. It is shown how to exploit this theoretical result to find the long-term utility region and determine good power control policies. This region is of prime importance since it provides the best performance possible for a given knowledge at the nodes. Numerical results provide several new insights into the repeated forwarder's dilemma power control problem; for instance, the knowledge of global CSI only brings a marginal performance improvement with respect to the local CSI case.
