无线网络中通过功率控制进行干扰管理既有引起传输冲突的隐藏终端问题，也有阻塞并发传输的暴露终端问题。这两个问题都是由不同链路的干扰范围不同引起的。通过观察采用功率控制机制的节点在一种情况下会引发冲突，而在两种情况下会错过并发的传输机会，提出了一种新的基于干扰感知的功率控制协议IAPC（Interference-Aware Power Control），从三个方面提高网络吞吐量。IAPC利用特征检测过程，使其CTS（Clear-To-Send，清除发送）传输覆盖各链路的干扰范围，从而避免干扰。同时，它使CTS帧携带该链路的发送和接收功率信息，相邻节点可以根据该信息确定有限的发送功率，试图使自己处于正在进行的链路的干扰范围之外，以便利用并发传输。通过实验结果和理论分析，研究了IAPC协议的特征检测范围，并通过ns 2仿真实验验证了IAPC协议与其他协议相比的性能改善。
Interference management through power control in wireless networks has both the hidden terminal problem which induces transmission collisions, and the exposed terminal problem which blocks concurrent transmissions. Both problems are caused by the varied interference range of different links. Through observing that the nodes adopt the power control mechanism induce collisions in one scenario and miss concurrent transmission opportunities in two scenarios, this paper presents IAPC (Interference-Aware Power Control), a novel protocol to improve the network throughput from the three aspects. IAPC makes the interference range of each link covered by its CTS (Clear-To-Send) transmission through utilizing a signature detection process, so as to avoid interference. Meanwhile, it makes the CTS frame carry the transmission and reception power information of this link, according to which the neighboring node can determine a limited transmission power, trying to make itself outside the interference range of the ongoing link, so as to exploit concurrent transmissions. The signature detection range has been investigated through both experiment results and theoretical analysis, and the performance improvement of IAPC comparing with the other protocols has been shown through simulation results based on ns2.
