| 摘 要： | 由于IEEE802．11MAC协议采用了简单的干扰模型，因此产生了隐藏终端和暴露终端这两个严重影响无线自组织网络性能的问题。文章提出了一种新的基于干扰图（Conflict Graph）的MAC协议——CG-MAC来提高无线自组织网络的吞吐量。通过仿真实验，该协议能够同时解决隐藏终端和暴露终端问题．很大程度地提高了网络性能。

| Abstract: | Due to using the simplified interference model, IEEE 802.11 MAC protocol introduces the hidden and exposed terminal problems which significantly decrease the performance of ad hoc wireless networks. In this paper, we propose a novel Conflict Graph based MAC protocol (CG-MAC) to improve the throughput of ad hoc wireless networks. Through the simulation, our protocol can solve the above two problems caused by 802.11 and improve the network performance substantially. |
