Abstract

Collision-Aware-Intel (CA-Intel) which is a modified version of the widely used Rate Adaptation Algorithm (RAA), Iwl-Mvm-Rs, is proposed to enhance performance by incorporating collision awareness. CA-Intel builds upon Iwl-Mvm-Rs by introducing an error condition estimation mechanism and an adaptive Request-To-Send/Clear-To-Send (RTS/CTS) mechanism. The presence of collisions is detected by analyzing the difference in Frame Error Rates (FERs) between transmissions protected by RTS/CTS and those that are not. Then it will adaptively enable the RTS/CTS mechanism based on current error conditions to avoid collisions. CA-Intel has been implemented in the ns-3 simulator, demonstrating that it effectively reduces FER and improves throughput.

面向 IEEE 802.11 WLAN 的碰撞感知英特尔速率自适应算法

碰撞感知英特尔（CA-Intel）是广泛使用的速率适应算法（RAA）--Iwl-Mvm-Rs--的一个改进版本，通过结合碰撞感知来提高性能。CA-Intel 以 Iwl-Mvm-Rs 为基础，引入了错误条件估计机制和自适应请求发送/清除发送（RTS/CTS）机制。通过分析受 RTS/CTS 保护的传输与未受 RTS/CTS 保护的传输之间的帧错误率 (FER) 差异，检测是否存在碰撞。然后，它将根据当前的错误条件自适应地启用 RTS/CTS 机制，以避免碰撞。CA-Intel 已在 ns-3 模拟器中实现，证明它能有效降低 FER 并提高吞吐量。

期刊介绍： The IEEE Communications Letters publishes short papers in a rapid publication cycle on advances in the state-of-the-art of communication over different media and channels including wire, underground, waveguide, optical fiber, and storage channels. Both theoretical contributions (including new techniques, concepts, and analyses) and practical contributions (including system experiments and prototypes, and new applications) are encouraged. This journal focuses on the physical layer and the link layer of communication systems.
