摘要

针对蜂窝场景下的高吞吐量无线通信，提出了一种具有碰撞分辨率的ALOHA (ALOHA- cr)跨层方案。传输以一种时隙aloha类型的方式发生，但有一个重要的区别:两个用户同时传输可以成功。本文对吞吐量和业务延迟进行了分析，并在包含软件定义无线电(SDR)试验台的无线开放存取研究平台(WARP)[14]试验台上对分析结果进行了验证。分析和实验表明，ALOHA-CR可以显著提高吞吐量，减少服务延迟。

ALOHA with Collision Resolution: MAC layer analysis and software defined radio implementation

A cross-layer scheme, namely ALOHA with Collision Resolution (ALOHA-CR), is proposed for high throughput wireless communications in a cellular scenario. Transmissions occur in a time-slotted ALOHA-type fashion but with an important difference: simultaneous transmissions of two users can be successful. In this paper, throughput and service delay analysis is provided and the analytical results are validated on the Wireless Open Access Research Platform (WARP) [14] testbed containing software defined radio (SDR) testbed. Both analysis and experiments indicate that ALOHA-CR leads to significant increase in throughput and reduction of service delays.
