本文分析了ALOHA、时隙ALOHA和时隙CSMA在应答业务与信息业务共用同一信道条件下的吞吐量和时延性能。所考虑的应答业务是由传输协议产生的,从而需重点考虑信息分组与其应答分组在到达时间上的相关性。分析结果表明,不同的应答协议对吞吐量和时延影响有明显的差别。
This paper analyzes the throughput and latency performance of ALOHA, slotted ALOHA and slotted CSMA in response to the same channel condition when the service and information service share the same channel. The considered answering service is generated by the transmission protocol, so that the correlation between the information packet and its response packet needs to be emphatically considered. The analysis results show that different response protocols have significant differences on throughput and latency.
