Abstract

Contention Resolution Diversity Slotted ALOHA (CRDSA) random access scheme, introduced in the DVB-RCS2/NG standard, is specifically designed to support the transfer of a variety of traffic profiles that Machine to Machine (M2M) and Internet of Things (IoT) applications may generate. Protocols for M2M and IoT has recently receiver substantial upgrades, but still mainly designed with an underlying terrestrial network in mind. If clusters of sensor nodes exchange data via satellite terminals toward a sink via short-lived TCP/IP connections, many shortcomings may incur. This work aims at investigating in details the behavior for such data transfer in presence of a shared random access channel, and the advantages when using a new TCP version specifically designed for satellite links, namely TCP Wave. In particular, through a detailed simulation campaign based on the NS3 simulator, this work assesses the completion time of data delivery for M2M elastic traffic via CRDSA satellite random access, when standard TCP (NewReno) or dedicated satellite TCP (Wave) is adopted.

随机访问链路上卫星M2M应用的TCP性能

DVB-RCS2/NG标准中引入的争用分辨率分集开槽ALOHA (CRDSA)随机接入方案，专门用于支持机器对机器(M2M)和物联网(IoT)应用可能产生的各种流量配置文件的传输。M2M和物联网的协议最近得到了实质性的升级，但主要设计时仍然考虑到底层地面网络。如果传感器节点集群通过卫星终端通过短暂的TCP/IP连接向接收器交换数据，可能会产生许多缺点。这项工作的目的是详细调查在共享随机访问通道存在时这种数据传输的行为，以及使用专门为卫星链路设计的新TCP版本(即TCP Wave)时的优势。特别是，通过基于NS3模拟器的详细仿真活动，本工作评估了采用标准TCP (NewReno)或专用卫星TCP (Wave)时，通过CRDSA卫星随机接入的M2M弹性流量的数据传输完成时间。
