流星突发通信数据采集网的研究

A Study of Meteor Burst Communication Network for Data Acquisition

本文以边远地区自动水文、气象数据采集网为对象进行流星突发通信系统组网研究,利用流星余迹的空间特性完成了网络内部结构的设计;为提高通信的有效性提出了子群查询,全应答和逐址查询相结合的网络多址协议;将点对点通信系统中用以评价系统性能的平均等待时间等概念在网通信中作了推广。分析与计算的结果表明,本文所设计的系统要优于美国同类SNOTEL系统。

This paper presents a meteor burst communication network developed for auto hydrological and meteorological data acquisition from outlying districts. The internal structure of the net is designed according to the spatial properties of meteor trails. A new protocol together with Subgroup Polling, AU Remotes Answering and Polling Remote by Remote are proposed to increase communication efficiency. Also, the paper extends the concepts, such as the Average Waiting Time which is used to evaluate the system performances, from point-to-point mode to network mode. The results of computations and analysis show that the performance of the system designed here is better than that of the SNOTEL system .
