轮询卫星通信网应用初探

Brief Discussion on the Application of Satellite Communication Network Based on Polling Strategy

传统卫星通信组网方式有预分配和按需分配等方式，而在基于卫星通信的海洋信息采集网中，数据传输具有明显的不对称性和单向性，传统的通信组织方式不利于有效利用卫星资源。本文引入了轮询系统的基本思想，提出了适用于数据采集网的卫星传输轮询策略，阐述了动态优先权队列的实现原理，并分析和比较了传统体制卫星网和轮询体制卫星网的异同和优缺点。

There are two networking modes for traditional satellite communication networking： pre-distribution and distribution on demand. In the ocean information collection system based on satellite communication, data transferring is non-symmetrical and unidirectional. The traditional communication is not fit for utilizing satellite resource effectively. So in the paper, we introduce the basic theory of polling system, put forward a satellite transmission polling strategy suitable for data collection system, explain the basic theory of dynamic priority queue, and compare the difference, advantages and disadvantages between traditional satellite communication network and polling satellite communication network.
