低轨卫星接入系统中基于位置信息的时隙分配协议
A Position-based Slot Assignment Protocol for LEO Satellites Network
摘要
Abstract
To solve the long end-to-end delay and low throughput problem in unified delayed allocation protocol with wide coverage and long propagation delay of access link in buoy satellite communication sys-tem,this paper proposes a position-based slot assignment protocol. Satellites use position information of bu-oy to control the start position of slot allocation in the protocol,achieving discrete slots allocation to increase the available transmission slot length and reduce transmission delay. The OPNET simulation results show that the proposed slot allocation protocol can significantly improve network throughput under single-channel transmission mode,and effectively reduce buoy satellite communication system′s access delay under either the single-channel mode or the dual-channel mode.关键词
