摘要: |
自组织时分多址(SOTDMA)协议是实现AIS系统的核心技术,该技术以自组织的方式
工作,在交通繁忙区域,系统很有可能出现时隙冲突。针对这一情况,在OPNET环境下,对
系统的报告率、时隙冲突率及系统容量等三方面进行了仿真,仿真结果对AIS系统的工程化
具有非常重要的参考作用。 |

Abstract: |
Selforganized time division multiple access (SOTDMA) protocol is the
key technology of Automatic Identification System(AIS),and it works in selfor
ganized mode, in busy area, th
e selected slot would be collided. Based on OPNET, this paper mainly studies th
e r
elationship of the report rate, the probability of slot collision and the networ
k capacity. The result is helpful for the engineering of AIS. |
