短波地空网中一种动态TDMA协议设计与仿真
针对传统TDMA网络节点间业务量不均匀时,会造成信道资源严重浪费的问题,设计了一种基于邻居时隙调动的短波地空网动态TDMA协议（NTR-TDMA）,以可靠性较高的地面节点作为控制中心,实现时隙分配可控下的动态利用。提出了邻居时隙调动算法（NTR-ALG）,地面节点根据时隙估计过程后生成的节点时隙请求数,调动相邻业务时隙节点间的空闲时隙,重新划分节点业务时隙界限。利用OPNET平台进行性能仿真,并与HFTP协议和TDMA协议作了对比分析。仿真结果表明,NTR-TDMA相比HFTP协议和TDMA协议,在消息投递率、平均时延和吞吐量方面具有更优异的性能。...
