| 摘 要： | 分别采用静态链状拓扑和动态网络拓扑,通过仿真分析和比较了不同TCP版本在移动AdHoc网络中的性能。文中还提出了一种改进的选择性应答算法(SSACK),以解决移动AdHoc网络中由于高丢包率和路由重建引起的TCP接收窗的"缺口(gap)"问题。仿真结果显示,改进的SSACK算法在一定程度上改善了移动AdHoc网络中的TCP性能。

| Abstract: | TCP throughput performance of different TCP variants are compared and analyzed in detail by simulations both under static chain topology and under dynamic network topology of mobile Ad Hoc networks. An improved selective acknowledge algorithm (SSACK) is proposed to solve the "gap" problem in TCP receiver''s window caused by high packet loss rate and link re-establishment of mobile Ad Hoc networks. Simulations show that the improved algorithm can improve TCP performance in mobile Ad Hoc networks considerably and leave more reservation space of TCP option for future use. |
