TCP Veno在MANET环境下的性能研究
Performance study of TCP Veno in MANET environment
【摘要】 将TCP Veno运行在MANET环境下,采用NS2对其性能进行了仿真测试。仿真结果表明:在存在背景流、有随机丢包并且存在拥塞的MANET网络中,TCP Veno的性能优于TCP Reno,而且在背景流越大,达到拥塞的时间越短、随机丢包越大,TCP Veno的优越性更会非常明显。
【Abstract】 The performance of TCP Veno is tested by using NS-2 in the MANET environment.The simulation results show that the performance of TCP Veno is superior to that of TCP Reno in the MANET environment with background traffic,random packet loss and congestion;furthermore,the larger background traffic and random packet loss are,and the shorter time congestion takes,the more obvious the superiority of TCP Veno is.
