| 摘 要： | 在MANET中,节点的移动性会导致在接收端产生大量的乱序数据包,影响TCP协议的性能.提出了一种改进的TCP协议(TCP-D),通过延时触发拥塞控制算法,来提高TCP协议在MANET中的性能.对延时响应TCP协议的吞吐量分析表明,当网络中不存在乱序数据包时,改进协议可以获得类似于标准TCP协议的吞吐量,保证对标准TCP协议的友好性.仿真实验表明,在网络中存在乱序数据包的情况下,改进后的TCP算法可以获得较标准TCP协议更高的网络吞吐量,而在无乱序数据包的情况下,改进协议仍具有很好的公平性和友好性.

| Abstract: | The mobility of nodes in mobile ad hoc networks(MANET) will result in lots of disordered data packets at receiving end,thus degrading the performance of TCP protocol.A new protocol(TCP-D) was proposed to improve the performance of TCP in MANET via the congestion control algorithm with trigger response delayed for a short time.The analysis of the response delayed TCP protocol showed that if no disordered packets in MANET,its steady state throughput is similar to that implemented according to standard TCP,thu... |
