Abstract

The operation of TCP in wireless/mobile environments is considered. After briefly presenting previous efforts to ameliorate TCP performance in the considered environments, we propose a new mechanism for tackling the problems caused by handovers. Our mechanism is based on stochastic datagram relocation. Traffic destined to the mobile terminal is tunneled to adjacent cells according to the output of a path prediction algorithm. To reduce the associated overhead, only percentages of inbound traffic are copied to the cell's neighborhood on the basis of estimated probabilities. Through simulations, we have measured the effects that stochastic datagram relocation has on TCP dynamics.
无线/移动通信中的TCP性能增强
考虑了TCP在无线/移动环境中的操作。在简要介绍了以前在考虑的环境中改善TCP性能的努力之后,我们提出了一种解决由移交引起的问题的新机制。我们的机制是基于随机数据报重定位。根据路径预测算法的输出,将到达移动终端的流量隧道到相邻的小区。为了减少相关的开销,根据估计的概率,只有一定比例的入站流量被复制到单元的邻域。通过仿真,我们测量了随机数据报重定位对TCP动态的影响。
