摘要
IEEE802.11 DCF作为无线局域网的MAC层规范被广泛应用于无线自组织网络的仿真和测试中。通过研究发现即使在拓扑不变的条件下,使用表驱动路由协议DSDV,TCP流仍然存在不稳定和不公平现象,本文分析了问题产生的原因,提出了基于网络负载的解决问题方法。
The IEEE 802. 11 MAC protocol is the standard for wireless LANs, it is widely used in test-beds and simulations for wireless multi-hop ad hoc networks. Although it can support some ad hoc network architecture, it is not intended to support the wireless mobile ad hoc network. The simulations show that, given a specific network topology, using table driven router protocol DSDV, there still exit flows. In this article we reveal the causes of the problem unfairness problem and instability problem among the TCP and offer the possible solutions based on network overload.
