摘要： 对进入无线自组网节点的TCP数据流进行漏桶管制，节点为TCP提供基于速率-延迟模型的服务保障，在已有无线自组网链路吞吐量模型的基础上利用网络演算理论推导TCP数据流的吞吐量上界模型。在网格拓扑的无线自组网环境下，TCP数据流的仿真结果都在数值计算的上界范围内，从而表明基于网络演算的无线自组网TCP吞吐量性能上界模型具有较好的性能，同时也表明现有TCP协议在无线环境下还存在较大的改进空间。

Abstract: The data flow entering the node is regulated by leaky bucket, and the node provided rate-latency service for the flow. It has derived the TCP throughput upper bound for wireless Ad Hoc network based on the existing link throughput model using network calculus theory. For grid topology wireless Ad Hoc network, all simulated results for different data flows are bounded by theoretical results. These show the TCP throughput upper bound model performs well and the wireless TCP still needs more improvements.
