摘要： 传统的TCP是为有线网设计的，研究TCP在Ad hoc网络中的性能，是改进TCP以适应Ad hoc网络的前提。在移动Ad hoc网络中，通过大量仿真实验比较了多个TCP版本在AODV和OLSR下对于不同移动模型的性能表现，包括有效吞吐率、端到端延迟、丢包率等，为改进TCP提供了依据。

Abstract: As originally designed for wired networks, TCP does not work well in Ad hoc networks. For improving it to fit the Ad hoc networks, TCP performance evaluation is the first priority. This paper proposes the evaluation and comparison of some TCP variants performance using AODV and OLSR in several mobility models in Ad hoc networks. The metric parameters include goodput, end to end delay and drop rate. Simulations provides a basis for the improvement of TCP.

Key words: Ad hoc networks, mobile model, performance
