Description: 针对TCP (Transmission Control Protocol) 协议在高速卫星因特网中传输吞吐量低的问题, 提出了一种改
进TCP快速恢复的算法。该算法根据卫星信道由传输错误造成的分组丢失概率远大于由拥塞造成的分组丢失
概率的特点, 通过加快窗口的增长速度, 避免过早地进入拥塞避免阶段, 达到了提高TCP吞吐量的目的。通
过NS2软件模拟仿真了高速卫星因特网环境, 并对各个TCP版本和改进算法的仿真结果进行了比较和分析。
仿真结果表明, 改进算法的吞吐量比TCP2SACK提高了约10 , 比TCP2Reno提高了约30 。-A new algorithm is p roposed to imp rove the throughput of high speed satellite&internet network. In
satellite channels, most of lost package is due to transmission error instead of congestion. We can make some im2
p rovement on TCP (Transmission Control Protocol) fast recovery algorithm. Bymaking the window increase fas2
ter and not enter congestion avoidance too early. We imp rove the throughput of TCP. We use NS2 to simulate the
environment of satellite and internet network, and the results are compared. In simulation, about 10 through2
put in our algorithm is imp roved than TCP2SACK, and that is about 30 imp roved than TCP2Reno.

Description: Implementing a New Manet Unicast Routing Protocol in NS2. PDF Development Research. During the last year, we have witnessed a lot of people asking for the same
question in the ns-users mailing list. How do I develop my own protocol for
NS2? By writing this document we hope to help those researchers who need to
add a manet routing protocol for NS-2.27. We focus our document in unicast
protocols. The document is aimed to those people who are somehow familiar
with performing simulations in ns-2, and they want to go one step forward to
implement their own protocols. Everything we describe in this text is related
to version 2.27 of NS2, but it might be useful for other versions as well. Platform: |

Description: The sensor networks application domain continues to increase with the need for an
effective security mechanism. The fact that WSN often deal with sensitive data operating in
hostile and unexpected environments, makes the concept of security considered essential.
However, because of limited resources and low computing capacity of a sensor node, the
development of a mechanism that ensures security is a real design challenges.
In this report we have tried to propose a new security mechanism dedicated to WSN. Our
main objective is to secure the process of transferring data to the base station. The proposed
protocol protects transferred data against intruder nodes attacks, using a security
mechanism based on the use of control message MAC (Message Authentication Code) for
authentication. Our protocol performances are evaluated using the simulator NS2. Platform: |

Description: 本文着重研究网络中使用的MAC协议对语音传输过程的影响，以及无线传
感器网络中适用的语音编码算法。本文首先综述了现有无线传感器网络中常用
的MAC协议，对这些协议进行了分析比较。提出了一种新的基于TDMA的MAC
协议VR-TDMA，为了测试提出的协议性能，在NS2仿真平台上对该协议进行
了仿真，结果证明该协议具有良好的实时性能。然后研究了几种常用语音编码
算法的性能，通过比较研究，认为ADPCM语音编码算法的性能符合无线传感
器网络应用的要求，并对该算法进行了简化，减少了算法运行的计算量。实际
测试表明，算法具有良好的性能。

Moreover we analyse and make comparison of them．Secondly，we propose a new
mac protocol named VR-TDMA．Simulation in NS2 proves that this protocol Canhave pleasing performance in real．time application．Thirdly,we
make a comparison
of some famous speech encoders．The result indicates that ADPCM(Adaptive
Di脏rential Pulse Code Modulation)is simpler than advanced low bit。rate VOICe
coding techniques and doesn’t require as heavy caculations．In this work，We simplify
the algorithm in order tO make it fit for the networks beaer．Actual tests prove that
this simplified algorithm work well in wireless sensor networks． Platform: |

Description: We assume that the reader is familiar with the NS2 basics. That means having
read and at least mostly understood “Marc Greis’ Tutorial” [1]. It would be
very useful if you also take a look at “The ns Manual” [2], specially chapters 3-5,
10-12, 15-16, 23, 25 and 29. We will refer to them several times throughout this
text and encourage you to read them. Before coding your own routing protocol,
you should know how to perform simulations with other implemented protocols
and you are expected to feel familiar and comfortable with simulator. This will
avoid lots of misunderstandings and doubts while reading this document.
