Description: This documentation is based on the following versions:- pre-release of the wimax model developed by NIST (file patch-wimax-prerelease-092206)- ns-2.29
此程序是NS2下用C、C++编写的，主要对Wimax 802.16d和802.16e的MAC层协议的仿真，压缩文件内部有详细的说明。
由于NS2运行在Linux下而且是对网络的模拟，因此把它归在Linux/网络类中-This documentation is based on the followi Vi versions :- pre-release of the model developed by wimax NI ST (file patch-wimax- prerelease- 092206)- ns This procedure is-2.29 NS2 using C, C, prepared mainly right WiMAX 802.16d and 802.16e MAC layer protocol simulation, compressed files within the detail. As NS2 running under Linux is the network simulation, therefore it to the Linux/networking category 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。
-In this paper,we concentrate on the mac protocols of wireless sensor networks，
especially the impact imposed on speech transmition．We also want to find a speech
coder which is fit for wireless sensor networks．Firstly,we intorduce the existing mac
protocol，such aS IEEE802．1 1，SMAC protocol，TRAMA protocol，DMAC protoc01．
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: In last decades, the demand of wireless spectrum has
increased rapidly with the development of mobile communication
services. Recent studies recognize that traditional fi xed spectrum
assignment does not use spectrum effi ciently. Such a wasting
phenomenon could be amended after the present of cognitive
radio. Cognitive radio is a new type of technology that enables
secondary usage to unlicensed user. This paper presents an
Opportunistic Cognitive MAC Protocol (OC-MAC) for cognitive
radios to access unoccupied resource opportunistically and coex-
ist with wireless local area network (WLAN). By a primary traffi c
predication model and transmission etiquette, OC-MAC avoids
producing fatal damage to licensed users. Then a ns2 simulation
model is developed to evaluate its performance in scenarios with
coexisting WLAN and cognitive network.-In last decades, the demand of wireless spectrum has
