探讨了用仿真工具OPNET来研究语音分组在无线Ad Hoc网络传输特性。通过用OPNET网络仿真工具分析了三种不同场景下,语音分组在无线Ad Hoc网络中传输质量的变化,及对三个不同场景下语音分组传输质量进行了分析比较,得到一些有用的结论,如:验证了用OPNET仿真工具研究无线Ad Hoc网络语音传输特性的有效性和可行性;在无线Ad Hoc网络中,随着跳数的增加,语音传送质量会随着跳数的增加而变差等有用结论。
The simulation tool OPNET is used to study the transmission characteristics of voice packets in wireless Ad Hoc networks. By using OPNET network simulation tools to analyze the three different scenarios, voice packets in wireless Ad Hoc network transmission quality changes, and three different scenarios voice packet transmission quality analysis and comparison, get some useful conclusions, such as : Verifies the validity and feasibility of using OPNET simulation tools to study the voice transmission characteristics of wireless Ad Hoc networks. In wireless Ad Hoc networks, as the number of hops increases, the voice transmission quality deteriorates with the increase of hop count Useful conclusion.
