军事、治安、抢险等特殊领域在无通信基础设施情况下对语音通信有着迫切需求.通过结合Ad Hoc网络、嵌入式系统、多媒体开发技术完成了一套具有控制中心和Ad Hoc嵌入式终端的语音通信系统.通过将基于稳定链路的路由选择与RTP实时传输相结合,有效控制了系统的时延和抖动,保证了语音通信系统的语音传输质量.实地测试实验表明,该系统易于构建、移动适应性强,语音通信话音基本流畅,性能稳定,满足设计需求.
There is an urgent need for voice communications in special areas such as military, law and order, and emergency rescue without the use of communication infrastructure. By combining Ad Hoc networks, embedded systems and multimedia development technologies, a set of voice control centers and Ad Hoc embedded terminals have been completed Communication system.Through the combination of stable link routing and RTP real-time transmission, the system’s delay and jitter are effectively controlled to ensure the voice transmission quality of the voice communication system.Field experiments show that the system is easy to construct and move Strong adaptability, basic voice communication voice flow, stable performance, to meet the design needs.
