一种新的无线网络显式误码丢包指示机制及其分析讨论

无线应用的飞跃发展和广阔的应用前景，使得人们不得不把更多的目光投向无线网络的通信。由于无线环境与有线环境相比，具有误码率高、时延大、带宽低、信道不对称以及频繁的移动等特性，使无线网络中的通信质量难于保证。针对这一问题，提出了一种新的无线网络显式误码丢包指示机制，并对其进行了分析讨论。此机制实现简单，所增加的系统额外开销小，能有效地改善无线网络中的通信性能，具有明显的现实意义。

Presentation & Analysis and Discussion About a New Explicit Corruption Identification in Wireless Network

Communications in wireless network are being concerned greatly because of its rapid developments and rich futures. Comparing to wire networks, there are many different characteristics in wireless environments, such as higher error rate, longer delay, lower bandwidth, asymmetric channel, frequent mobility and so on, which makes the qualities of services in wireless network be hard to be guaranteed. Then a new explicit corruption identification mechanism for wireless networks is presented, analyzed and discussed in this paper. This mechanism can efficiently improve the communication performances in wireless networks and can be simply implemented, and the additional overheads are very small, which makes it have obvious value.
