无线网络中差错控制与拥塞控制策略的分析

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。鉴于网络中的差错控制和拥塞控制是网络通信性能优劣的重要基础和前提。为此，分析和探讨了适用无线网络的差错控制与拥塞控制策略，讨论了当前在这方面的研究动向，为以后的进一步研究提供了重要的参考。

Analyses & Considerations about the Policies of Error Controls and Congestion Controls in Wireless Networks

Compared with wire networks, the wireless environments have many different characteristics 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 hard to be guaranteed. Based on the importance of error controls and congestion controls to network's performance, the policies of error controls and congestion controls in wireless networks are primarily analyzed and discussed in this paper, and some trends are also presented, which can give some valuable references for further studies.
