Abstract

For wireless systems, it is of vital importance to use the scarce radio resources in an efficient way. In a typical system, each layer adds its own header, resulting in prohibitive signaling overhead. Several header compression schemes have been proposed to reduce this overhead. All compression schemes must be kept simple to cope with high load. Unfortunately, existing compression schemes cover, each, no more than two layers taking advantage of header format knowledge. We propose a header compression scheme that can cover all layers, from the 802.11 MAC layer up to the Application layer, without required knowledge of the headers format. We compare our proposal to a general simple compression scheme, and show that our proposal processing time is 60% faster. We show that on average, in a typical scenario, with high SNR, we reduce the header overhead by 70 bytes.

通用全层结合高效WLAN MAC层报头压缩
对于无线系统来说,如何有效地利用稀缺的无线资源是至关重要的。在典型的系统中,每一层都添加了自己的报头,导致了令人望而却步的信令开销。已经提出了几种报头压缩方案来减少这种开销。所有压缩方案必须保持简单,以应对高负载。不幸的是,现有的压缩方案利用报头格式知识覆盖的层不超过两层。我们提出了一个报头压缩方案,它可以覆盖所有层,从802.11 MAC层到应用层,而不需要了解报头格式。我们将我们的提议与一般的简单压缩方案进行了比较,结果表明我们的提议处理时间快了60%。我们表明,平均而言,在一个典型的场景中,具有高信噪比,我们减少了70字节的报头开销。
