摘要

即将到来的新一代无线网络非常强调对高可靠性的要求。然而,在这些和其他网络方面(主要是延迟和带宽)之间进行权衡是一个持续的优化问题,也是一个艰巨的挑战。所采用的各种协议增加了一定的封装开销,尽管这是必要的,但可能会过多,例如在各种物联网的情况下,以及具有小有效载荷的类似应用程序。报头压缩的目标是减少这些报头,但是一个普遍的问题仍然困扰着标准,因为他们引入了易丢失的无线网络,这是丢失上下文(重新)初始化数据包的问题,它可以使压缩启动和传输的主要变化不可靠,缓慢和昂贵。在本文中,我们提出了一种解决方案,通过使用网络编码来规避传统报头压缩上下文初始化的一些问题,我们称之为可靠基础提议技术。这提供了一个很好的可调方法来平衡可靠性和延迟的解压缩与带宽增益。我们的结果表明,与以前的标准相比,压缩增益和可靠性都有所提高。

Reliable Base Proposal for Header Compression
The upcoming wireless network generation has put a large emphasis on the fulfilment of high reliability constraints. Nonetheless, the trade- off between these and other network aspects, mainly delay and bandwidth, is a constant optimisational question and a tough challenge. The various employed protocols add certain encapsulation overheads, which albeit necessary, however could potentially be excessive, such as in the case of various IoT, and similar applications with small payloads. Header compression aims to reduce these headers, but a general problem still plagues the standards since their introduction to loss-prone wireless networks, which is the issue of lost context (re)initialisation packets that can make the compression upstart and the transmission of major changes unreliable, slow and costly. In this paper we propose a solution that circumvents some concerns of traditional header compression context initialisation by the employment of network coding, which we call the reliable base proposal technique. This provides a finely tunable method for balancing reliability and delay of decompression with bandwidth gain. Our results show that both compression gain and reliability can be increased over the previous standards.
