Multi-hop ad hoc networks may employ cooperative communication, in which opportunistic relays use the spatial diversity of radio channels to increase communication reliability. An emerging variant of traditional relaying and forwarding schemes is the lossy forwarding and joint decoding (LF-JD) concept. In theory, LF-JD has shown the potential to improve spectral efficiency, reduce transmit power, and decrease outage probability by exploiting route diversity and the broadcast nature of radio transmissions. To be applied in real devices, a lower-layer protocol stack embracing the LF-JD concept needs to be designed. In this article, we show how LF-JD impacts the design of MAC and routing protocols and whether its benefits translate to performance improvements. We show that, in comparison to currently available solutions, LF-JD can provide gains in scenarios with high interference or poor signal strength such as in V2V networks.

有损转发对无线自组织网络中 MAC 和路由设计的影响



多跳自组织网络可以采用协作通信,其中机会中继使用无线电信道的空间分集来提高通信可靠性。传统中继和转发方案的一个新兴变体是有损转发和联合解码(LF-JD)概念。理论上,LF-JD 已显示出通过利用路由分集和无线电传输的广播性质来提高频谱效率、降低发射功率和降低中断概率的潜力。为了在实际设备中应用,需要设计一个包含 LF-JD 概念的底层协议栈。在本文中,我们将展示 LF-JD 如何影响 MAC 和路由协议的设计,以及它的好处是否会转化为性能改进。我们表明,与当前可用的解决方案相比,LF-JD 可以在干扰高或信号强度差的场景(例如 V2V 网络)中提供增益。
