Abstract

Dedicated short range communication (DSRC) has been allocated (3 EU, 7 US) dedicated channels at 5.9GHz for vehicular communications. Although resource allocations on the Control Channel (CCH) reserved for safety-related applications have been well investigated, efficient usage of the other Service Channels (SCH) has attracted less attention. In this paper, we propose the design of an asynchronous multichannel mechanism for service management at 5.9GHz. Whereas the service phase defined in the IEEE WAVE standard requires vehicles to remain tuned on a given service channel, the proposed mechanism relies on cognitive principles to let service providers and users dynamically switch between channels and converge to a rendezvous channel where they can negotiate service support and conditions. The mechanism has been implemented on the ETSI compliant ITS simulation platform iTETRIS. We investigate the delay required to converge to such rendezvous channel and illustrate that an optimal cognitive parameter set manages to keep it within an acceptable range, and yet provides more flexibility to the channel usage.

短文:5.9GHz多通道车辆服务管理机制的设计与评估

专用短程通信(DSRC)已经分配(3个欧盟，7个美国)5.9GHz专用信道用于车辆通信。尽管控制通道(CCH)上为安全相关应用保留的资源分配已经得到了很好的研究，但其他服务通道(SCH)的有效使用却引起了较少的关注。在本文中，我们提出了一种用于5.9GHz业务管理的异步多通道机制设计。鉴于IEEE WAVE标准中定义的服务阶段要求车辆在给定的服务信道上保持调谐，所提出的机制依赖于认知原则，让服务提供商和用户在信道之间动态切换，并汇聚到一个集合信道，在那里他们可以协商服务支持和条件。该机制已在符合ETSI标准的ITS仿真平台iTETRIS上实现。我们研究了收敛到这种交会信道所需的延迟，并说明了一个最佳的认知参数集可以使其保持在可接受的范围内，同时为信道使用提供了更大的灵活性。
