机器人应用中无线网络完全确定性介质访问方法的提出

Proposition of a full deterministic medium access method for wireless network in a robotic application

Adrien Van Den Bossche, Thierry Val, Eric Campo

摘要:

今天,许多网络应用程序需要更短的反应时间。机器人领域是这些需求的一个很好的例子:机器人的反应时间对其任务的复杂性有直接的影响。在这里,我们提出了一个完整的确定性介质访问方法的无线机器人应用程序。这种贡献是基于一些低功耗的无线个域网,如ZigBee标准。实际上,ZigBee已经识别出由于非确定性介质接入和介质预留请求期间的可能冲突而导致的服务质量的限制。在本文中,提出了两个主要的改进:一个有效的轮询的星型节点和时间确定性分布的对等消息。这种新的无冲突的MAC协议提供了一些QoS能力。

英文摘要:

Today, many network applications require shorter react time. Robotic field is an excellent example of these needs: robot react time has a direct effect on its task's complexity. Here, we propose a full deterministic medium access method for a wireless robotic application. This contribution is based on some low-power wireless personal area networks, like ZigBee standard. Indeed, ZigBee has identified limits with Quality of Service due to non-determinist medium access and probable collisions during medium reservation requests. In this paper, two major improvements are proposed: an efficient polling of the star nodes and a temporal deterministic distribution of peer-to-peer messages. This new MAC protocol with no collision offers some QoS faculties.
