多跳无线网络中的通用路由

Universal Routing in Multi-hop Radio Networks

Bogdan S. Chlebus, Vicent Cholvi, Dariusz R. Kowalski

摘要:

在这篇文章中,我们介绍了一个新的模型来研究在多跳无线网络的对抗性路由的框架中的稳定性。在这样的模型中,路由协议由三个部分组成:传输策略,从一组驻留在节点的数据包中选择要传输的数据包的调度策略,以及协调传输与调度的侦听控制机制。对于这样的设置,我们提出了一个普遍的稳定性的定义,不仅考虑到调度策略(如在标准的有线对抗模型),但也传输策略。首先,我们表明,在经典的有线对抗模型中不稳定的任何调度策略在多跳无线电网络模型中仍然不稳定,即使在没有干扰的情况下也是如此。然后,我们表明,SIS和LIS(两个众所周知的普遍稳定的调度策略,在有线对抗模型)保持稳定的多跳无线电网络模型,提供了一个积极的听力控制。相比之下,这样的调度策略在使用反应性听力控制时变得不稳定。然而,调度策略LIS可以被强制为普遍稳定的,只要以永久的方式解决关系。这种情况在SIS的情况下并不存在,无论关系如何解决,SIS仍然不稳定。此外,对于一些传输策略,我们称之为定期,我们还表明,所有的调度策略,普遍稳定时,使用主动听力控制(其中包括SIS和LIS)仍然普遍稳定时,使用反应性听力控制。

英文摘要:

In this article we introduce a new model to study stability in multi-hop wireless networks in the framework of adversarial queueing. In such a model, a routing protocol consists of three components: a transmission policy, a scheduling policy to select the packet to transmit form a set of packets parked at a node, and a hearing control mechanism to coordinate transmissions with scheduling. For such a setting, we propose a definition of universal stability that takes into account not only the scheduling policies (as in the standard wireline adversarial model), but also the transmission policies. First, we show that any scheduling policy that is unstable in the classical wireline adversarial model remains unstable in the multi-hop radio network model, even in scenarios free of inter- ferences. Then, we show that both SIS and LIS (two well-known universally stable scheduling policies in the wireline adversarial model) remain stable in the multi-hop radio network model, provided a proactive hearing control is used. In contrast, such scheduling policies turn out to be unstable when using a reactive hearing control. However, the scheduling policy LIS can be enforced to be universally stable provided ties are resolved in a permanent manner. Such a situation doesn't hold in the case of SIS, which remains unstable regardless of how ties are resolved. Furthermore, for some transmission policies which we call regular, we also show that all scheduling policies that are universally stable when using proactive hearing control (which include SIS and LIS) remain universally stable when using reactive hearing control.
