Abstract

Being confronted with numerous MAC protocols designed under a variety of networking considerations, we envision a software-defined MAC controller that can be "re-configured" to different MAC protocols. This paper presents a unified algorithm for wireless MAC protocols - a pioneer trial of this vision that benefits future wireless networks. This unified algorithm is based on the concept of MULCAR, a generalized model for MAC protocols proposed by Chen and Sun. We observed that most protocols operate in a cycling fashion and identified major differences between each algorithm. Combining this with the concept of MULCAR, we unified several representative wireless MAC protocols into one parameterized algorithm. Among them are ALOHA with geometric backoff, binary exponential backoff and Q-ary collision resolution algorithm, p-persistent CSMA, CSMA/CA, and GRAP. One can thus have the unified algorithm operate as different MAC algorithms with proper parameter setting, which enables the development of the software-defined MAC controller.

无线MAC协议的统一算法

面对在各种网络考虑下设计的众多MAC协议，我们设想一个软件定义的MAC控制器，可以“重新配置”到不同的MAC协议。本文提出了一种无线MAC协议的统一算法，这是一种对未来无线网络有益的前瞻性试验。该统一算法基于MULCAR的概念，MULCAR是Chen和Sun提出的MAC协议的广义模型。我们观察到大多数协议以循环方式运行，并确定了每种算法之间的主要差异。结合MULCAR的概念，我们将几种具有代表性的无线MAC协议统一为一个参数化算法。其中包括几何退避的ALOHA、二进制指数退避和q元碰撞解决算法、p-persistent CSMA、CSMA/CA和GRAP。因此，可以通过适当的参数设置将统一算法作为不同的MAC算法运行，从而实现软件定义MAC控制器的开发。
