延迟容忍网络路由协议综述

A Survey of Delay Tolerant Networks Routing Protocols

Zhenxin Feng, Kwan-Wu Chin

摘要:

微机电系统(MEMS)的进步已经彻底改变了数字时代,使有生命和无生命的物体都可以用作通信通道。此外,移动电话的普遍存在以及不断增加的功能和充足的资源意味着人们现在实际上是移动传感器,可以用来感知环境以及数据载体。这些对象及其设备形成了一种新的网络,其特征是频繁断开连接,资源限制和不可预测或随机的移动模式。这些网络的一个关键基础是路由或数据传播协议,这些协议是专门为处理上述特征而设计的。因此,有必要审查最先进的路由协议,对它们进行分类,并在传输速率、资源消耗和端到端延迟方面比较和对比它们的方法。为此,本文回顾了63单播,组播和编码为基础的路由协议,专门设计运行在延迟容忍或挑战的网络。我们提供了一个广泛的定性比较的所有协议,突出他们的实验设置和概述他们的设计和研究方法论方面的不足之处。除此之外,我们回顾研究,旨在利用社交网络和流行病学的研究,以提高路由协议的性能。最后,我们提出了未来的研究方向。

英文摘要:

Advances in Micro-Electro-Mechanical Systems (MEMS) have revolutionized the digital age to a point where animate and inanimate objects can be used as a communication channel. In addition, the ubiquity of mobile phones with increasing capabilities and ample resources means people are now effectively mobile sensors that can be used to sense the environment as well as data carriers. These objects, along with their devices, form a new kind of networks that are characterized by frequent disconnections, resource constraints and unpredictable or stochastic mobility patterns. A key underpinning in these networks is routing or data dissemination protocols that are designed specifically to handle the aforementioned characteristics. Therefore, there is a need to review state-of-the-art routing protocols, categorize them, and compare and contrast their approaches in terms of delivery rate, resource consumption and end-to-end delay. To this end, this paper reviews 63 unicast, multicast and coding-based routing protocols that are designed specifically to run in delay tolerant or challenged networks. We provide an extensive qualitative comparison of all protocols, highlight their experimental setup and outline their deficiencies in terms of design and research methodology. Apart from that, we review research that aims to exploit studies on social networks and epidemiology in order to improve routing protocol performance. Lastly, we provide a list of future research directions.
