机载网络连通性研究

On Connectivity of Airborne Networks

Shahrzad Shirazipourazad, Pavel Ghosh, Arunabha Sen

摘要:

移动网络中节点的移动模式对网络的连通性有重要影响。在过去的几年中,一个这样的移动网络引起了研究人员的注意,是机载网络(AN),由于其在民用和军事目的的重要性,并由于在这些领域中的几个复杂的问题。由于机载网络(AN)中的节点是异构的和移动的,一个可靠的和鲁棒的AN的设计是非常复杂和具有挑战性的。在本文中,一个持久的骨干网为基础的体系结构的AN已被认为是一组机载网络平台(ANPs -飞机,无人机和卫星)形成的AN的骨干。骨干节点的端到端连接性对于提供主机之间的通信至关重要。由于ANP容易因为EMP攻击或干扰等攻击而失败,另一个重要的问题是提高骨干网络对这些攻击的鲁棒性。这种攻击将在特定时间影响特定的地理区域,并且如果ANP在攻击期间处于故障区域内,则它将失败。本文重点研究了网络的连通性和容错性问题,并研究了在无故障和故障情况下计算网络最小传输距离的算法,以保证网络始终保持连通性。它还考虑了网络可能必须在一段时间内以断开模式操作并且数据传输可能容忍一定量的延迟的情况。因此,ANP可能不需要始终具有端到端路径,但它们应该能够在有限的时间内相互传输数据。

英文摘要:

Mobility pattern of nodes in a mobile network has significant impact on the connectivity properties of the network. One such mobile network that has drawn attention of researchers in the past few years is the Airborne Networks (AN) due to its importance in civil and military purpose and due to the several complex issues in these domains. Since the nodes in an airborne network (AN) are heterogeneous and mobile, the design of a reliable and robust AN is highly complex and challenging. In this paper a persistent backbone based architecture for an AN has been considered where a set of airborne networking platforms (ANPs - aircrafts, UAVs and satellites) form the backbone of the AN. End to end connectivity of the backbone nodes is crucial in providing the communication among the hosts. Since ANPs are prone to failure because of attacks like EMP attack or jamming, another important issue is to improve the robustness of the backbone network against these attacks. Such attacks will impact specific geographic regions at specific times and if an ANP is within the fault region during the time of attack, it will fail. This paper focuses on connectivity and fault-tolerance issues in ANs and studies algorithms to compute the minimum transmission range of ANPs in fault free and faulty scenarios to ensure network connectivity all the times. It also considers the scenario where the network may have to operate in a disconnected mode for some part of time and data transmissions may be tolerant to some amount of delay. Hence, ANPs may not need to have end-to-end paths all the time but they should be able to transmit data to each other within bounded time.
