Abstract

With the rapid advancement of wireless technology and the exponential increase of wireless devices in the past decades, there are more consumer applications for MANETs (mobile ad hoc networks) in addition to the traditional military uses. A resilient and robust MANET is essential to high service quality for applications. The dynamically changing topologies of MANETs pose a huge challenge to normal network operations. Furthermore, malicious attacks against critical nodes in the network could result in the deterioration of the network. In this paper, we employ several real-world human mobility traces to analyze network robustness in the time domain. We apply attacks against important nodes of the human topology and compare the impact of attacks based on different centrality measures. Our results confirm that nodes with high betweenness in a well-connected large dynamic network play the most pivotal roles in the communication between all node pairs.
基于人类移动轨迹的移动自组织网络鲁棒性分析
随着无线技术的快速发展和无线设备在过去几十年中呈指数级增长,除了传统的军事用途外,manet(移动自组织网络)还有更多的消费应用。弹性和健壮的MANET对应用程序的高服务质量至关重要。manet拓扑结构的动态变化对网络的正常运行提出了巨大的挑战。此外,针对网络关键节点的恶意攻击可能会导致网络性能的恶化。在本文中,我们使用几个真实世界的人类移动轨迹来分析网络在时域上的鲁棒性。我们将攻击应用于人类拓扑的重要节点,并基于不同的中心性度量比较攻击的影响。我们的研究结果证实,在连接良好的大型动态网络中,具有高中间性的节点在所有节点对之间的通信中起着最关键的作用。
