NeTS: Small: Modeling and Analysis of Multilayer Jamming Games in Wireless Networks

无线技术已经成为当今世界不可或缺的一部分--S。然而，拥塞攻击是一个突出的问题，由于链路质量的显著恶化，导致网络可用性损失、延迟增加和吞吐量下降。用户和干扰机之间的相互作用自然适合于博弈论分析，它为干扰问题提供了战略解决方案，并使我们能够研究干扰机对无线网络的稳定性和福利的影响程度。该项目模拟本地干扰器对更高级别网络功能(如流量和拥塞)的影响。PI在反映适当的效用/成本函数、干扰器和收发机资源约束以及共同知识(例如，关于信道条件的辅助信息)的物理层和网络层上提供公式并解决零和博弈和其他博弈。利用算法博弈论中的指标，如稳定/无政府状态的代价，将开发新的指标和分析技术来衡量干扰的影响，如干扰的代价，它衡量当涉及干扰器时，均衡可能会变得更差。PI还检查导致矛盾情况(干扰悖论)的网络、游戏和效用函数的存在，在这些情况下，干扰器实际上可以改善系统的福利。因此，这项工作将为确定无线网络中干扰破坏的程度以及设计适当的抗干扰机制提供广泛的见解。这项研究的结果将通过出版物、讲座和课程进行传播。PIS研究组中传统上代表人数较少的少数族裔学生将积极参与这项研究。

Wireless technology has become indispensible in today?s world. However, jamming attacks are a prominent problem, resulting in loss of network availability, increased latency and reduced throughput due to significant deterioration of link quality. The interplay between users and jammers is a natural fit for game-theoretic analysis which provides strategic solutions to the jamming problem and allows us to study the extent to which jammers affect the stability and welfare of the wireless network. This project models the impact of local jammers on higher level network functions such as traffic flows and congestion. The PIs provide formulations and solve zero-sum and other games at physical and network layers that reflect appropriate utility/cost functions, jammer and transceiver resource constraints and common knowledge (e.g. side information about channel conditions). Leveraging metrics from algorithmic game theory, such as the price of stability/anarchy, novel metrics and analytical techniques will be developed that measure the impact of jamming such as the Price of Jamming, which measures how much worse equilibria can get when jammers are involved. The PIs also examine the existence of networks, games and utility functions which lead to paradoxical situations (Paradox of Jamming), where jammers may actually improve the welfare of the system. Thus, this work will provide broad insights into determining the extent of jamming damage in wireless networks and also to design appropriate anti-jamming mechanisms. The outcomes of this research will be disseminated through publications, talks, and courses. Traditionally underrepresented minority students in the PIs research groups will actively participate in this research.
