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

无线技术在今天已经变得不可或缺。年代的世界。然而，干扰攻击是一个突出的问题，由于链路质量的显著下降，导致网络可用性丧失，延迟增加和吞吐量降低。用户和干扰者之间的相互作用是博弈论分析的自然选择，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者对无线网络稳定性和福利的影响程度。该项目模拟了本地干扰器对更高级别网络功能（如交通流量和拥塞）的影响。pi提供公式并解决物理层和网络层的零和和其他游戏，这些游戏反映了适当的效用/成本函数，干扰机和收发器资源约束和常识（例如关于信道条件的侧信息）。利用算法博弈论的指标，如稳定/无政府状态的价格，将开发新的指标和分析技术来衡量干扰的影响，如干扰的价格，它衡量当干扰者参与时，平衡会变得多么糟糕。pi还研究了导致矛盾情况（干扰悖论）的网络、游戏和效用函数的存在，其中干扰者实际上可能提高系统的福利。因此，这项工作将为确定无线网络中干扰损害的程度以及设计适当的抗干扰机制提供广泛的见解。这项研究的成果将通过出版物、讲座和课程进行传播。在pi研究小组中，传统上代表性不足的少数民族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.
