Collaborative Research: NeTS:WN : Coping with Jamming Attacks in Ad hoc / Mesh Networks

防止干扰攻击对于成功部署ad hoc或mesh网络至关重要。该项目的目标是从整体上考虑干扰问题，并设计一个框架来应对这些攻击。该框架将统一威慑、探测和减轻干扰效果的功能。与以前的努力不同，这项研究将（a）利用物理层的能力，如功率/速率的可调谐性和使用智能天线，以科普干扰和（B）设计解决方案，是基于强大的实验基础。此外，该设计将寻求解决不仅来自外部对手的干扰攻击，而且来自发送大量看似合法数据的内部受损节点的干扰攻击。该项目将包括以下任务：㈠进行广泛的实验，以了解干扰的影响，并确定干扰攻击期间的行为特征。(ii)设计方法来混淆流量模式，使干扰机将无法瞄准网络中的重要节点或位置（iii）在检测干扰攻击的框架设计中使用实验技术（iv）利用物理层功能（如速率/功率和智能天线）来科普攻击。这项研究预计将广泛影响未来成功部署的车辆和市政ad hoc/mesh网络。它还将与教育计划紧密结合，这些计划将增强无线教学实验室，并引入跨学科课程，以连接物理层和更高层。

Prevention of jamming attacks is critical to the successful deployment of ad hoc or mesh networks. The objective of this project is to consider the problem of jamming in a holistic way and design a framework towards coping with these attacks. The framework will unify the functionalities of deterring, detecting, and alleviating the effects of jamming. Unlike previous efforts this research will (a) exploit physical layer capabilities such as the tunability of power/rate and the use of smart antennas to cope with jamming and (b) design solutions that are based on strong experimental foundation. Furthermore, the design will seek to address jamming attacks by not only external adversaries but also internally compromised nodes that send large volumes of seemingly legitimate data. The project will encompass the following tasks: (i) Extensive experiments to understand the impact of jamming and identification of behavioral traits during a jamming attack. (ii) Design of methods to obfuscate traffic patterns such that the jammer will be unable to target important nodes or locations in the network (iii) Use of the experimental knowhow in the design of the framework for detecting jamming attacks and (iv) Exploiting physical layer capabilities such as rate/power and smart antennas to cope with attacks. This research is expected to broadly impact successful future deployments of vehicular and municipal ad hoc/mesh networks. It will also be tightly knit with educational programs that will augment wireless teaching laboratories and introduce cross-disciplinary courses that bridge the physical and higher layers.
