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

防止干扰攻击是成功部署自组网或网状网的关键。该项目的目标是以整体的方式考虑干扰问题，并设计一个应对这些攻击的框架。该框架将统一威慑、检测和缓解干扰影响的功能。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/速率的可调性和使用智能天线来应对干扰，以及(B)设计基于坚实的实验基础的解决方案。此外，该设计将寻求解决不仅来自外部对手的干扰攻击，还包括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：(I)广泛的实验，以了解干扰的影响和确定干扰攻击期间的行为特征。(Ii)设计混淆通信量模式的方法，使干扰器无法将网络中的重要节点或位置作为目标；(Iii)在设计检测干扰攻击的框架时使用实验技术；以及(Iv)利用物理层能力，如速率/功率和智能天线来应对攻击。这项研究预计将广泛影响未来车载和市政自组织/网状网络的成功部署。它还将与教育项目紧密结合，这些项目将加强无线教学实验室，并引入跨学科课程，架起物理和更高层的桥梁。

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.
