EAGER: Evaluating the feasibility of Self-Protecting Heterogeneous Wireless Sensor Networks

为了在关键情况下使用无人值守的无线传感器网络(WSN)，它们必须能够在恶劣的环境中长时间工作。因此，无线传感器网络的协议必须是节能的。除了能源效率的需要，部署在敌对地区的无线传感器网络还应该具有抵御攻击的能力。当前防御恶意威胁的方法是针对特定攻击开发和部署特定的防御机制。然而，这不切实际地假设只有传感器准备好的攻击才会执行。为了真正实现任务关键型传感器网络，无线传感器网络必须具有抵御所有已知攻击的能力以及防御未来攻击的机制(即，无线传感器网络必须具有自我保护功能)。这项建议解决了实施大规模自我保护无线传感器网络的挑战和可行性。特别是，该方案试图确定：1)当前传感器系统体系结构是否存在根本限制，阻碍了自保护WSN的实现；2)当前的网络协议和数据库技术能够提供自保护WSN所需的基于约束的路由和实时存储/检索；以及3)所提出的自保护WSN体系结构本身容易受到攻击。在必要时，该项目还开发了克服当前体系结构和协议的潜在限制的算法和体系结构。

For the use of unattended wireless sensor networks (WSNs) in critical situations to be viable, they must be able to operate in hostile environments for extended periods of time. Therefore, protocols for WSNs must be energy-efficient. In addition to the need for energy-efficiency, a WSN deployed in a hostile region should be resilient to attack. The current approach to defending against malicious threats is to develop and deploy a specific defense mechanism for a specific attack. However, this unrealistically assumes that only the attack that the sensor is prepared for will be executed. To truly realize mission critical sensor networks, the WSN must have the capability to defend against all known attacks as well as mechanisms for defending against future attacks (i.e., the WSN must be self-protecting). This proposal addresses the challenges with and feasibility of implementing large-scale self-protecting WSNs. In particular, this proposal seeks to determine if: 1) there are fundamental limitations of current sensor system architectures that prevent the realization of a self-protecting WSN; 2) the current network protocols and database techniques can provide the constraints-based routing and real-time storage / retrieval required for self-protecting WSNs; and 3) the proposed architecture of the self-protecting WSN is itself susceptible to attack. Where necessary, algorithms and architectures to overcome the potential limitations of current architectures and protocols are also developed in the project.
