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.

为了在关键情况下使用无人看管的无线传感器网络（WSN），它们必须能够在敌对环境中长时间运行。因此，WSN的协议必须能节能。除了对能源效率的需求外，部署在敌对区域中的WSN也应具有弹性。当前防御恶意威胁的方法是为特定攻击开发和部署特定的防御机制。但是，这种不切实际的假设只有准备传感器的攻击才能执行。为了真正实现任务关键传感器网络，WSN必须具有防御所有已知攻击的能力，以及防御未来攻击的机制（即WSN必须是自我保护）。该提案解决了实施大规模自我保护的WSN的挑战和可行性。特别是，该提案旨在确定是否存在：1）当前传感器系统体系结构存在基本局限性，以阻止实现自我保护的WSN； 2）当前的网络协议和数据库技术可以提供基于约束的路由以及自我保护WSN所需的实时存储 /检索； 3）自我保护WSN的拟议架构本身容易受到攻击。在必要时，项目还在项目中开发了克服当前体系结构和协议的潜在局限性的算法和体系结构。
