FRESNEL: FedeRatEd Secure sensor NEtwork Laboratory

无线传感器网络越来越多地被视为大规模跟踪和监控应用的解决方案。然而，这些网络的部署和管理由中央控制实体处理，并且传感器网络通常专用于单个应用。我们认为，这是因为我们还没有办法处理一个安全的多用途联合传感器网络，并行运行不同的应用程序，并且能够动态地重新配置以运行其他应用程序。通常为小型和单一所有者的传感器网络设计的通信范例不具备这种环境所需的适当的可扩展性、安全性和可重构性特征。我们希望确保可靠的应用程序内部通信以及可扩展的分布式管理基础设施。从正交性的角度来看，隐私和应用安全也应该得到维护。我们通过在剑桥校园建立大规模的传感器网络联盟来评估我们的方案。传感器监控不同的方面(温度、污染、移动等)，网络将运行属于城市不同当局的各种应用程序。

Wireless sensor networks are more and more seen as a solution to large-scale tracking and monitoring applications. The deployment and management of these networks, however, is handled by a central controlling entity and the sensor network is often dedicated to a single application. We argue that this is due to the fact that we do not yet have the means to deal with a secure multi-purpose federated sensor network, running different applications in parallel and able to reconfigure dynamically to run others.The communication paradigms which have been usually devised for small and single owner sensor networks simply do not have the right scalability, security, reconfigurability characteristics required for this environment.With FRESNEL we aim to build a large scale federated sensor network framework with multiple applications sharing the same resources. We want to guarantee a reliable intra-application communication as well as a scalable and distributed management infrastructure. Orthogonally, privacy and application security should also be maintained.We evaluate our proposal though a large scale federation of sensor networks over the Cambridge campus. The sensors monitor different aspects (temperature, pollution, movement, etc) and the network will be running various applications belonging to different authorities in the city.
