FRESNEL: FedeRatEd Secure sensor NEtwork Laboratory

无线传感器网络越来越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是由中央控制实体处理的，传感器网络通常专用于单个应用程序。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传感器网络设计的通信范式根本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。通过FRESNEL，我们的目标是建立一个大规模的联邦传感器网络框架，使多个应用共享相同的资源。我们希望保证可靠的应用内部通信以及可扩展的分布式管理基础设施。此外，还应维护隐私和应用程序安全性。我们通过剑桥校园的大型传感器网络联盟来评估我们的建议。传感器监测不同方面（温度、污染、运动等），网络将运行属于城市不同部门的各种应用程序。

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.
