在过去的十年中，政府、市政当局和行业投入了大量资金用于智慧城市的研究，其主要目标是开发服务以改善人们的生活质量。许多提案都集中在以云为中心的网络架构上，其中从传感器设备的amyriad收集的所有数据都被传输到云进行处理。然而，当面对物联网产生的巨大流量和对低延迟服务的需求时，这种方法存在重大局限性。物联网设备以紧凑的组部署，通过相对强大的“网关”连接到智能城市网络基础设施，打开了脱离集中式架构并将计算更接近数据源的可能性。为此，本文提出了SPF，一种新的中间件解决方案，支持物联网应用和服务的开发，部署和管理。SPF在位于网络边缘的有能力的设备上运行物联网服务，并提出了一种编程模型，可以无缝地利用分散的计算资源。SPF还利用为受限网络环境设计的信息传播解决方案，并采用基于信息价值的方法来优先传输重要信息。
In the last decade, governments, municipalities, and industries have invested large amounts of funds on research on smart cities with the main goal of developing services to improve people’s quality of life. Many proposals focus on a Cloud-centric network architecture in which all the data collected from amyriad of sensors devices is transferred to the Cloud for processing. However, this approach presents significant limitations when faced with the formidable traffic generated by the Internet of Things and with the need for low-latency services. The deployment of IoT devices in compact groups, connected to the smart city network infrastructure by relatively powerful “gateways”, opens the possibility to depart from the centralized architectures and move the computation closer to the data sources. To this end, this paper proposes SPF, a new middleware solution that supports IoT application and service development, deployment, and management. SPF runs IoT services on capable devices located at the edge of the network and proposes a programming model that enables to take advantage of decentralized computation resources in a seamless fashion. SPF also leverages an information dissemination solution designed for constrained network environments and adopts Value-of-Information based methods to prioritize transmission of essential information.
