A Home Area Network (HAN) is considered to be a significant component of Advanced Metering Infrastructure (AMI) and has been studied well in many works. It binds all the electrical components installed in a defined premise together for their close monitoring and management. However, HAN has been realized so far mostly as a centralized system. Therefore, like any other centralized system, the traditional realization of HAN also suffers from various well-known problems, such as single-point-of-failure, susceptibility to attacks, requirement of specialized infrastructure, inflexibility to easy expansion, etc. To address these issues, in this work, we propose a decentralized design of HAN. In particular, we propose an IoT based design where instead of a central controller, the overall system operation is controlled and managed through decentralized coordination among the the electrical appliances. We leverage Synchronous-Transmission (ST) based data-sharing protocols in IoT to accomplish our goal. To demonstrate the efficacy of the proposed decentralized framework, we also design a real-time intra-HAN load-management strategy and implement it in real IoT-devices. Evaluation of the same over emulation platforms and IoT testbeds show upto 62% reduction of peak load over a wide variety of load profiles.
BlendSM-DDM: BLockchain-ENabled Secure Microservices for Decentralized Data Marketplaces
为了促进物联网(IoT)在智能社区和智能城市中的优势,最近提出了一种称为智能物联网集成器(I3)的实时数据市场中间件平台。在通过市场促进设备所有者和第三方应用程序之间轻松交换实时物联网数据流的同时,I3目前是一个单一社区的单片集中式平台。虽然面向服务的架构(SOA)已经在物联网和网络物理系统(CPS)中被广泛采用,但是对于单一架构来说,难以为大量分布式物联网设备和不同应用供应商提供可伸缩、互操作和可扩展的服务。传统的安全解决方案依赖于集中的权威机构,这可能是性能瓶颈或容易出现单点故障。受容器化微服务和区块链技术的启发,本文提出了一种Blockchain-Enabled Secure Microservices for Decentralized Data Marketplaces(BlendSM-DDM)。在许可的区块链网络中,引入了基于微服务的安全机制,以保护市场参与者之间的数据交换和支付。BlendSM-DDM能够为数据市场提供分散,可扩展和可审计的数据交换。
