基于物联网标识的智能家居服务体系架构设计

目前,智能家居领域在互联互通方面主要存在两个问题：一个是家庭环境中多个设备之间无法实现较好的互联互通;另一个问题是智能家居系统所采用的标识、操作平台和编程语言没有统一的标准。异构的服务和设备需要彼此协作来共同执行任务。因此,设备和标识的异构性问题会导致智能家居系统的兼容性较差。本文提出了一种基于物联网标识的全新智能家居服务体系架构,明确了智能家居的各参与方及其之间的关系,设计了智能家居服务的具体流程。这种架构可以在对现有的智能家居产品不做额外改变的前提下,实现不同产品之间的互连互通,提高智能家居系统的兼容性和可扩展性。

A middleware for industry

This paper describes an innovative distributed framework for monitoring and control of large-scale systems by integrating heterogeneous smart objects, the world of physical devices, sensors and actuators, legacy devices and sub-systems, cooperating to support holistic management [1]. Its featured Service Oriented Architecture (SOA) exposes objects’ capabilities by means of web services, thus supporting syntactic and semantic interoperability among different technologies, including SCADA systems [23]. Wireless Sensor and Actuator Network (WSAN) devices and legacy subsystems cooperate while orchestrated by a manager in charge of enforcing a distributed logic. Particularly crafted for industrial networks are new middleware services such as dynamic spectrum management, distributed control logic, object virtualization, WSANs gateways, a SCADA gateway service, and data fusion transport capability. In addition, new application oriented objects such as shop floor, manufacturing line, welding station, robots, and cells have been introduced in the middleware. The combination of such objects and previous modules offers a new and flexible industry oriented middleware. A second contribution is in the form of traffic analysis conducted at the floor level. It shows the dominance of some end systems such as PLCs, the presence well behaved almost constant traffic made up of small packets.     

Enhancing Residential Gateways: A Semantic OSGi Platform

The OSGi (open service gateway initiative) service platform specification is the most widely adopted technology for building a control system for the networked home. Three main features contribute to its success. First, it supports various well-known protocols, simplifying communication among home devices. In addition, it defines a cooperative model for applications to dynamically discover and use services provided by others. Finally, it allows flexible remote management of these applications and the services they provide. So, an OSGi solution supports decentralization, diversification, and ubiquity not only in smart homes but in pervasive environments generally.     

Integration of service robots in the smart home by means of UPnP: A surveillance robot case study

Despite the large number of electronic devices that coexist in homes, only a few of them can be easily integrated in the same network. Given that smart home applications are based on the integration of many heterogeneous devices in the same network, the lack of interoperability can become a major issue in the development of advanced services. In this paper we tackle this issue developing an adapter to integrate the service robot Rovio into a smart home by means of Universal Plug and Play (UPnP). Different advanced services are designed to explore the possibilities derived from the integration of service robots in the smart home.     

Communication mechanisms in ecological network-based grid middleware for service emergence

Next generation grid systems are heading for globally collaborative, service-oriented and live information systems that exhibit a strong sense of automation. A collection of autonomous agents is searched, assembled, and coordinated in a grid middleware system to produce desirable grid services. An effective communication mechanism is vital to the effectiveness of the step to build a novel grid middleware system. In this study, we provide our grid middleware with a flexible communication solution to implement the complicated behaviors among different agents. We propose a transport mechanism of grid middleware, named as ecological network communication language (ENCL) and ecological network interaction protocol (ENIP) respectively from a low-level to a high-level implementation strategy of a communication mechanism. A series of experiments demonstrate that a service with some of the desired properties can emerge from interacting agents via the proposed solution.

SINGLETON: A lightweight and secure end-to-end encryption protocol for the sensor networks in the Internet of Things based on cryptographic ratchets

For many systems, safe connectivity is an important requirement, even if the transmitting machines are resource-constrained. The advent of the Internet of Things (IoT) has also increased the demand for low-power devices capable of connecting with each other or sending data to a central processing site. The IoT allows many applications in a smart environment, such as outdoor activity control, smart energy, infrastructure management, environmental sensing, or cyber-security issues. Security in such situations remains an open challenge because of the resource-constrained design of sensors and objects, or the multi-purpose adversaries may target the process during the life cycle of a smart sensor. This paper discusses widely used protocols that provide safe communications for various applications in IoT and also different attacks are defined. In this paper, to protect the IoT objects and sensors, we propose a comprehensive and lightweight security protocol based on Cryptographic Ratchets. That is, an encrypted messaging protocol using the Double Ratchet Algorithm is defined which we call Singleton, and the implementation of protocol is tested and compared to the implementation of the IoT standard protocols and a post-quantum version of the protocol. Various cryptographic primitives are also evaluated, and their suitability for use in the protocol is tested. The results show that the protocol as the building stone not only enables efficient resource-wise protocols and architectures but also provides advanced and scalable IoT sensors. Our design and analysis demonstrate that Singleton security architecture can be easily integrated into existing network protocols such as IEEE 802.15.4 or OMA LWM2M, which offers several benefits that existing approaches cannot offer both performance and important security services. For chat applications such as WhatsApp, Skype, Facebook Private Messenger, Google Allo, and Signal, a cryptographic ratchet-based protocol provides end-to-end encryption, forward secrecy, backward secrecy, authentication, and deniability.

     

Intelligent service processing in common USN middleware

The Ubiquitous sensor network (USN) is composed of several heterogeneous sensors with a variety of characteristics. An application based on the sensor network also has various requirements to provide services to users. Therefore it is important to develop the common USN middleware for flexible integration between the sensor networks and applications. Especially, this paper focuses on intelligent service management which is one of the main functions of USN middleware. Several applications in the sensor network environment support not only monitoring services, but also sensor-based context-awareness and intelligent services. In many applications, however, approaches to support intelligent services depend on the application because the standard method has been undefined yet. Therefore this paper proposes a common method for processing intelligent services in USN middleware independent of an application. The proposed method is implemented and evaluated as a component of USN middleware.

Middleware services for P2P computing in wireless grid networks

Advances in network architecture are changing application and service delivery. The wireless industry, for example, now talks of service grids - collections of separate wireless services collated from across the network. However, with current limitations in mobile device capabilities, a scalable and efficient middleware platform is essential. The authors' new middleware architecture, called scalable inter-grid network adaptation layers (signal), integrates mobile devices with existing grid platforms to conduct peer-to-peer operations through proxy-based systems. Combining mobile P2P applications with grid technologies could ultimately give mobile devices the power of supercomputers.

A proxy architecture for collaborative media streaming

Streaming media from the Internet is a successful application for end-users. With the upcoming success of mobile devices and home networking environments, cooperation among users will become more important in the future. To achieve such cooperation, explicit middleware standards have been defined. On the other hand, Internet conferencing applications do not handle collaborative streaming sessions with individual control for each user. We propose a new concept for cooperation exemplary for collaborative media streaming using IETF multimedia session control protocols together with a proxy architecture. This concept enables both synchronization among clients and flexible control to individual users.

FamiWare: a family of event-based middleware for ambient intelligence

Most of the middlewares currently available focus on one type of device (e.g., TinyOS sensors) and/or are designed with one requirement in mind (e.g., data management). This is an important limitation since most of the AmI applications work with several devices (such as sensors, smartphones or PDAs) and use a high diversity of low-level services. Ideally, the middleware should provide a single interface for accessing all those services able to work in heterogeneous devices. To address this issue, we propose a family of configurable middleware (FamiWare) with a really flexible architecture, instead of building a single version of a middleware with a rigid structure. In this work, we present the architecture of our middleware that can be configured, following a Software Product Line approach, in order to be instantiated in a particular device fulfilling specific application requirements. Furthermore, we evaluate that the decisions taken at architecture and implementation are the adequate ones for this kind of constrained devices.     

Secure communication mechanism for ubiquitous Smart grid infrastructure

Smart grid and advanced metering infrastructure (AMI) technologies have recently been the focus of rapid advancement and significant investment by many utilities and other service providers. For proper Smart grid deployment, smart energy home area network (HAN) must deploy smart meter along with other utility HAN devices and customer HAN devices. Energy service interface (ESI) is deployed as a HAN gateway which can provide two-way communications between HAN devices and utilities or service providers. However, in order to meet the envisioned functional, reliability, and scalability requirements of the Smart grid, cyber security must no longer be neglected. Thus, the development of a comprehensive security mechanism for AMI network is predominantly essential. A remote access to HAN devices may be required for either the customer that using his ubiquitous mobile device at the remote site or maintenance personals (either from utilities or service providers) those using handheld devices, which must be done securely. In this paper, we propose a security mechanism for remote access to HAN networks which is comprised of a lightweight and effective ECC-based entity authentication mechanism and ECC-based digital signature scheme. ECC-based entity authentication mechanism allows ESI as a gatekeeper to monitor the authentication process between two communicating entities. With a modified ECC-based digital signature scheme, secure data transfer between mobile devices and HAN devices has occurred. We have conducted security analysis, efficiency analysis as well as formal verification of the proposed mechanism.     

An optimal cluster based security and resilience of smart home environments using hybrid soft computing techniques

Smart home is the main part of smart intelligent system here the remote users share the sensitive information through an insecure medium to access such smart devices, which becomes security issues. The recent user authentication protocols have used to solve those problems and provide secure communication. Consumer traffic increase the risk of illegal user as legal user and radio channels are extra vulnerable to listeners. For further security enhancement, we proposed an optimal cluster based remote user authentication (OCRUA) protocol for smart home environment using hybrid soft computing techniques. The first contribution of proposed protocol is to introduce squirrel induced butterfly optimization (SBO) algorithm for cluster formation, which groups the smart devices. Then, we compute the cluster head (CH) using the teacher learning based deep neural network (TL-DNN) based on multiple design constraints. The second contribution is to illustrate remote user authentication using optimal elliptic curve cryptography (OECC) which encrypts the sensitive information before forward to gateway. At long last, the concert of planned OCRUA protocol evaluates use different replication scenarios and shows the effectiveness over the existing state-of-art protocols.
