IoT covers a larger range of connections and involves more semantics. Traditional Internet and telecom networks focus on information transfer, but IoT focuses on information services. By combining sensor networks, Internet, telecom networks, and cloud computing platform, IoT can sense, recognize, affect, and control the physical world. The physical world can be unified with the virtual world and human perception. This lecture discusses IoT technology from three aspects: ubiquitous information sensing, ubiquitous network convergence, and intelligent information service. In this part, we discuss the architecture of sensor network and the status of the industry.  相似文献

The Internet has made an important part of the national information infrastructure of China. Without the Internet, social informationization cannot be popularized to an extent as today. Upon the coming of a new year, we especially invited Mr. Jiang Lintao, a famous communication expert and the chief engineer of China Academy of Telecommunication Research of the Ministry of Information Industry, to give us his opinions on the opportunities and challenges brought by the Internet. According to Mr. Jiang, the appearance of the Internet has brought great impact on telecommunications networks. It has broken the monopoly of the telecom industry in telecom services and promoted the development of technologies. Characterized by continuous innovation and aggressiveness, Internet services guarantee their dominating position in broadband networks, and put the telecom industry in a quite passive position. The telecom industry is still looking for new development direction and breakthroughs in technology so as to regain its leading position. Mr. Jiang also pointed out that the future of both telecom networks and the Internet should be next generation network, which will be the main body of the future national information infrastructure. The essential features of the next generation network should be as follows: it should be secure and trustworthy enough to safeguard users’ rights, national security and social stability; it should be scalable enough to allow sustainable development; it should be compatible with current main technologies, co-exist with them and allow their graceful evolution; and it should provide a network platform for everybody to innovate.  相似文献

The existing Internet technologies and the original Internet design concept cannot meet the requirement of development, due to the fast development of the Internet, great changes of the Internet user groups and the tremendous transformation of the Internet external environment. The Internet is at a development crossroad; and its direction of development has attracted great attention from the world. On the other hand, the telecom industry is in a rather passive position as the result of the great impact the Internet technology has posted on it. The telecom industry has failed in defining its own developing direction and technology breakthrough; therefore, it is also at a crossroad. The development of both the Internet and the telecom networks will lead to the development of Next Generation Network (NGN) technologies. Industrial attention and research should be focused on the key NGN technologies, solutions to problems in the development of these technologies, and their commercialization in a short term.  相似文献

Cloud computing is the latest major evolution in computing technology.The convergence between cloud computing and telecom networks could significantly reduce costs and bring new business opportunities for operators.Currently,traditional telecom operators are embarrassed by the fact that the increase in revenue cannot catch up with the quick growth of users and the expansion of networks.With the introduction of the cloud computing technology,operators can virtualize the network functions through low-cost COTS IT hardware.All kinds of existing services can be cloudified and thus obtain the benefits of statistical multiplexing among IT resources.With the Telco Cloud architecture,operators can manage both IT infrastructures and network resources intelligently in order to adapt to the dynamic demands from the application and to establish open platforms for developing new services.  相似文献

owadays, traditional voice services can no longer meet the increasing demands of people's life and work. Fashionable young people pursue personality and novelty, while businessmen seek non-stop and convenience. So Value-Added Service (VAS) is becoming the main income source for most telecom operators. A growing number of telecom operators are turning to VAS for enhancing the competitive edge of traditional networks in response to market changes. Therefore, VAS such as Short Message Servi…  相似文献

The convergence of telecom networks requires an improved Quality of Service (QoS) solution. The introduction of the QoS resource control architecture based on the IP Multimedia Subsystem (IMS) framework is a way to solve QoS problems in the converged networks. Services,QoS guarantee,resource control and accounting functions are integrated into this IMS-based QoS control architecture. It is a solution to the problems currently facing the fixed network operators,helping them offer more QoS-guaranteed multimedia services such as 3D games,and make a transition from bandwidth providers to genuine telecom services providers.  相似文献

Publish/subscribe paradigm is often adopted to create the communication infrastructure of the Internet of Things(IoT)for many clients to access enormous real-time sensor data.However,most current publish/subscribe middlewares are based on traditional ossified IP networks,which are difficult to enable Quality of Service(QoS).How to design the next generation publish/subscribe middleware has become an urgent problem.The emerging Software Defined Networking(SDN)provides new opportunities to improve the QoS of publish/subscribe facilities for delivering events in IoT owing to its customized programmability and centralized control.We can encode event topics,priorities and security policies into flow entries of SDN-enabled switches to satisfy personalized QoS needs.In this paper,we propose a cross-layer QoS enabled SDN-like publish/subscribe communication infrastructure,aiming at building an IoT platform to seamlessly connect IoT services with SDN networks and improving the QoS of delivering events.We first present an SDN-like topic-oriented publish/subscribe middleware architecture with a cross-layer QoS control framework.Then we discuss prototype implementation,including topic management,topology maintenance,event routing and policy management.In the end,we use differentiated services and cross-layer access control as cross-layer QoS scenarios to verify the prototype.Experimental results show that our middleware is effective.  相似文献

The rapid development of Peer-to-Peer (P2P) technologies and applications has a great impact on telecom services and operations. Operators should refine the pipeline operation and develop characteristic P2P services. They must comply with the rule of Internet services, and design manageable and operational P2P solutions combining the advantages in network, resource and subscriber, providing users with better P2P service experience. ZTE’s manageable and operational P2P solution provides operators with customized authorization and accounting functions. Its development is based on the broadband service management platform widely used in the live networks. ZTE’s P2P system is stable and reliable.  相似文献

To guarantee the security of Internet of Things(IoT)devices,the blockchain tech?nology is often applied to clustered IoT networks.However,cluster heads(CHs)need to un?dertake additional control tasks.For battery-powered IoT devices,the conventional CH se?lection algorithm is limited.Based on the above problem,an unmanned aerial vehicle(UAV)network assisted clustered IoT system is proposed,and a corresponding UAV CH se?lection algorithm is designed.In this scheme,UAVs are selected as CHs to serve IoT clus?ters.The proposed CH selection algorithm considers the maximal transmit power,residual energy and distance information of UAVs,which can greatly extend the working life of IoT clusters.Through Monte Carlo simulation,the key performance indexes of the system,in?cluding energy consumption,average secrecy rate and the maximal number of data packets received by the base station(BS),are evaluated.The simulation results show that the pro?posed algorithm has great advantages compared with the existing CH selection algorithms.  相似文献

Traditional signaling based telecom service control architecture, intelligent network service control architecture, and even Next Generation Network (NGN) and IP Multimedia Subsystem (IMS) that are pictured as the fundamental of future services have become an obstacle for telecom service development because they are closed in service creation and service control and implemented on a centralized computing platform. As newest technologies in Internet, distributed computing and enterprise information services, Service-Oriented Architecture (SOA), Web services and Web 2.0 have been widely recognized in information and service industry in past years. According to the SOA definition of OASIS, SOA will bring tremendous changes in capability, service and service interface, compared with traditional telecom service architecture. Moreover, it adds a capability-service transform mechanism and greatly simplifies application development.  相似文献

As the development of Internet of things (IOT), massive sensors have been deployed as the public infrastructure. With the development of in-depth applica- tions in IOT, service discovery and composition are chal- lenges to the end users. To handle this challenge, we de- velop a service mining scheme based on semantic for IOT to provide users with interesting composite services. In this scheme~ services can be combined and recommended to users actively according to the calculation of service sim- ilarity and an updatable semantic database. By the results of service similarity, useless compositions can be filtered out so that energy consumption on service flooding will be reduced. The update strategy of semantic database is also given out, by which the composite services can keep up with time and be more applicative. The benefits of the proposed method are that all operations such as can culating, filtering, and updating are simple enough to be performed in sensor networks.  相似文献

Overlay networking: applications and research challenges   总被引:3,自引:0,他引:3  
Overlay networking is one of the perspective solutions to today‘s Internet challenges. At basic service level, overlay networks can serve as a supplement and enhancement of existing services, such as routing and addressing. At high application level, overlay networks can be used for applications, which are difficult to deploy in existing IP architecture with some specific reasons, e.g., they need high-level information, which is hard to obtain by underlying layers. To address the heterogeneity of today‘s Internet, overlay networks provide ways to service availability and desirable performance while retaining scalability. In contrast to changing the existing network layer, overlay networks allow bootstrapping, which is most important in the development of Internet infrastructure. Various applications of overlay networking are clarified in this paper. Research challenges including routing and searching in overlay networking are also identified.  相似文献

Wideband Wireless Mobile Internet (WWMI) has become one of the most important technologies for Modern Service. The Modern Service information communication multi-access network can easily realize the new operation modes formed by various Modern Service support systems. We think that under the new operation modes, the charges on calling and information will become more negligible, while the charge on services provided by the direct service support of various Modern Service platforms will turn into a major revenue source. It is suggested that the operators build an operation service support platform with common services to cooperate with thousands of information websites, help clients to transform information into profit and carry out operations and services.  相似文献

Link flooding attack(LFA) is a fresh distributed denial of service attack(DDoS). Attackers can cut off the critical links, making the services in the target area unavailable. LFA manipulates legal lowspeed flow to flood critical links, so traditional technologies are difficult to resist such attack. Meanwhile,LFA is also one of the most important threats to Internet of things(IoT) devices. The introduction of software defined network(SDN) effectively solves the security problem of the IoT.

The original infrastructure of the Internet can no longer meet personalized and diversified demands of current increasing network subscribers. It has exposed many defects and shortcomings. For examples, the mechanism of using ports to distinguish services is inflexible and dangerous with the emergence of various services; the current Internet architecture does not make use of the close relationship between network resources and services, but simultaneously maintains two processing systems for the resources and services respectively, wasting both subscribers’ time and network resources; the Internet class of services granularity is not fine enough, failing to meet personalized and diversified user demands. In order to solve these problems, this paper discusses the mechanisms and key technologies for pervasive services in the new-generation Internet. The paper focuses on the definition, classification and identifier design of personalized and diversified user services. The service identifier design fulfills the unified identifier and processing of various network services, discovers the close relationship between services and resources, and can offer personalized and diversified services according to users’ demands.  相似文献
