Online shopping has been emerging in the past years and significantly affected conventional shopping styles, but many people still favor retail stores for reasons such as social lives and trying dresses. When they find interested goods, usually hope to obtain more information of them from online shopping for price comparison and so forth. However, state of the art solutions either have users frequently...
In this paper, the convergence of Internet of Things (IoT) and 3GPP LTE-A network is discussed. With the cooperation of enormous smart devices, various kinds of information would be gathered and transmitted to the central control and processing entity, 3GPP LTE-A network provides the ideal access network for the IoT. Meanwhile, there exist several potential issues for the convergence of IoT and 3GPP...
For the shortcoming that K-Nearest Neighbor(KNN) classification method is not efficient and it is difficult to determined the optimal parameter value K, a new KNN classification method based on spanning tree document clustering is presented. The basic idea is that using the clustering algorithm based on spanning tree to realize automatic clustering, each sub-tree generated retain a few core document...
Cyber Physical Systems (CPS) are the intelligent systems which physical and engineered systems are closely integrated. This paper first introduced the concept of CPS, summarized the status of CPS and analyzed the differences between CPS and popular “The Internet of Things”. Followed list the CPS applications of smart grid, water distributed networks and assistive devices, described the efforts that...
Peer-to-peer (P2P) applications have shown their popularity in the Internet, while become a burden of Internet Service Providers (ISPs) because they produce huge traffic on network. The enormous traffic comes from the fact that when P2P systems construct overlay networks, they ignore the underlying network topology, so most of the connections are between remote peers and cross different networks....
This paper mainly presents that design principle and main technology of unified managed government website-group which is based on ASP.NET technology. This system adopts the system architecture based on distributed, multi-site and multi-column, and applied the design idea of website-group to the construction of government portal website, which can effectively integrate sub-website of each department,...
This paper presents a mechanism to manage a dynamic group in an automatic way for sending Group IM (instant message) based on presence service in IMS system. Presence technology is gaining significant interest nowadays. It can show the user's presence information in real time. Presence based services are driving new business opportunities and changing every aspect of our daily life, especially in...
NAT (network address translation) are widely used to isolate the private networks from internet. Unfortunately, NATs block the data transmitted directly between two nodes under different private networks in many peer-to-peer applications. A protocol, STUN (simple traversal of UDP over NATs), has been proposed by IETF to solve the problem, but it costs great network bandwidth and transmission delays...
The critical issue that confronts peer-to-peer networks is the efficient location of the node that stores a desired data item. Chord is a successful resource location protocol based on distributed hash table. However, if the desired data item is stored on a node that is count-clockwise close to the query node on the chord ring, the lookup latency might be high because of its clockwise lookup strategy...
A new algorithm for Web GIS fault location in distribution network is presented by using the trouble calling information in this paper. Through deeply study of rough set theory, the algorithm is considered the topology characteristics of the distribution network which have the large-scale and multi-line equipment. Based on the methods of identification matrix attribute reduction and improved value...
The intelligent emergency response system was developed to compute and simulate the spread of hazardous materials leak with WebGIS when emergency happens, such as hazardous material leak accidents. In the system, much of data correlative to the rescuing strategy, such as geography location details, the spread concentration changes with time, the population distribution around, the rescue force around,...
This paper proposes the complete QoS (quality of service) architecture for integration of space network with infrastructure networks. The technology, service differentiation mechanisms, network control mechanisms and user-to-networks mechanisms are discussed. The modules required in the network elements and its integration to provide end-to-end QoS in Space networks are presented. The proposed solution...
Mobile environment has been one of focuses of computing, communication and management. Mobile review ranking problem, for the first time, is brought out in this paper. Also, a novel ranking algorithm, TiCom, is proposed for mobile review ranking. TiCom is based on the idea of time compensation, and is used to prevent fresh voting item from being ranked too high or too low. Experimental results show...
The Internet-based tele-operation is becoming an important research field in the past years. Most exist works are based on the wired Internet and the PC computers, which largely limited the robot's movement and the tele-operation system's portability. This paper presents a design and implementation of an Internet soccer tele-operation system based on Pocket PC via the 802.11b wireless network. According...
The Internet-based teleoperation has become a popular research topic during the recent years. More and more fields are being involved and one of them is the multi-robot systems. Multi-robot systems have the ability to perform better in a complex environment; however, it is difficult for the robots to complete tasks autonomously, thus a human operator is needed to contribute his ability to direct the...
The Internet-based teleoperation has been studied in more and more potential fields in the past years. The interest in multi-robot systems arises during recent years for their ability to perform better in complex environment. However, it is difficult for robots to perform tasks autonomously in complex conditions, thus a human operator at the remote site is needed to contribute his intelligence to...
The architecture of an Internet-based teleoperation system with force feedback control has been presented. The notion of supermedia in the teleoperation was introduced firstly. And then the artificial potential field method was used to produce virtual force which was displayed by force feedback device. A kind of general task distribution algorithm had been proposed, in which tasks were distributed...
