To develop the production capability and decrease the cost of container terminal is the goal of port enterprises Business Processing Rebuilding (BPR). It is even the important project of studying to every port in the world. This paper shows the innovation approach, which integrated IT technology such as Computing, Communication and Controlling (CCCT), in the BPR of container terminal production. The...
In order to improve the tracking and positioning accuracy of theodolite self-stabilization tracking based on mobile platform, the position of object is transformed from platform coordinate system to earth coordinate system by using coordinate axis circumrotation. A method of forecast tracking technique based on mobile platform is presented. The former compound angle is transform from platform coordinate...
One of the major problems in Mobile Grid environments is the optimal distribution and replication of data files, in order to improve and maintain a high overall throughput of Grid jobs that access files. A data replica replacement algorithm based on value model is proposed and the arithmetic method to calculate replica value is introduced. This algorithm adapts to the high variation environment in...
With ARM7 as the core, the new intelligent mobile vehicle checking system integrated a lot of hardware modules such as video capture, GPS positioning and wireless transmission, the design of the system software used the embedded software developing platform based on ADS integrated development environment. By the hardware/software co-design, the new intelligent mobile vehicle checking system implemented...
To improve the quality of search algorithm in all IP broadband mobile networks, a hybrid Peer-to-Peer (P2P) search algorithm (HPSA) is proposed which is based on the features of P2P technology and all IP broadband mobile networks. Firstly, this algorithm defines parameters to decide the threshold by means of grey relational analysis (GRA); then we put forward an adaptive threshold method to adapt...
Under the premise of fully analyzing the security requirements and security threats of mobile payment, the analysis of secure mobile payment based on SET protocol in the WAP environment has been made, then, this paper points out its various flaws exist in the transaction process. Meanwhile, making improvements on the basis of the original Mobile Payment based on SET protocol, then proposed Mobile...
In the Internet, nodes are identified using IP addresses that depend on their topological location. IPv4/IPv6 translation technology involves address mapping between IPv6 and IPv4 nodes and the methods used to translate protocols, where nodes are in their respective IP version of network. The various IPv4 addressing mechanisms and addressing architectures are studied. The detailed study reveals that...
Existing mobile ad-hoc routing protocols are based on a discrete, bimodal model for links between nodes: a link either exists or is broken. This model cannot distinguish transmissions which fail due to interference or congestion from those which fail due to their target being out of transmission range. A statistical network link model is introduced to represent the quality of the link by a statistical...
This article raised the traffic detection and analysis program based on more and more data services in GPRS networks. By bringing in the traffic acquisition module, data analysis and processing module, database module and WEB terminal blocks, this article achieves the function of traffic collection, analysis and processing of the GPRS.
3S technology is an important part in the science and technology of Surveying engineering, 3S technology is the GPS, GIS, and RS technology, the development and current status of 3S technology integration and applications are discussed in detail in this paper.
This paper proposes a dynamic Probabilistic Priority Adaptive Time-Threshold-based bandwidth allocation Scheme for Multimedia services (PPATTSM) in cellular networks. Because future data service will occupy a large portion of all services in next generation mobile networks and forced termination of an ongoing call is clearly less desirable than blocking of a new call attempt, there is much significance...
Because of the environment and the nature of the signal itself, GPS or wireless mobile positioning technology always has any unavoidable defect. But higher coverage percentage, reliability or precision than single positioning can be gained if integrating at least two positioning technologies' advantages and avoiding their deficiencies. So the developmental trend of mobile positioning technology is...
In this paper, we propose an energy-balanced cross-layer multi-path routing algorithm for wireless Ad hoc networks. This algorithm utilizes cross-layer information of the network nodes and can balance the energy consumption of the network nodes in flow distribution under the situation that the network topology is maintained unchanged; moreover, the transmission power can be adjusted in routing process...
