This paper proposes a method to detect the Internet Key Exchange (IKE) phase 1 messages in IPSec VPN, which is called Context-based Deep Packet Inspection (CDPI). In conventional IPSec VPN detection methods, the packet filter firewall only detects the heads of the IP packets and other protocols. Therefore, if the attackers impersonate messages of the same heads as the actual IPSec messages, the conventional...
To resolve real-time the traditional water quality detection method, a novel system of remote water quality measuring and monitoring based on wireless sensor network (WSN) and Code Division Multiple Access (CDMA) technology is proposed. The WSNs can monitor the targets and water quality information of the waters through the cooperation of a large amount of sensors. The optimization of node distribution...
This paper proposes two protection algorithms, Segment-Based Protection (SBP) and Path-Based Protection (PBP), in fault-tolerant multi-domain optical networks to support waveband grouping with the layered auxiliary graph concept. To the best of our knowledge, this paper is the first study to achieve the fault-tolerance and waveband switching in multi-domain optical networks. Simulation results show...
In recent years, remote sensing technology has been widespread applied in coastal resources survey and ecological environment research. The methods of coastal object extraction have been steadily innovating. Compared with traditional manual interpretation and classification based on pixel, the object-oriented technique can increase classification accuracy and reduce the salt-pepper noise considerably...
Based on practical construction management of large construction projects, this paper demonstrates how to establish a network information system suitable for project construction to facilitate prompt information communication, real-time process control and decision support so as to achieve overall control of construction progress, cost and quality and to realize the scientific and modernized project...
Routing is simultaneously the most complicated function of a network and the most important problem for network. In this paper, based on current crank-back mechanism, a new mechanism of crank-back based on re-routing in crank-back node is proposed. Optical networks are high-capacity telecommunications networks based on optical technologies and component that provide routing, grooming, and restoration...
The popularity of the Internet and its related services continues to be one of the main reasons for the explosive growth of traffic volume in global information and telecommunications networks. This trend of data-centric traffic growth, emerging new requirements and the need of network operators to reduce investments and operational costs (capital expenditure and operational expenditure) represent...
In the optimization of operational networks the most important target is the minimization of congestion. Congestion can be divided into two types, congestion in the case where resources are insufficient to carry all the traffic, and congestion in the case where resources are divided inefficiently so that a part of the network is over-utilized while another part of the network has unused band-width...
In a paper, Roscoe has proposed two algorithms that can preserve a form of consistency in the distributed databases arranged a ring, and validated them using a group like algebra, invented by the same author. In this paper, we have simplified one of the algorithms and tried to validate it by applying a simple set theory. We suppose that each process located at a node of the ring emits one only one...
In this paper, efficient algorithms of the arithmetic operations over Optimal Extension Field have been considered. An arbitrary field element is represented by the Lagrange Representation, and transformation forward and backward between the Lagrange Representation and the vector of polynomial coefficients of the field element has been speeded up by applying DFT (discrete Fourier transform) over a...
This paper investigates the passivity problem for uncertain neural networks with time-varying delays. By constructing proper Lyapunov functionals and using some analytic techniques, a new condition is given to ensure the passivity of the uncertain neural networks with time-varying delays. The passivity condition is expressed in terms of linear matrix inequality (LMI), which can be easily solved by...
Urban gridding management model creates a new era of urban management. Scientific and rational division of the grid can carry truly out a new concept of urban governance: fining, gridding, information, humanization. Service GIS is a Service-Oriented Architecture (SOA) of the Component GIS. It brings the third generation of geographic information-sharing revolution which is data sharing and function...
