In this paper, the author presented how Man-in-the-Middle problem can be executed by an attacker. He also proposed a simple and lightweight protocol that will make it undesirable for black hats to carry out this act. The proposed detection protocol has been simulated in a wireless environment to test the effectiveness of the detection mechanism. In all cases the simulated man-in-the-middle attack was detected. The performance of the proposed detection mechanism was evaluated against an existing detection mechanism.
The objective of this paper is the performance of WiMAX under Stanford University Interim (SUI) fading channels in IEEE802.16 using different data rates and digital modulation (BPSK, QPSK, 16-QAM and 64-QAM) techniques were analyzed. Most existing systems, based on performance and evaluation under channel condition are limited to AWGN, ITU in WiMAX. The performance of OFDM physical layer in WiMAX based on the simulation results of Bit Error Rate (BER) versus the ratio of bit energy to noise power spectral density (Eb/No) and the Packet Error Rate (PER) versus the ratio of bit energy to noise power spectral density (Eb/No). The system parameters used in this paper are based on IEEE 802.16 standards. The performance analysis of WiMAX is done in ADS simulation.
Substation Automation Networks are increasingly deployed with devices adhering to IEC 61850 communication standards. Substation equipment can be categorized as critical infrastructure and hence the expectation on the availability and reliability is high. The high levels of availability in substations are required for the electronic devices and communication devices as well. Due to the nature of the application, the communication latency of the substation events shall be very high due to the criticality of the information carried in the network. One of the methods to improve the availability of the communication system is to provide redundancy. The IEC 61850 communication is based on the Ethernet and hence carries some disadvantages like very fast switchover and recovery in the event of link or switch failures. The paper aims at study of the redundant communication paths, recovery scenarios, tolerance levels, fault detection and associated impact on the communications. The above study is performed in the context of an automation system for integrating the Distributed Energy Sources to the Electrical Power System.
The ridge waveguides is the most commonly used structure in integrated optics, especially in semiconductor diode lasers. Demands for new applications such as high-speed data backplanes in integrated electronics, waveguide filters, optical multiplexers and optical switches are driving technology toward better materials and processing techniques for planar waveguide structures. This paper addresses mainly the application of modal method to analyze the 3-D ridge waveguide structure. We have analyzed the modal index of ridge waveguide using various numerical methods based on Beam propagation method. Scalar, semi-vector, and full-vector propagation analysis are done for different etched film thickness (d) . The results calculated by the proposed scheme for dispersion characteristics of ridge waveguides shows good agreement with previously published data based on other rigorous numerical methods.
In content-based image retrieval (CBIR), color and texture are the most intuitive image features and it is widely used. But the current color feature can describe the semantics of the whole image effectively, but does not reflect characteristics of the color salience objects in an image. For the purpose of giving paper proposes a new color feature description model is proposed at first. This model integrates the intensity, the color contrast and self-saliency, sparsity and centricity saliency to describe human color visual perception of the image. Then, the new color feature descriptor is calculated by weighting the significant bit-plane histograms with color perception map. Finally, similarity measure is presented for the new color feature. Then for more efficient retrieval again the retrieved images are then compared for texture .Now because of the texture of salience retrieved image more accurate images can be retrieved. Experiment results show that the proposed color and texture feature is more accurate and efficient in retrieving images with user-interested color objects. Here a typical query can be a region of interest provided by the user, such as outlining patch in satellite image. Compared with the other retrieval methods, the proposed technique improves the retrieval accuracy effectively.
