Spectrum Handoff Decisions

In modern society wireless communication plays a very important role with huge increase of users, services and standards. Although there are several pros of using cognitive radio networks, for example increasing the spectrum utilization of wireless networks, but still there exist some challenges which need to be discussed in detail First, since cognitive radio networks are planned to operate over a heterogeneous spectrum environment, which comprises of both licensed and unlicensed spectrum bands, most of the research has been done in only the licensed band of the spectrum and only some research has been carried out in such an environment as merging licensed and unlicensed spectrum bands for transmission increases the spectrum utilization of cognitive radio wireless networks. There is need to develop new spectrum handoff schemes to improve the performance of the secondary users in terms of their handoff delay.

Image Filtering Based on GMSK

Image Denoising is an important pre-processing task which is used before further processing of image. The purpose of denoising is to remove the noise while retaining the edges and other detailed features. This noise gets introduced during the process of acquisition, transmission and reception and storage and retrieval of the data. Due to this there is degradation in visual quality of image. The noises which are of major considerations are Additive White Gaussian Noise AWGN and Impulsive Noise.

Design and Simulation of Low Noise Amplifier at 15 GHz Using Advanced Design System ADS

the first stage of each microwave receiver there is low noise amplifier LNA circuit, and this state has important rule in quality factor of the receiver. In this study, design and simulation of 15 GHz low noise amplifier LNA have been explored. This simulation has been performed by using the Agilent Advanced Design System ADS software. It also describes the design and simulation of a high frequency low noise amplifier, with high gain and low noise using MESFET for frequency 15GHz.

A single stage LNA has successfully designed with 14.5 dB forward gain and 0.003dB noise figure in frequency of 15GHz.The NE76000 transistor was chosen for the design of the LNA due to its low noise figure, stability, and good gain at high frequency, good input and output impedance matching. Also the designed LNA should be working stably in frequency of 15GHz.

Supporting Spatial-Temporal Provenance Location Proofs for Ad-Hoc Mobile Users

Spatial-Temporal Provence STP are quickly becoming immensely popular. In apply the position that users of the communicate to the location-based services LBS . Malicious users may lie about their spatial-temporal provenance STP without a carefully designed security system for users to prove their past locations. 

This type of attack will have a severe impact on applications of the period of time traffic office, location based on the access management, the traffic of the process to be in electronic election. In this paper, we present the Spatial-Temporal provenance Assurance with Mutual Proofs STAMP scheme. STAMP is designed for ad-hoc mobile users generating location proofs for each other in a distributed setting. However, LP versions can easily accommodate trusted mobile users and wireless access points. 

STAMP ensures the integrity and non-transferability of the location proofs and protects users privacy. A semi-trusted Certification Authority is used to distribute cryptographic keys as well as guard users against collusion by a light-weight entropy-based trust evaluation approach. Our prototype implementation on the Android platform shows that STAMP is low-cost in terms of computational and storage resources. Extensive simulation experiments show that our entropy-based trust model is able to achieve high collusion detection accuracy.

Literature Review on Single Image Super Resolution

In this paper, a detailed survey study on single image super-resolution (SR) has been presented, which aims at recovering a high-resolution (HR) image from a given low-resolution (LR) one. It is always the research emphasis because of the requirement of higher definition video displaying, such as the new generation of Ultra High Definition (UHD) TVs.

Super-resolution (SR) is a popular topic of image processing that focuses on the enhancement of image resolution. In general, SR takes one or several low-resolution (LR) images as input and maps them as output images with high resolution (HR), which has been widely applied in remote sensing, medical imaging, biometric identification.

Image Denoising by OWT for Gaussian Noise Corrupted Images

In this paper denoising techniques for AWGN corrupted image has been mainly focused. Visual information transfer in the form of digital images becomes a vast method of communication in the modern scenario, but the image obtained after transmission is many a times corrupted with noise.  OWT SURE-LET color denoising is based on linear expansion of thresholds (LET) and optimized using Stein' unbiased risk estimate (SURE).

In this method, noisy color image is processed through Orthonormal Wavelet Transform (OWT) followed by thresholding of each channel wavelet coefficients. Finally, inverse wavelet transform is applied to bring back the result to the image domain. It efficiently exploits inter channel correlations. In order to remove the noise in multichannel images, OWT is applied on each channel.

Efficient Cluster Head Replacement LEACH Protocol for Wireless Sensor Networks

In this work, M-LEACH (Modified Distributed Energy Efficient Clustering) protocol, a new variant of LEACH is proposed after survey of LEACH. The proposed M-LEACH is designed for three different segregations for the nodes to elongate the stability & lifetime of the network. Hence, it increases the heterogeneity & energy level of the network.

In LEACH, amplification energy is set same for all kinds of transmissions. Using low energy level for intra cluster transmissions with respect to cluster head to BS transmission leads in saving much amount of energy. Moreover, multi power levels also reduce the packet drop ratio, collisions and or interference for other signals. The proposed M-LEACH outperforms to existing classical LEACH.
