Enhanced Artificial Bees Colony Algorithm for Travelling Salesman Problem
This paper presents an improved algorithm for Travelling Salesman Problem using Artificial Bee Colony Algorithm. This algorithm is used to find shortest path such that a salesman visit each city exactly once. The ABC algorithm used is inspired by the collective behavior of bees to find better food sources around the hive.
Comparative Analysis of Network Simulator for Vehicular AdHoc Networks (VANET) Communication
Recently, Vehicular ad hoc network (VANET) can offer various services and benefits to VANET users and thus deserves deployment effort. Intelligent Transportation Systems (ITS) are aimed at addressing critical issues like passenger safety and traffic congestion when integrates ICT with transportation infrastructure. This infrastructure is called Vehicular Ad hoc Networks (VANET), Vehicular communication systems facilitate communication devices for exchange of information among vehicles and between vehicles and roadside equipment. Working in tandem with the fielded Intelligent Transportation Systems (ITS) infrastructure, VANET will enhance the awareness of traffic by aggregating, propagating and disseminating up-to -the minute information about existing or impending traffic-related events. In support of their mission, Here we consider that every study should chose the appropriate simulator based on its requirements
Comparative Study of Spatial Watermarking of Various Video formats
At the forefront of the information world it is all available in the shape of digital media. Digital watermarking has been introduced to provide authentication owners and copy right protection. Digital video watermarking is the process of embedding a digital code in the digital video sequences. Digital video watermarking is nothing but a sequence of consecutive still images. Over recent years applications based on video, pay-per-view, video-on-demand, video broadcasting are becoming more and more popular, which yield requirements to increase safety in the delivery of video. In this paper, the concept of digital video watermarking, its terminology, principle, properties, applications, and classification is introduced i.e. the detailed technique of watermarking such as Spatial Domain Watermarks (Correlation-Based Techniques, Least Significant Bit Modification), Frequency Domain Watermarks (Discrete Cosine Transform, Discrete Wavelet Transform). We have taken three video codec i.e. MPEG, IV 50, MJPG of respective video formats MPEG2, H.261 and AVI, which has been watermarked using BITGET video watermarking technique and comparative study among different video formats has been done to provide chaotic map and the efficient video format for watermarking which withstand on the essential ingredients such as fidelity, robustness, use of keys, blind detection, capacity and speed, statistical imperceptibility, low error probability, real-time detector complexity
Codes from the Cyclic Group of Order Three
In this paper we use cyclic group Z3 and its regular representation to produce a couple of linear error-correcting codes. We also discuss their duals.
An Hybrid approach for Intrusion Detection
Now a day’s security in network has become very important issue in network. Hackers and intruders are trying to crack the systems of various organizations. Intrusion detection has traditionally been performed at the operating system level by comparing expected and observed system resource usage. Gradually with time network intrusion detection came into existence .And thereafter an age of Data Mining came, which lead to evolution of many ideas in intrusion detection. Many algorithms like A-Priory algorithm were used in network to avoid hackers into the network. A new approach has been proposed in which anomaly detection takes place with the help of two approaches called FP-Growth and Registry Anomaly Detection which made the Intrusion Detection System much more efficient and Accurate as compared to the existing System.
A Comparison between Scilab inbuilt module and Novel method for image fusion
Image fusion is one of the important embranchments of data fusion. Its purpose is to synthesis multi-image information in one scene to one image which is more suitable to human vision and computer vision or more adapt to further image processing such as target identification. This paper mainly compares the Scilab inbuilt module and novel method for image fusion. By using scilab as experimental platform, we approved the feasibility and validity of method. The result indicate that the fused image quality would be very effective and clear.
