Objective: The main intent of this research is to enhance the network capacity and compute the shortest path for reducing congestion in the wireless adhoc networks. Methods: In this manuscript, an innovative technique is introduced which is used to enhance the performance of a-MOC-CD based broadcasting and routing by using D equivalence classes of CDS. With that, we also apply minimum spanning tree for calculating the shortest path for avoiding the congestion to accomplish proficient broadcasting and routing in wireless networks. Results: The alpha-DEC-MOC-CDS (alpha-D-equivalence class- MOC-CDS) shows high network capacity when compared to the existing alpha-MOC-CDS. The proposed method improves the network capacity by using D equivalence classes and also the minimum spanning tree is used to recognize the shortest path. If the number of iterations is increased, the transmission capacity in alpha-DEC-MOC-CDS is 4.07, the medium, rout¬ing path length is 6.72 and the average routing path length is 5.73. The comparison result shows that the proposed method achieves better network capacity when compared to the existing system. Conclusion: The findings demonstrate that the alpha-D-equivalence class- MOC-CDS method is presented and suggested that this method high network capacity.Keywords

Wimax which represents world wide interoperability for microwave access is a major part of broad band wireless network having IEEE802.16 standard providing fixed and mobile platform for broadband internet access. The Wimax forum has adopted IEEE 802.16 OFDM PHY layer for the equipment manufacturer due to its robust performance in multipath environment. In this paper we investigate the simulation performance of IEEE 802.16 OFDM PHY layer. The Stanford University Interim (SUI) channel models are selected for the wireless channel in the simulation and we also investigate the estimation of channel at high frequencies with conventional Least Square (LS) and Minimum Mean Square (MMSE) estimation algorithms. Channel state information for OFDM systems based on pilot carrier is carried out through Matlab simulation. The performance of MIMO OFDM is evaluated on the basis of Bit Error Rate (BER) and Mean Square Error (MSE) level.

Graph coloring is one of the most important concepts in graph theory and is used in many real time applications. Various coloring methods are available and can be used on requirement basis. The proper coloring of a graph is the coloring of the vertices and edges with minimal number of colors such that no two vertices should have the same color. The minimum number of colors is called as the chromatic number and the graph is called properly colored graph. In this paper we reviewed the vertex coloring concepts, properties and theorem related to various graphs of vertex colorings and its chromatic number.Keywords

Gene selection is an important issue in microarray data processing. In this work, propose a capable method for selecting relevant genes. This work aim at finding the smallest set of genes that can ensure highly accurate classification of cancers from microarray data by using supervised machine learning algorithms. Initially utilized spectral biclustering to achieve the best two eigenvectors for class partition. Then gene combinations are chosen based on the similarity among the genes and the best eigenvectors. Proposed simple yet very effective method involves two steps. In the first step, choose some important genes using a feature importance ranking scheme. In the second step, test the classification capability of all simple combinations of those important genes by using a good classifier. This work demonstrates semi-unsupervised and T-Score gene selection method using two microarray cancer data sets, i.e., the lymphoma and leukemia data sets. Experimental result shows proposed method is able to identify a single gene which leads to predictions with very high accuracy.

Web browsers are provided with complex information space where the volume of information available to them is huge. There comes the Recommender system which effectively recommends web pages that are related to the current webpage, to provide the user with further customized reading material. To enhance the performance of the recommender systems, we include an elegant proposed web based recommendation system; Truth Discovery based Content and Collaborative RECommender (TDCCREC) which is capable of addressing scalability. Existing approaches such as Learning automata deals with usage and navigational patterns of users. On the other hand, Weighted Association Rule is applied for recommending web pages by assigning weights to each page in all the transactions. Both of them have their own disadvantages. The websites recommended by the search engines have no guarantee for information correctness and often delivers conflicting information. To solve them, content based filtering and collaborative filtering techniques are introduced for recommending web pages to the active user along with the trustworthiness of the website and confidence of facts which outperforms the existing methods. Our results show how the proposed recommender system performs better in predicting the next request of web users.Keywords

A new approach is used to design the printed Band pass Filtering Antenna. Multifunction, multi-use components with design of miniaturization are in considerable demand in wireless communication systems. In these systems, both antennas and filters are usually larger components compared to other components. A single compact module can be designed to provide both the desired filtering and radiating performances. The microstrip parallel line coupled band pass filter with fractal antenna integration approach reduces the integrated antenna system size and the transmission loss between the filter and the antenna and is used in WLAN, Bluetooth and WIMAX. The fractal antennas with integrated parallel line coupled band pass filter are printed on the same layer. The impedance between the antenna and the filter is optimized to improve the performance of the system without restricting it to 50Ω.

In order to study and evaluate the suitability method of predicting the long term adhesion properties of patches to human skin is the biggest challenges in the medical sectors. adhesion to the skin is strictly linked to the efficiently and safety of the therapeutic treatment, now-a- days numerous report of in vivo adhesion lacking are still addressed to regulatory agencies. In real time health care system involving human skin an adhesion patch need to be integrated into diagnostic device. In medical field it is efficient to provide a patch adhesive capacity. Our motive is to develop the patch adhesion tester to determine adhesiveness of the patch. When the patch is given to the proposed tester then the measured values of the given patch will be displayed.Keywords

Increasing global competition in textiles has created many challenges for textile researchers and industrialists. The rapid growth in technical textiles and their end-uses has generated many opportunities for the application of innovative finishers. The population explosion and the environmental pollution in recent years have forced researchers to find new health and hygiene related products for the wellbeing of mankind. The threats caused by microbes are numerous and the problem is aggravated even more in tropical and subtropical regions. Pathogenic microorganisms transfer infectious diseases and cause lung related disorders. Today, much is talked about ‘prevention is better than cure’ using natural and artificial wearing suitable clothing. Recently, there has been upsurge interest in apparel technology all over the world for much demanding functionality of the products like wrinkle resistance, water repelling, fade resistance and resistance to microbial invasion. Among these, development of antimicrobial textile finish is highly indispensable and relevant since garments are in direct contact with human body. This paper deals with the application of natural oils and their antimicrobial property.
