This paper deals with the advanced and developed methodology know for cancer multi classification using an Extreme Learning Machine (ELM) for microarray gene expression cancer diagnosis, this used for directing multicategory classification problems in the cancer diagnosis area. ELM avoids problems like local minima; improper learning rate and over fitting commonly faced by iterative learning methods and completes the training very fast. We have evaluated the multicategory0 classification performance of ELM on benchmark microarray data sets for cancer diagnosis, namely, the Lymphoma data set. The results indicate that ELM produces comparable or better classification accuracies with reduced training time and implementation complexity compared to artificial neural networks methods like conventional back-propagation ANN, Linder's SANN, and Support Vector Machine. ©2010 IEEE.

A Mobile Ad Hoc Networks (MANET) is a self-configuring network connected by wireless links and they are a collection of mobile nodes which communicate over radio. There are various routing protocols available for MANETs. Broadly they are classified into three. One is Proactive protocol, each node maintains one/more tables containing routing information to every node in the network. All nodes update these tables so as to maintain a consistent and up-to-date view of the network. Two is Reactive protocols, all up-to-date routes are not maintained at every node. Instead the routes are created as and when required. The route remains valid till the destination is reachable or until the routes no longer needed. Ant colony optimization (ACO) depicts a proactive behavior, is a metaheuristic for solving hard combinatorial optimization problems inspired by the indirect communication of real ants. Multi Agent System (MAS) depicts a reactive behavior, is used to solve problems that are difficult or impossible for an individual agent or a monolithic system to solve. Three is Hybrid Protocols, try to profit the advantages of both reactive and proactive protocols and combine their basic properties into one. They have the potential to provide higher scalability than pure reactive or proactive protocols. In this paper, a hybrid routing scheme that combines the best properties of ACO and MAS is proposed. The proposed hybrid protocol reduces the end-to end delay, minimizes the packet loss and results in maximum packet delivery ratio. © 2014 IEEE.

The conversion of regular expressions into finite state automata and finite state automata into regular expression is an important area of research in automata theory. The notion of derivatives of regular expressions has been introduced to make the construction of finite state automata from regular expressions in a natural way. Recently, a general structure has been proposed to find the derivatives of regular expressions to reduce the difficulties arising out of the earlier methods. In this paper, some properties of the derivatives of regular expressions, the quotient language, and how the derivatives are found through a general structure, have been discussed in detail. © 2016 Inderscience Enterprises Ltd.

In the last two decades, there is magnetism in the use of internet and Communication Technology in the field of Mobile Ad Hoc Network. It motivates the researchers to turn over in those areas. There were some algorithms proposed for electing the efficient Clusterheads. Clusterheads are having more responsibilities like to minimize the re-affiliation, topology changes, and the stability of the on demand networks. We proposed a new efficient clusterhead selection algorithm based on the maximum weight in which it takes consideration of five different weight parameters. In this paper we analyses the clusterhead changes, energy consumption, life time of the network and end to end delay of the nodes. The experimental result also shows that proposed algorithm is better than the existing Weighted Clustering Algorithms. © 2011 IEEE.

Spam filters are the most used software tool used by businesses and individual to block spam mails entering into their mail boxes. Until recently, majority of research effort was expended on controlling text-based spam emails. However, the past few years have envisaged a novel approach, where the spammers embed the text message into an image. Thus, the anti-spam filtering research is forced to move from text-based techniques to image-based techniques. Spam and the spam blockers designed to combat it have spawned an upsurge in creativity and innovation. Many software developers are developing new and every more effective spam filtering software. All the methods have a common dream that is to eliminate 100% of the spam, which is still not a reality. To reduce the gap between this reality and dream, researchers have proposed many different types of spam filters and this paper provides a review of them. © 2013 IEEE.

The embedding of low cost electroencephalogram (EEG) sensors in wireless headsets gives improved authentication based on their brain wave signals has become a practical opportunity. In this paper signal acquisition along with effective multi-channel selection from a specific area of the brain and denoising using AWICA methods are proposed for EEG based personal identification. At this point, to develop identification system the steps are as follows. (i) the high-quality device with the least numbers of channels are essential for the EEG signal acquisition and Selecting the equipment and verdict the best portions on the scalp is the primary step. (ii) Scrutiny of the acquired EEG signals and de-noising from EMG, ECG, EOG Signals and power line artifacts using AWICA (iii) Obtain the features from the Enhanced EEG signals by Wavelet Transform (WT) and LS-SVM Classification in the MATLAB Environment. Based on the outcome, there is possibility for implementation of an EEG based Practical biometric system.

Since the AOMDV routing protocol selects multiple node disjoint paths based on minimal hop count, the link failures and route breaks occurred in highly dynamic ad hoc networks. For eliminating such problems, we proposed a novel link quality based multipath routing protocol called Link Quality Based Multipath Routing (LQBMR) protocol which is the extension of a well known AOMDV routing protocol. The proposed protocol finds multiple link reliable paths using Path-Link Quality Estimator (P-LQE) such as Cumulative Expected Transmission Count (CETX). The LQBMR protocol uses only CETX instead of hop count as path metric for determining more link reliable paths between any source and destination pair for data transmission. We have evaluated the performance of LQBMR protocol using NS 2.34 and compared it with AOMDV routing protocol. The LQBMR protocol reduces the routing overhead, packet loss ratio, normalized routing overhead and energy consumption. It also increases the packet delivery ratio and throughput. From the simulation results, it is found that the LQBMR protocol has performed better than AOMDV routing protocol. © 2005 - 2014 JATIT & LLS. All rights reserved.

Bandwidth scarcity is a major drawback in multi-hop ad hoc networks. When a single-interface single-channel (SISC) approach is used for both incoming and outgoing traffic, the bandwidth contention between nodes along the path has occurred as well as throughput is degraded. This drawback is overwhelmed by using multi-interface multi-channel (MIMC) approach as well as some of the quality-of-service (QoS) requirements have been enhanced. In this paper, we have applied MIMC approach to ad hoc on-demand multipath distance vector (AOMDV) routing protocol, called AOMDV-MIMC routing protocol, and its performance is compared with AOMDV routing protocol. The simulation results show the network lifetime, throughput, and packet delivery ratio of AOMDV-MIMC routing protocol have been tremendously improved than the AOMDV routing protocol. © Springer India 2015.

Reliable data transmission among mobile nodes in highly dynamic ad hoc networks was not ensured by AOMDV routing protocol due to the selection of the multiple node disjoint paths based on only minimal hop counts that lead to link failures and route breaks. For eliminating such problems, we propose an improved ad hoc on-demand multipath routing protocol called Link Reliable Multipath Routing (LRMR) protocol. It finds multiple link reliable paths between any source and destination pair for data transmission using two metrics such as Path Length and Path-Link Quality Estimator (P-LQE). We evaluate the performance of LRMR using NS 2.34 with varying network flows under random waypoint mobility model and compare it with AOMDV routing protocol in terms of Quality of Service (QoS) requirements. The LRMR reduces 9% of routing overhead, 18% of packet loss ratio, 13% of normalized routing overhead and 7% of energy consumption than AOMDV routing protocol. It also increases 9% of packet delivery ratio and 2% of throughput than AOMDV routing protocol. From our simulation results, we show that the LRMR protocol outperforms AOMDV routing protocol. © 2015 IEEE.
