To deal with the increasing demand for heterogeneity, a new authentication protocol have been proposed to increase the efficiency of interworking wireless security; they enable mutual authentication among users in inter and intra domain networks. However, to expand inequitable distribution of heterogeneous networks, an intruder may impersonate a legitimate user's signal. Therefore, a secure legitimate user detection method that can distinguish an allowed user's gesture from an attacker's gesture is needed. To generate a trust relationship between user, base station and home network, a novel approach for authenticating protocol which kowtow heterogeneity requirements. It integrates cryptographic credentials, public/private key of base station, random number challenges to facilitate user detection in the presence of intruders. The random number serves as an association, to enable a home network to verify equivalent certificate carried by the base station per user's request. A key involvement in this paper is a new physical layer authentication technique that enables the base station authentication signals from its associated users. © 2015 IEEE.

Real-time multimedia communication is more tolerant to changes in bandwidth and delay. To overcome quality of service (QoS) constraint in the network, in this paper we propose to develop a bandwidth and delay aware routing protocol for real time traffic in MANET. This technique involves construction of bandwidth and delay aware paths between a source-destination pair. Initially the bandwidth availability and expected total delay are estimated for each path and the source selects the optimal path with maximum bandwidth and minimal delay. By simulation results, we show that the technique is more efficient to overcome QoS constraint. © 2013 Praise Worthy Prize S.r.l. - All rights reserved.

A statistical approach, based on full range Gaussian Markov random field model, is proposed for texture analysis such as texture characterization, unique representation, description, and classification. The parameters of the model are estimated based on the Bayesian approach. The estimated parameters are utilized to compute autocorrelation coefficients. The computed autocorrelation coefficients fall in between -1 and +1. The coefficients are converted into decimal numbers using a simple transformation. Based on the decimal numbers, two texture descriptors are proposed: (i) texnum, the local descriptor; (ii) texspectrum, the global descriptor. The decimal numbers are proposed to represent the textures present in a small image region. These numbers uniquely represent the texture primitives. The textured image under analysis is represented globally by observing the frequency of occurrences of the texnums called texspectrum. The textures are identified and are distinguished from untextured regions with edges. The classification analyses such as supervised and unsupervised are performed on the local descriptors. © 2013 Copyright Taylor and Francis Group, LLC.

Wireless sensor networks (WSN) are becoming an inevitable solution in industries for its automation and monitoring applications. Sensor nodes in WSN are deployed in fields with limited power. By nature these nodes are left unattended after deployment. This raises the importance of developing efficient algorithms which are capable of increasing the network lifetime by consuming less energy during the operations. This paper proposes a hybrid clustering energy aware routing protocol (H-CERP) for heterogeneous WSNs. H-CERP is designed to form efficient clusters with less cluster head count than the optimal estimation and uses multihop communication with gateway nodes to communicate with the base station. This novel approach makes our system more advantageous where the network lifetime and coverage of sensors are much vital at no additional cost. By deploying H-CERP in designed environment the results extracted shows promising results in terms of energy consumption, residual energy and lifetime of nodes when compared with generic methods like LEACH, PEGASIS and other recent techniques. © 2016 Springer Science+Business Media New York

Artificial Intelligence and web when amalgamated, it may produce miracle in terms of semantic web. E-learning works efficiently only when E-Content preparation is need based, searchable through semantic similarity between keywords. This paper describes a e-content/e-book preparation from existing available contents on a selected topic/topics, based on a semantic similarity between particular keywords. Accurately measuring semantic similarity between two words remains a challenging task. We propose an empirical method to estimate semantic similarity using page counts and text snippets. © 2012 IEEE.

Generally, due to unbalanced load allocation, congestion results in mobile adhoc networks. By keeping dynamic metrics such as network load, will result in load balanced routing thus avoiding congestion. The resources allocated for real-time traffic result in wastage of resources, if there is no such traffic is available for a particular period. In this paper, we propose a new distributed load based routing algorithm intended for a variety of traffic classes to establish the best routing paths. The proposed algorithm calculates the cost metric on the basis of the load on the links. The dynamic traffic can be classified as multimedia and normal traffic. Multimedia traffic is considered as high priority and normal traffic as low priority. The routing of high priority traffic is performed over the lightly loaded links, in such a manner that the links with lighter loads are chosen instead of links with heavier-loads. In addition, the resources can be shared between the high priority traffic's path and low priority traffic. In the absence of multimedia traffic, the lightly loaded path can be utilized by normal traffic. © EuroJournals Publishing, Inc. 2011.

In Mobile Ad hoc Networks (MANET), reliability in real time data transmission can be assured by confirming the connectivity of the network. Since, MANETs are characterized by dynamic topology changes; the established connection must be monitored for its consistency. In order to provide and maintain connectivity, in this paper, we propose a reliable real time data transmission technique in MANET using connection possibility. In this technique, a path with high connection possibility is elected as the main path using transmission path discovery mechanism. In addition to this, connectivity maintenance phase is initiated during link failures and delayed replies. In this phase, the path with long link expiration time is chosen for data transmission. By simulation, we show the performance of our technique. It provides reliable connectivity for real time data transmission. © 2005 - 2013 JATIT & LLS. All rights reserved.

In this paper, the performance of divide-by-128/129 and 256/257 dual modulus prescalers has been analyzed. Designing a dual modulus prescaler is the most challenging issue in the high speed frequency synthesizers, since it operates at very high input frequency typically in the order of GHz. Also, power consumption is a key consideration in the prescaler design. In this work, the dual modulus prescalers were designed using true single phase clock (TSPC) based D-Flip Flops which consumes less power compared to other flip flop architectures. The prescalers were implemented in 90nm CMOS process with a supply voltage of 1.2V. The experimental result shows that, the dual modulus prescaler using TSPC flip flops implemented in 90nm CMOS process with a supply voltage of 1.2V is capable of operating up to ∼5GHz frequency. © 2016 IEEE.
