<![CDATA[The modern electronic age consists of many new approaches for the communication among the humancivilizations and the AD HOC network is one of the successful self-configuring and infrastructure-lesscommunicating approach. Mobile ad hoc networks (MANETs) comprised of mobile nodes organize themselves insuch a manner that the can move freely inside the network and frequently change their position. Open architectureand dynamic nature of the network enhance its use in multimedia applications that needs graphics, audio, data,image, video and animation. Now a day?s the increasing use of multimedia and Internet technology needs quality ofservice (QoS) in MANETs in order to provide better service for the companies. This type of applications lendsthemselves well to multicast operations. As multicasting supports group oriented computing it can improve the QoSof the wireless medium by means of sending multiple copies of packets by exploring the internet broadcast propertiesof wireless transmission. Hence QoS multicasting plays a great role in MANETs for multimedia applications.However it is very difficult and challenging task to provide QoS multicasting. With unique features and by means ofdifferent recovery mechanisms, many researchers have been proposed various QoS based multicasting routingprotocols for MANETs. In order to assist QoS multicasting routing protocols design for MANETs, we characterizethe taxonomy of the multicast routing protocols and design features in this paper.]]>

<![CDATA[Software Defined Network (SDN) decouples the responsibilities of route management and datatransmission of network devices present in network infrastructure. It integrates the control responsibility at thecentralized software component which is known as controller. This centralized aggregation of responsibilities mayresult the single point of failure in the case malicious attack at the controller side. These attacks may also affect thetraffic flow and network devices. The security issues due to such malicious attacks in SDN are dominating challengesin the implementation and utilization of opportunities provided by this new paradigm. In this paper we haveinvestigated the several research papers related to proposal of new research trends for security and suggestionswhich fulfil the security requirements like confidentiality, integrity, availability, authenticity, authorization,nonrepudiation, consistency, fast responsiveness and adaptation. We have also investigated the new future researchfor creating the attack free environment for implementing the SDN.]]>

<![CDATA[Automatic identification systems represent a wide classification of devices used primarily in commercialsettings for inventory/logistics control. Familiar examples of such devices are bar codes, magnetic strips, smartcards, RFID (Radio frequency identification) and biometric and voice recognition. Security is especially lax in lowpowered RF (radio frequency) systems communicating through an unsecured radio wave channel. Security representsa critical component for enabling the large scale adoption of automatic identification systems. Providing an effectivesecurity solution for low powered systems is a major area of concern; it directs research towards ?powerconsumption aware? computations in security solutions. This paper proposes a Lightweight Inter-ZonalAuthentication Protocol for moving objects in low powered RF systems. Formal validation and a thorough analysisof the protocol in SPAN security tool reveals its effectiveness and resiliency to attacks?eaves dropping, reader andtag impersonation, replay and desynchronization.]]>

<![CDATA[With the enormous growth in the Internet and network, data security has become an inevitable concern forany organization. From antecedent security has attracted considerable attention from network researchers. In thisperspective many possible fields of endeavour come to mind with many cryptographic algorithms in a broader way,each is highly worthy and lengthy. As society is moving towards digital information age we necessitate highlystandard algorithms which compute faster when data size is of wide range or scope. On survey, numerous sequentialapproaches carried out by symmetric key algorithms on 128 bits as block size are ascertained to be highly insecurable and resulting at a low speed. As in the course the commodities are immensely parallelized on multi coreprocessors to solve computational problems, in accordance with, propound parallel symmetric key based algorithmsto encrypt/decrypt large data for secure conveyance. The algorithm is aimed to prevail by considering 64 character(512 bits) plain text data, processed 16 characters separately by applying parallelism and finally combine each 16-character cipher data to form 64-character cipher text. The round function employed in the algorithm is verycomplex, on which improves efficacy.]]>

<![CDATA[Mobile Ad-hoc Network is a non-secure wireless network which has no infrastructure, dynamical topologyin which the nodes can move anywhere, may join or leave the network through multi-hop communication. In clusternetwork, all the nodes can select one Cluster Head for transmission of data to another Cluster Head through gatewayswhich is mainly used for saving energy of each node. Intelligent agents are used for collecting secure data fromneighboring nodes and inform to the trusted agent in clustered networks. Security plays major role in wireless medium.Detecting malicious node is also causing a major concern to damage the data packets. To avoid this problem of enteringmalicious node in networks and non-secured data, agents based trusted revocation in clustering mobile ad-hoc networkfor improving security with Certificate Authority to improve the network performance like high throughput, less latencytime and improved certificate revocation time using ns2 simulators.]]>

<![CDATA[One of the very efficient and resource conservative image processing methodology is with the help of bilateralfilters. This technique filters the image without the help of edge smoothing but it does employs spatial averaging in anon-linear way. The filtering technique discussed above is very much dependent on the parameters of its filters. A veryslight change in filter parameter values effects the outputs and results in a most drastic manner. In this paper, theauthor has worked on two contributions. In the applications concerning image denoising, the author has contributedin study of the parameter selection of bilateral filters which are optimal in nature. The contribution number two isabout extending the present work i.e. extension of the filters which are bilateral in nature. In this process, the bilateralfiltering of images is applied to the lower frequency sub-bands which is also known as approximation sub-band. Thissub-band is obtained by using the wavelet transformations. Hence, a new framework for image denoising will becreated which will be combination of multiresolution bilateral filtering and wavelets transformation techniques. As amatter of fact, this combination is efficient in contradicting noise from an image.]]>

<![CDATA[The delivered effort in this manuscript is grounded on NS-2 (The Network Simulator 2) to implement thecongestion control process of classic TCP (Transmission Control Protocol), with new congestion control mechanism.In this paper, a novel congestion control algorithm is offered, which contains of slow-start and congestion avoidancemechanisms. The proposed slow-start algorithm assumes a duplicating and an interpolating approach to the congestionwindow (cwnd) for each increment instead of the exponential increment used by other TCP source variants such asReno, Vega, Tahoe, Newreno, Fack, and Sack. Furthermore, the enhanced congestion avoidance algorithm is built byusing an improved Additive Increase Multiplicative Decrease (AIMD) algorithm with multi TCP flow facility, to providean enhanced congestion control algorithm with some valuable properties to improve TCP routine for high speedprotocols. The improvement strategy based on merging of slow start, congestion avoidance mechanism that are usedin TCP congestion control, to create a new AIMD algorithm with a new relationship between the pair parameters aand b. This paper is also involved in the creation of rapid agent in NS-2 models designed to identify the modified TCPand to configure the NS-2 platform. A fast TCP also includes an innovative scheme to slow the rapid start to help TCPto start faster through the high speed networks and also to postpone the congestion state as much as possible.]]>
