Improvised Scout Bee Movements in Artificial Bee Colony

By Tarun Kumar Sharma Millie Pant

DOI: https://doi.org/10.5815/ijmecs.2014.01.01, Pub. Date: 8 Jan. 2014

In the basic Artificial Bee Colony (ABC) algorithm, if the fitness value associated with a food source is not improved for a certain number of specified trials then the corresponding bee becomes a scout to which a random value is assigned for finding the new food source. Basically, it is a mechanism of pulling out the candidate solution which may be entrapped in some local optimizer due to which its value is not improving. In the present study, we propose two new mechanisms for the movements of scout bees. In the first method, the scout bee follows a non-linear interpolated path while in the second one, scout bee follows Gaussian movement. Numerical results and statistical analysis of benchmark unconstrained, constrained and real life engineering design problems indicate that the proposed modifications enhance the performance of ABC.

Radio Frequency Identification (RFID) is a method for automated identifying objects. One of the problems of this technology is its security. RFID tags include resource limitation; therefore, the system designers cannot implement complex circuits to enhance their security. Usually the symmetric and asymmetric encryption methods increase resources and cost. Because it is believed to increasing security is inconsistent with the simplicity, the researchers mostly use one-way encryption methods. In this paper, we propose a mutual authentication protocol based on public key cryptography. The used encryption method includes high security and low complexity. This protocol performs in few steps and is suitable for portable devices with power limitation. In terms of security, the proposed protocol is robust against known attacks. In addition, we prove the protocol is secure by an analytical method.

Highlighting the role of Requirement Engineering and User Experience Design in Product Development Life Cycle

By Ambreen Nazir Ayesha Raana Nadeem Majeed

DOI: https://doi.org/10.5815/ijmecs.2014.01.04, Pub. Date: 8 Jan. 2014

Product Development Life Cycle (PDLC) has been evolving from last decade from side to side unremitting progression of finest practices, process models and advance life cycles. Already present development models like rational unified process, waterfall model and spiral model have facilitated the people, who are being practicing the new models, to incalculably make their products better on the competence and effectiveness. Nevertheless, there is a need to quantify the product quality with the factors that are away from any traditional criterion like maintainability, reliability and the rest. Accomplishing a product that is technically strong only contributes a little part in sensational product market situation, but to what extent the product fulfills the major needs of the users reveals the real success of the product. Requirement Engineering (RE) and User Experience Design (UED) together make available the comprehended user requirements to product development team for successful implementation of product and further help the development team to resolve any problem that takes place. The paper emphasizes on the role of RE and UED during PDLC and discusses the challenges that comes out after coalition of RE and UED in product development. In the closing section some points are listed for determining these challenges.

Continuous miniaturization of mobile devices has greatly increased its adoption and use by people in various facets of our lives. This has also increased the popularity of face recognition and image processing. Face recognition is now being employed for security purpose opening up the need for further research in recent time. Image compression becomes useful in cases when images need to be transmitted across networks in a less costly way by increasing data volume while reducing transmission time. This work discusses our findings on image compression and its effect on face recognition systems. We studied and implemented three well known face recognition algorithms and observed their recognition accuracy when gallery / probe images were compressed and/or uncompressed as one would naturally expect. For compression purposes, we adopted the JPEG and JPEG2000 coding standard. The face recognition algorithms studied are PCA, ICA and LDA. As a form of an extensive research, experiments conducted include both in compressed and uncompressed domains where the three algorithms have been exhaustively analyzed. We statistically present the results obtained which showed no significant depreciation in the recognition accuracies.

Design Intelligent Robust Back stepping Controller

By Zahra Esmaieli Farzin Piltan Meysam Kazeminasab Ali Reza Salehi Mahdi Mirshekaran

DOI: https://doi.org/10.5815/ijmecs.2014.01.06, Pub. Date: 8 Jan. 2014

The increasing demand for multi-degree-of-freedom (DOF) continuum robot in presence of highly nonlinear dynamic parameters in a number of industries has motivated a flurry of research in the development of soft computing nonlinear methodology. The robust backstopping controller proposed in this research is used to further demonstrate the appealing features exhibited by the continuum robot. Robust feedback controller is used to position control of continuum robot in presence of uncertainties. Using Lyapunov type stability arguments, a robust backstopping controller is designed to achieve this objective. The controller developed in this research is designed into two steps. Firstly, a robust stabilizing torque is designed for the nominal continuum robot dynamics derived using the constrained Lagrangian formulation based on modified PD backstopping controller. Next, the fuzzy logic methodology applied to it to solution uncertainty problem. The fuzzy model free problem is formulated to estimate the nonlinear formulation of continuum robot. The eventual stability of the controller depends on the torque generating capabilities of the continuum robots.

By Sonali Swetapadma Sahu Manjusha Pandey

DOI: https://doi.org/10.5815/ijmecs.2014.01.07, Pub. Date: 8 Jan. 2014

A wireless sensor network (WSN) is a wireless network consisting of spatially distributed autonomous devices using sensors to monitor physical or environmental conditions.WSN is a fluorishing network that has numerous applications and could be used in diverse scenarios. DDoS (Distributed Denial of Service) is an attack where a number of compromised systems attack a single target, thereby causing denial of service for users of the targeted system. The flood of incoming messages to the target system essentially forces it to shut down, thereby denying service to the system to legitimate users.Not much research work has been done in DDoS in WSN.We are conducting a review on DDoS attack to show its impact on networks and to present various defensive, detection and preventive measures adopted by researchers till now.
