Nowadays, most of paper based exams are converted to computer based exams. Such conversion requires a significant robust security issues. The security issues are not limited to the authentication of the exam invigilators, and provided identification card. Improving the computer based exams authentication security is a challenging task, where focusing on user authentication ways is the main core to have a robust secure exams. This paper introduces a new methodology of authentication based on biometric iris recognition system for Qiyas exams in Kingdom of Saudi Arabia. Actually, this paper proposed a two level of authentication in order to ensure the process of verification in internet computer based exams.

Various microcells have high traffic density during peak hours, the problems are further exacerbated by the traffic overloading in downtown areas at peak hours. The reliable and efficient communication demands unnoticed handoff to the user without deteriorating the signal strength. Current cellular system exhibits a varying traffic conditions depending upon the corresponding variations in population which is low in rural areas and high in downtown areas. The traffic density becomes even higher at peak hours and low at night hours. The acceptable service quality demands optimum use of frequency spectrum for obtaining maximum traffic throughput. The efficient allocation of channels on need basis can be one of the solutions for efficient traffic management during peak hours. In Flexible Channel Allocation scheme (FlCA), the available channels are divided in fixed and flexible set channels. Fixed set channels are normally assigned to all the cells and the number of channels is decided by the approximate calculated load of particular cell that typically suffices the traffic load of cell. The flexible channels are assigned to those cells whose channels are inadequate under increased traffic load conditions. These channels are assigned in accordance with demand of increased traffic loads. Fuzzy logic approach being flexible is explored for assigning these flexible channels for enhanced QoS.

Biometric technology is now used for employees time management attendance system because it has ability to recognize peoples unique physiological characteristics. Because of multiple benifits of Biometric attendance system it has gained high popularity in the market. Biometrics attendance system is extremely useful in helping business community feel secure by eliminating employees time theft, as it relies on ones personal characteristics that vary between individuals. Since biometrics characteristics cannot be duplicate, it prevents punching on behalf of a co-worker working in the same company. The manual practice of attendance system is time consuming and needs full time personal monitoring whereas biometric attendance saves employee time, decreases staffing overhead and provides accurate labour data to payroll system to effectively manage business operations and thereby increase productivity. Moreover the biometric attendance system has brought transperancy and enhanced the work culture in the system. We will explore various advantages and disadventages of implementation of the biometric attendance system to a big organization, or small entrepruner or unit and the necesary measures for its efficient implementation. oriental Journal of Computer Science and Technology Journal Website: www.computerscijournal.org ISSN: 0974-6471, Vol. 11, No. (1) 2018, Pg. 50-54

Cognitive radio (CR) is a novel technology to resolve the issue of underutilization of wireless spectrum. Quality of service (QoS) provisioning in CR networks to large number of traffic as per their need is not an easy task since no wireless spectrum is available on permanent basis for its operation. In this paper, few critical QoS parameters namely dynamic-availability-ofidle-channels (avail-idle-channel), expected-holding-time-of-idle-channel (HT-idle-channel) and user-mobility are chosen to analyze their impact over quality of service of the communicating cognitive users using rule-based fuzzy decision-making system. The results indicate the relationship of chosen parameters over the QoS of the communicating cognitive users. oriental Journal of Computer Science and Technology Journal Website: www.computerscijournal.org ISSN: 0974-6471, Vol. 11, No. (1) 2018, Pg. 55-63

The purpose of the present research is to propose a detailed analysis of a fragment of a passive memristor memory crossbar. For computer simulations a previously proposed by the authors in another paper nonlinear dopant drift memristor model with a modified window function is now applied. The results obtained by the simulation are compared with experimentally recorded current-voltage relationships and with these derived by the use of several basic memristor models as well. A relatively good coincidence between the results is established. The fragment of a memristor memory crossbar is simulated for the procedures of writing, reading and erasing information in the memristor cells. The effect of the basic memristor parameters, as the ionic drift mobility, the ON and OFF resistances and the physical length of the element on its switching speed is discussed. After a number of simulations, it was established that due to the self-rectifying effect the parasitic sneak paths do not strongly influence the normal operation of the memristor memory crossbar. It is confirmed that the model with a modified Biolek window function proposed in our previous research could be used for simulations of complex memristive electronic circuits for hard-switching. oriental Journal of Computer Science and technology Journal Website: www.computerscijournal.org ISSN: 0974-6471, Vol. 11, No. (1) 2018, Pg. 04-11

Mobile agents are a very novice field with wider scope of research in the stream of a integrated coherent networks, parallel programming, automated learning, remote execution and artificial intelligence. A mobile agent is a representative that is often treated as moving object developed using any object oriented programming language. Using a WFMS is an emerging current trend in modeling, research methodologies and implementing the information/data flow and various related business processes within an organization. Work is often credited as a task, information, a document, data, announcements or a job that passes through different nodes within an organization. The integration of WFMS involves the automation of various processes such as tasks, documents, processed data, and information or rules to accomplish a task. This automation within the technology can be achieved by integration of agent based technology that makes use of Mobile Agent Paradigm. This paper briefs about various features, benefits and role mobile agents in Workflow management system. This also highlights how the implementation of MAWFMS can smoothen and simplifies the workflow managements in multifarious event based environments. oriental Journal of Computer Science and Technology Journal Website: www.computerscijournal.org ISSN: 0974-6471, Vol. 11, No. (1) 2018, Pg. 40-49

Cognitive radio (CR) is a novel technology to resolve the issue of underutilization of wireless spectrum. There exists number of challenges and issues in designing and implementation of the cognitive radio. Extending qualityof-service (QoS) enabled applications to CR network is even more difficult task due to non-availability of the dedicated allocation of idle spectrum. CR imposes peculiar and unique challenges to guarantee quality of service of diverse flows in contrast to other wireless networks. This paper identifies the issues and challenges of QoS provisioning in cognitive radio networks.
