Cloud Computing is being used widely all over the world, as it provides benefits to the users like cost saving and ease of use. The research work focuses on the study of task scheduling mechanism in cloud. The main goal is to reduce the power consumption by datacenters. Energy efficient scheduling of workload help to reduce the consumption of energy in datacenters thus helps in better usage of resources. An improved power saving algorithm is proposed by combining the task classification along with VM skewness algorithm with different scaling options. Skewness is used to quantify the unevenness in utilization of multiple resources on the server. Our purposed algorithm calculate the skewness factor of all Virtual Machines and based upon its value. The proposed approach is performing and shows a decrease in response time, waiting time, processing cost and overall electrical power consumed. The study can be further extended by applying the proposed algorithm on actual Cloud Computing environment and we can also integrate various energy saving technologies into data centers to reduce energy consumption.</p> Sukhbhinder Kaur, Mr. Navtej Singh Ghumman ##submission.copyrightStatement## http://creativecommons.org/licenses/by/4.0 http://cirworld.com/index.php/ijct/article/view/6416 Sun, 22 Oct 2017 05:24:06 +0000 Image Processing: Capturing Student Attendance Data http://cirworld.com/index.php/ijct/article/view/6390 <p>Role of the student attendance record is very important in the primary, secondary,&nbsp;and tertiary education. The purpose of this record is monitoring student activity in&nbsp;the teaching and learning process and regarded as one of the important learning&nbsp;assessments. Moreover, a data processing for recording the student attendance is&nbsp;currently done in various ways such as fingerprint, radio frequent identification&nbsp;(RFID), facial recognition system, android-based application, and others.&nbsp;However, many conventional ways (i.e., using paper-based system) are still used,&nbsp;especially in Indonesia. This is because several universities still rarely have&nbsp;enough funds for developing innovative systems. In this research, the image&nbsp;processing application for capturing student attendance data was built. The&nbsp;objective of this research was to provide an efficient alternative to monitor student&nbsp;activities in teaching and learning process. The image processing produced the&nbsp;information related to student attendance by scanning the attendance file through&nbsp;jpg/jpeg using learning vector quantization (LVG) as the process model.</p> Hendra - Kurniawan, Melda Agarina, Suhendro Yusuf Irianto ##submission.copyrightStatement## http://creativecommons.org/licenses/by/4.0 http://cirworld.com/index.php/ijct/article/view/6390 Wed, 25 Oct 2017 16:18:40 +0000 DESIGN OF WEBSITE-BASED INFORMATION SYSTEM FOR EDOCUMENT ADMINISTRASI IN THE COMMUNITY SERVICE UNIT (A Case Study at Rajabasa District) http://cirworld.com/index.php/ijct/article/view/6396 <p>District office is one of the government agencies. This office certainly produces documents in every administrative process and policy. The document management provides a good solution for each document in order to be accessed and used by users. The improper document management causes difficulty to find the needed documents. Moreover, the document is very difficult to access because it is only kept by certain people for various reasons. Besides, the document is also public rights that should be accessed by many people. An Act number14 in 2008 on Public Information Disclosure indicates that the document is a certain entity to reduce a public dispute so that it is mandatory matter that must be done. Under this condition, it is expected that the document must be stored in the websitebased application to allow all parties to easily access the document stored.</p> Ochi Marshella Febriani, Tri Wahyuni, Suhendro Yusuf ##submission.copyrightStatement## http://creativecommons.org/licenses/by/4.0 http://cirworld.com/index.php/ijct/article/view/6396 Wed, 01 Nov 2017 07:28:06 +0000 AN IMPROVED RESOURCE ALLOCATION STRATEGY BASED ON PACKAGE LEVEL ACCESS IN CLOUD ENVIRONMENT http://cirworld.com/index.php/ijct/article/view/6440 <p>Cloud computing is an emerging field of computer science, where heterogeneous services such as applications, servers and storage are delivered to an individual or organization's computer and devices through the Internet. In the proposed research work, a load balancing algorithm is designed, to provide proper utilization of all resources while processing the requests received from the users. We have implemented the ‘package’ level access at the Virtual Machines. We have proposed three types of packages like basic, medium and premium according to the requirements of the Cloudlets. In the basic package, we have the Virtual Machines with low capacity and in the premium package we are having the Virtual Machines with higher capacity, whereas the medium is of intermediate capacity of MIPS and RAM. In the proposed approach, the capacity, status and current load of every Virtual Machine is computed before allocating the new request of the user. Different parameters like waiting time, execution time and turnaround time of the Cloudlets are computed and analyzed. The proposed research provides the anticipated results with the implementation of the proposed algorithm. Compared with the other job scheduling algorithms, the proposed load balancing algorithm can outperform them in circumstances where the load and Virtual Machines are heterogeneous.</p> Rajveer Kaur, Mr. Navtej Singh Ghumman ##submission.copyrightStatement## http://creativecommons.org/licenses/by/4.0 http://cirworld.com/index.php/ijct/article/view/6440 Sat, 04 Nov 2017 15:02:34 +0000 A NOVEL APPROACH OF CLUSTERING FOR ENHANCED LIFETIME IN WIRELESS SENSOR NETWORK http://cirworld.com/index.php/ijct/article/view/6454 <p>Wireless sensor network has revolutionized the way computing and software services are delivered to the clients on demand. Our research work proposed a new method for cluster head selection having less computational complexity. It was also found that the modified approach has improved performance to that of the other clustering approaches. The cluster head election mechanism will include various parameters like maximum residual energy of a node, minimum separation distance and minimum distance to the mobile node. Each CH will create a TDMA schedule for the member nodes to transmit the data. Nodes will have various level of power for signal amplification. The three levels of power are used for amplifying the signal. As the member node will send only its own data to the cluster head, the power level of the member node is set to low. The cluster head will send the data of the whole cluster to the mobile node, therefore the power level of the cluster head is set to medium. High power level is used for mobile node which will send the data of the complete sector to the base station. Using low energy level for intra cluster transmissions (within the cluster) with respect to cluster head to mobile node transmission leads in saving much amount of energy. Moreover, multi-power levels also reduce the packet drop ratio, collisions and/ or interference for other signals. It was found that the proposed algorithm gives a much improved network lifetime as compared to existing work. Based on our model, multiple experiments have been conducted using different values of initial energy.</p> Chamanpreet Kaur, Vikramjit Singh ##submission.copyrightStatement## http://creativecommons.org/licenses/by/4.0 http://cirworld.com/index.php/ijct/article/view/6454 Mon, 13 Nov 2017 15:36:38 +0000 Concept and Dimensions of Web 4.0 http://cirworld.com/index.php/ijct/article/view/6446 <p>Web 4.0 is a new evolution of the Web paradigm based on multiple models, technologies and social relationships. The concept of Web 4.0 is not totally clear and unanimous in literature, because it is composed by several dimensions. In this sense, this study uses a systematic review approach to clarify the concept of Web 4.0 and explore its various dimensions, analyzing if they have elements in common. The findings indicate that the number of studies published from 2009 to 2017 on this field significantly increased, having reached a peak in 2014. Furthermore, we identified five dimensions associated with the Web 4.0 paradigm, in which the terms “pervasive computing” and “ubiquitous computing” are the most widely used in the literature. On the other side, terms such as “Web 4.0”, “symbiotic Web” and “Web social computing” are not often used.</p> Fernando Luis Almeida ##submission.copyrightStatement## http://creativecommons.org/licenses/by/4.0 http://cirworld.com/index.php/ijct/article/view/6446 Thu, 23 Nov 2017 15:01:46 +0000
