An Optimized Congestion Control and Error Management System for OCCEM

Abstract: In this paper, a new OCCEM congestion control mechanism is introduced in multi-homing mode. Congestion in each route can be avoided or can be controlled, based on an Active Queue Management (AQM) method. Also, routers compute probability of congestion for the sources on the paths and then notify them. Therefore, the sources can adjust their sending rates on each path effectively and if necessary, can switch to an alternate path to prevent congestion. Simulations have been conducted with Opnet linked with NS2. The simulation shows that the new method can decrease packet loss, increase the amount of transmissions and stabilize queue length, as compared with standard OCCEM. Keywords: OCCEM; AQM; congestion control

An Approach for Solving Multiple Travelling Salesman Problem using Ant Colony Optimization

Abstract: Ant Colony Optimization (ACO) is a heuristic algorithm which has been proven a successful technique and applied to a number of combinatorial optimization (CO) problems. The traveling salesman problem (TSP) is one of the most important combinatorial problems. Multiple traveling salesman problem (MTSP) is a typical computationally complex combinatorialOptimization problem, which is an extension of the famous traveling salesman problem (TSP). The paper proposed an approach to show how the ant colony optimization (ACO) can be applied to the MTSP with ability constraint. There are several reasons for the choice of the TSP as the problem to explain the working of ACO algorithms: it is an important NP-hard optimization problem that arises in several applications; it is a problem to which ACO algorithms are easily applied; it is easily understandable, so that the algorithm behavior is not obscured by too many technicalities; and it is a standard test bed for new algorithmic ideas as a good performance on the TSP is often taken as a proof of their usefulness.

A Survey of Virtual Machine Migration Techniques in Cloud Computing

Abstract: Cloud computing is an emerging computing technology that maintains computational resources on large data centers and accessed through internet, rather than on local computers. VM migration provides the capability to balance the load, system maintenance, etc. Virtualization technology gives power to cloud computing. The virtual machine migration techniques can be divided into two categories that is pre-copy and post-copy approach. The process to move running applications or VMs from one physical machine to another, is known as VM migration. In migration process the processor state, storage, memory and network connection are moved from one host to another.. Two important performance metrics are downtime and total migration time that the users care about most, because these metrics deals with service degradation and the time during which the service is unavailable. This paper focus on the analysis of live VM migration Techniques in cloud computing. Keywords: Cloud Computing, Virtualization, Virtual Machine, Live Virtual Machine Migration.

A Scheduling Algorithm to Enhance the Performance and the Cost of Cloud Services

Abstract: Cloud computing is based on the pay-per-use; hence, the price of usage is one of the main factors for cloud services’ customers when selecting the cloud provider to rent the service from. Hence, cloud providers need to provide competitive costs of the services for the users. Therefore, the cloud providers, in addition to optimize the utilization of the resources, aim to provide the service with the competitive cost at the same time. In order to achieve this, there is a need for a new set of economical task scheduling algorithms for the cloud. This paper introduces an algorithm for task scheduling based on assigning priorities for tasks according to their profits, where we provided examples of usage of the algorithm and compared it to some of the traditional cloud scheduling algorithms . Keywords: Cloud Computing, Scheduling, Priority, Resource Utilization.

Design and Implementation of Microcontroller Based Programmable Power Changeover

Abstract: Power failure is a key issue in many developing countries of the world. To sustain development, the need for alternative power supply becomes necessary. Changing between the main supply line and the alternative supply poses yet another problem. Many attempts have been made to develop automatic power changeover but without due consideration of the fact that there could be times when we need to regulate the behavior of the automatic change over. This paper therefore presents the design and construction of microcontroller based programmable automatic power change over. The paper discusses the design, construction and operation of a program controlled power change over system that allows users to select the mode they would prefer to have their change over operate. Three modes were achieved, including auto mode, timed mode and manual mode, which were selected from push buttons. LCD interface was used for the output display. 8051 microcontroller was used to implement the control program while modular methodology was adopted.

Utilizing Divisible Load Scheduling Theorem in Round Robin Algorithm for Load Balancing In Cloud Environment

Abstract: Cloud Computing is a newly paradigm in computing that promises a shift from an organization required to invest heavily for limited IT resources that are internally managed, to a model where the organization can buy or rent resources that are managed by a cloud provider, and pay peruse. With the fast growing of cloud computing one of the areas that is paramount to cloud computing service providers is the establishment of an effective load balancing algorithm that assigns tasks to best Virtual Machines(VM) in such a way that it provides satisfactory performance to both, cloud users and providers. Among these load balancing algorithms in cloud environment Round Robin (RR) algorithm is one of them. In this paper firstly analysis of various Round Robin load balancing algorithms is done. Secondly, anew Virtual Machines (VM) load balancing algorithm has been proposed and implemented; i.e. ‘Divisible Weighted Round Robin(DWRR) Load Balancing Algorithm’. This proposed load balancing algorithm utilizes the Divisible Load Scheduling Theorem in the Round Robin load balancing algorithm. In order to evaluate the performance of this proposed algorithm (DWRR) the researcher used a simulator called CloudSim tool to conduct a test on the performances between the proposed algorithm (DWRR) and the types of Round Robin algorithms. After a thoroughly comparison between these algorithms, the results showed that DWRR outperforms the various types of Round Robin(Weighted Round Robin and Round Robin with server affinity )algorithms in terms of execution time (makespan) with the least complexity.

The Blurred Line between “Long” and “Short”: How the Length of Video Lectures Affects the Viewing Behavior of E-Learners

Abstract: Recent research has focused on the impact of video lectures on students’ academic performance rather than the viewing behavior of learners. In this study, we investigate the learners’ preferences of video lectures in terms of the length as well as the devices used to access the online learning material. We published two versions of video lectures on two YouTube channels. The online material was produced by recording a real face-to-face class context at the Arab Open University. The video recorded material belongs to a first level course offered to students at the Faculty of Computer Studies. The first version of the online lectures comprised 7 videos and is, hence, called long-run version. The second version, termed as short-run version, consisted of 28 video lectures. Video contents are identical in both versions. Total recording time amounted to 528 minutes in both video versions with an average of 75 and 19 minutes in long-run and short-run versions, respectively. We found that though students alternated between the use of mobile phones, tablets and desktops, however, they mainly accessed the online material through desktops. Moreover, students spent a total of 43765 minutes in viewing the long-run videos compared with 4766 minutes spent on the short-run ones. Considering the number of views (3143 for the long-run and 846 views for the short-run videos) yields average viewing times of 13.92 and 5.63 minutes per views for the long-run and short-run videos, respectively. This is interesting, for these results show that students are willing to spend approximately 14 minutes when viewing an approximately 75 minutes long video lecture, but when offered a 22 minutes long alternative, the time they spend in viewing does not exceed 6 minutes on average. Our results imply that students do access the online video lectures for learning purposes. However, more should be done, so as to approach near-optimal lengths of video lectures that facilitate a complete viewing of the learning material.

Confined Routing in Wireless Sensor Networks: A Study on Intended at Motion

Abstract: One of the grave problems after kidney transplantation is the recipient body’s immune rejection of the transplanted organ. T -cells and antibodies attack the organ, which in the worst case can lead to graft failure. Biopsy is an important diagnostic tool to evaluate a rejection episode. TBase© includes a biopsy protocol that can easily be filled out by the physician, which helped to collect and store 1447 biopsy cases in the TBase© database. With respect to different kinds of rejections, there exist some basic rules for the entered data that are enforced during completion of the protocol. Nevertheless, because so much biopsy data was entered in by hand, it was necessary to check the quality and plausibility of existing data with respect to more complex rules that were not enforced during protocol completion. In this paper, we present the process of checking the biopsy data for consistency with complex rules provided by an expert, as well as mining of new rules using interpretable rule-based classification methods. We discovered interesting rules and relationships between features with respect to T-cell mediated rejection (TCMR), antibody-mediated rejection (AMR), interstitial fibrosis and tubular atrophy (IF/TA), and polyoma virus (BKV) nephropathy, with negative results concerning acute tubular necrosis (ATN). The discovered rules further support the quality and plausibility of the data, and open avenues for further research. Keywords: Electronic patient record, nephrology, biopsy, data mining.

Framework to establish offline file sharing in Application as a service layer in cloud computing

Abstract: Term cloud computing has opened entire new domain of computability, reliability and efficiency. Organizations can now focus on providing targeted services to consumers rather than considering infrastructure and resource issues. Cloud consumers can enjoy ease of computing and power of reliability but cloud service providers have to ensure many measures to let cloud services be reality and reliable. Consumers can store their valuable data on cloud and can use them as and when required. This leads to some key points like security of cloud data should be considered, sharing of cloud data as per requirement should be done. Allocation of required resources to the consumers should be done efficiently and above all, cloud service providers should have opportunity to gain some economical values. This research paper is based on providing some mechanism to allow file sharing among various cloud users. This paper proposed a framework that can be followed to easily share file residing on cloud with another cloud user. In this framework, concept of cryptography has been used to generate secure key that can be shared among users. Cryptography allows encryption and decryption of different normal text to some cipher text that cannot be interpreted easily. This paper has proposed secure mechanism of generating key, sharing a key and validating use of key for given file. Most important aspect considered in this research paper is, the user who owns a file and wants to provide access to other user don’t have internet access at hand. Framework uses mobile technology to contact service providers and generate a key as and when needed.

An Enhanced Digital Text passing system using SHA-512 and AES

Abstract: In the present scenario the use of images increased extremely in the cyber world so that we can easily transfer data with the help of these images in a secured way. Image steganography becomes important in this manner. Steganography and cryptography are the two techniques that are often confused with each other. The input and output of steganography looks alike, but for cryptography the output will be in an encrypted form which always draws attraction to the attacker. This paper combines both steganography and cryptography so that attacker doesn’t know about the existence of message and the message itself is encrypted to ensure more security. The textual data entered by the user is encrypted using AES algorithm. After encryption, the encrypted data is stored in the colour image by using a hash based algorithm. We have proposed a novel algorithm for mixing the AES ciphertext and the SHA-512 hash obtained from plaintext, which is embedded into an image so that the attacker cannot separate them for applying cryptanalysis.
