Proposal of Enhanced FDD Process Model
Статья научная
Feature driven development (FDD) is an agile process model that develops software according to the client features. The FDD consists of five processes, several practices and both are providing benefits to improve the software development. Although the FDD provides lots of benefits, but still endures many flaws. In previous research, there have been made numerous modifications in FDD with different aspects. These modifications could not fix all type of flaws and FDD requires improvements in many aspects. These flaws reduce the agility to deliver increments continuously and make an inverse relationship between quality and agility. Due to this relationship, the FDD does not utilize enough time on making extensive documentation, robust design, client or user involvement, and efficient testing. To overcome these issues, an enhanced feature driven development model is proposed. EFDD introduces best practice of agile manifesto named as behavioral driven development used in FDD. In this way, the focus on delivering increments quickly is achieved without affecting the quality of the software. The proposed model provides maximum agility with continuous delivery according to client features and efficient testing strategy which have asses every feature according to client specified functionality.

Proposal to Improve Mobility in Service Oriented Architecture
Статья научная
Service Oriented Architecture (SOA) is a standard to implement and design applications. It is a channel of communication between service consumer (SC) and service provider (SP). SP offers a service and SC uses a service. Mobile web service verifier component, of SOA architecture, matches best service that is called. Mobile web service verifier component finds a best match of particular service in SP if it is available by the SP. Therefore, there is a pressing need to develop a component that can create a service if it is not found by mobile web service verifier component. This problem is addressed by proposing a new component for SOA architecture called service upgrade (SU) to increase and improve the service creation speed and satisfy SC and SP needs. The questionnaire is used as a research design to evaluate the proposed solution by providing qualitative data. The results show that the majority of respondents are in favor of the proposed solution. It is anticipated that the proposed solution will cater the industrial problem in hand.

Proposed risk management model to handle changing requirements
Статья научная
The change in requirements while construction of a software may bring into several risks like over budget and extra schedule. The changes in requirements are considered as a high risk to fail the software projects. A good project manager always incorporates risk management paradigm to manage the risks of changing requirements. This research uses available statistical techniques to estimate the cost of risk management with respect to the changing requirement. In addition, a hybrid cost estimation model is proposed using action strategy model to counteract, mitigate and manage the risks of changing requirements. The proposed model is validated using an industrial case study in Saudi Electricity Company (SEC) to conclude the results. The results are found supportive because the proposed model shows significant improvement to estimate the costs of changing requirements as compared to the existing cost estimation models.

Protocols for Secure Internet of Things
Статья научная
Internet of Things has become a buzzword. It refers to networking of simplest mundane objects not just for human to machine or human to human interactions but for independent thing to thing interaction as well. Such interconnected or smart environment can do wonders but at the same time poses numerous threats to human lives. The ordinary and less powerful objects from day to day life are holding sensitive and private data from humans and trying to transport that through the insecure world of Internet. This new phase of Internet or Internet of Things (IoT) is yet in its infancy and does not have a security support mechanism of its own. The Internet and World Wide Web deal with interconnection of powerful devices like computers or smart phones and are well supported by standard Internet protocols ensuring optimum security and protection. The lightweight versions of the existing Internet protocols are backing the operations of IoT to a large extent but the security needs are not met completely as of yet. Many research organizations and individual researchers are working to make existing protocols and infrastructure applicable in IoT. This paper highlights the threats posed by uncontrolled proliferation of Internet of things and discusses major protocols that have been or that are being designed to overcome the security issues raised by Internet of things.

Random Pattern Standard Bit Embedding for Minimized Histogram Difference
Статья научная
The rapid development of the transfer of data via internet made it easier to send the correct information and quicker to the destination. Today's massive demand of web applications needs the information to be communicated in a secure manner. The transmission of information in a public communication system isn't secure because of interception and improper manipulation by an eavesdropper. So for this problem, the solution is Steganography, which means the art of hiding information in ways that avert the revealing of hiding messages. Secure video steganography is a difficult task of sending the embedded data to the receiver without being detected. This paper presents a steganographic model which is based on random pattern based sequential bit encoding. The proposed model has been designed to enhance the security level. The video embedding creates the higher level of security for the embedded data. Here the encrypted secret image is embedded into the blocks of a cover video file which is selected using autocorrelation function which measures the similarity between the two images. The embedding is done on the basis of random selection of the pixels in the blocks of cover video. The performance parameters that are used to obtain results are taken in the form of chi-square histogram difference measurements. The proposed model increases the security by using random pattern embedding.

Статья научная
The traditional project driven teaching method is a popular teaching method of implementation of inquiry-based teaching model. However, students have the differences of the basic knowledge resulting in increasing the difficulty of the implementation of project-driven approach. This calls for revisiting the current project driven teaching process. The proposed teaching method of LTO (Learning, Training, Operating) by extending project-driven approach is presented to resolve the problems of traditional project driven teaching method challenging to teachers at universities. The LTO teaching approach encourages more students to participate in courses and stimulates outstanding students to have more developing room. At the same time, the students are led to closely track the up-to-date technology, inspired to research knowledge in-depth. Eventually, the new values are reflected in the area of engineering education from the closed university education to the open society one and from a single classroom to actual job positions. Finally, a case study are performed to testify the efficiency of the proposed model.

Regression Test Suite Execution Time Analysis using Statistical Techniques
Статья научная
After applying techniques such as test design generation using combinatorial approach, test case selection, test suite minimization and prioritization, further reduction in execution time of the test suite is possible. This is necessary when there is scarcity of resources and time to execute the test suites. We investigate the statistical techniques which can be employed for analysis and reduction of test execution time further. The approach can help in extrapolating the execution time of test suite when the regression team wants to augment the test suite. The statistical techniques can aid in choosing the best test setup in terms of operating system, tool and Java virtual machine combination for given test setup. Further, these techniques are not the activities that need to be carried out before every execution of the test suite. Once the best combination is chosen the same can be used unless there is change in one of the layers of test setup. The activities mentioned in the paper can be part of test setup planning and maintenance phase.
