Furthermore, such areas do not possess vehicular traffic regulatory structures such as traffic signals, proper road lanes and traffic planning. These areas show largely unpredictable traffic pattern in means of vehicle speeds and density. This paper presents the simulation results of such scenarios in order to better understand or select the optimal performing Routing protocol among DSDV, DSR and AODV against metrics selected: Packet delivery Ratio, Packet Loss Percentage and Average End to End delay. The results show that AODV out performs DSDV and DSR in unplanned areas. To the best of our knowledge no such routing protocol performance evaluations have been performed for unplanned areas. 2017-03-20T00:00:00Z http://localhost:80/xmlui/handle/123456789/13725 Title: Analysis of FAST TCP for Multiple-Streams Implementation Authors: Awan, S.A; Arshad, M.J; Muhammad, S.S Abstract: From congestion control point of view, TCP variants are divided in two main categories, one using loss based congestion control algorithm and second, using delay based congestion control algorithm. FAST TCP is one of the TCP variants which uses delay based congestion control algorithm and it is suitable for large distance and high bandwidth delay product networks. TCP and all its variants use single byte-stream within its connection which don't adequately support request concurrency of applications that become a reason of head of line blocking. So, single streamed transport protocols have overall negative effect on application performance. In this paper the use of multistream mechanism in a single connection of FAST TCP is proposed, which provide two benefits. First is to reduce data delivery latency between transport and application layer. Second is to reduce head of line blocking. All possible issues are identified which could be faced while incorporating multistream mechanism into FAST TCP and solution of those issues are analyzed 2017-03-19T00:00:00Z http://localhost:80/xmlui/handle/123456789/13724 Title: E-Content Presentation based on Learning Styles Authors: Ahmed, M.U; Hussain, S; Bagram, M. M. M Abstract: The design and development of electronic contents has become a major area of concern in today's modern distance education system. It has opened up many opportunities, at the same time, facing challenges in a localized distant learning environment. These challenges demand to address the needs of local learners by taking into consideration their profiles and learning styles. This paper presents a model of content presentation based on learning styles. The model proposes a combination of multimedia electronic courseware tailored using visual, auditory, and kinesthetic learning style theory. Three formats of contents are proposed to fulfill the dynamic needs of learners. The dimensions of visual, auditory and kinesthetic are selected in the light of perceptual modalities. The survey module investigates the profiles and learning styles of students and learning algorithm presents the specialized contents based on their learning styles. The survey and content presentation modules are integrated with delivery tools of an open source Learning Management System. The model is implemented on a course offered at Allama Iqbal Open University, Pakistan. The result of the course offered with the supplement of specialized contents is made with the same course offered in previous semesters when traditional materials were provided to students. The test results highlight the improved performance of students using e-content as compared to the previous results. The satisfaction of students about content presentation and navigation control is also analyzed. The analysis reveals positive feedback of students about specially prepared e-contents. 2017-03-18T00:00:00Z http://localhost:80/xmlui/handle/123456789/13723 Title: Gauging Quality of Software Products Using Metrics Authors: Farid, S; Alam, M; Akbar, A; Iqbal, M.M; Siddiqui, F.A Abstract: In the current era of information technology, everyone has to deal with software products. It is crucial to gauge the quality of software products from its various aspects. Always there is need of standard and specific methods to measure any parameter in scientific manner. As quality of software is concerned, using quality metrics is a standard method which can be preferred over its (simpler) counterparts. This method enables to estimate various characteristics of a software system like cost, complexity, volume, size, function points, quality etc. these characteristics determines the quality. The aim of this study is to enhance the quality of the software developed in localized environment by getting these metrics implemented on different software products developed by the students' final year projects. Students has been divided into two groups. Conventional and controlled groups. The controlled group is bounded to follow the quality metrics during each phase of Software Development Life Cycle (SDLC) with expected quality enhancement. Results obtained by experimentation show that implementation of software quality metrics improves the quality of software product. Therefore, it is highly recommended to use the appropriate software quality metrics during all phases of SDLC. 2017-03-17T00:00:00Z
