Research ArticleOpen accessAll words, across the recordPerformance Evaluation of Implementing Calls Prioritization with Different Queuing Disciplines in Mobile Wireless NetworksSalman A. AlQahtani, Nasser-Eddine RikliIt is known that efficient call handling mechanisms can greatly improve cellular network performance. One way to improve system performance of cellular network is to use efficient handover schemes when users changes between cells. This paper focuses on the performance evaluation of originating and handover calls prioritization using different queue size and discipline. Both calls will be queued until they … …Journal of Computer Science, Vol. 2, Issue 5 · 31 May 2006 · 6,470 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordDESIGN AND IMPLEMENTATION OF GLOBAL POSITIONING SYSTEM RECEIVER IN FIELD PROGRAMMABLE GATE ARRAY WITH SHORT MESSAGE SERVICEGovindaraju Kavya, Vittal Thulasi BaiIn recent years, survival rate from myocardial infarction and bundle branch block has been increased due to the advancements in medical field. Continuous monitoring and location management of these patients becomes an essential task. Hence this study aims in design and development of GPS in a Field Programmable Gate Array (FPGA) and interfaced with a GSM modem to transmit the … …Journal of Computer Science, Vol. 10, Issue 1 · 12 Nov 2013 · 7,563 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordA Static Analysis of Android Source Code for Lifecycle Development Usage PatternsNoura Hoshieah, Samer Zein, Norsaremah Salleh, John GrundyBuilding robust Android apps is a non-trivial task that requires skilled developers to understand various Android platform peculiarities. However, among the Android developers community, a large fractions are considered to be novice and inexperienced developers. One of the main peculiarities in the Android app development is the activity lifecycle model. A developer needs to have deep understanding of the different … …Journal of Computer Science, Vol. 15, Issue 1 · 10 Jan 2019 · 8,661 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordFast Iterative Frequential Equalization, Application to Mobile CommunicationsM. T. Taba, S. Femmam, M. BeddaThe Space Time Adaptive Processing (STAP) is a promising approach in the improvement of the wireless communication systems. Since it makes possible to reduce interferences ISI (Inter Symbol Interference) and CCI (Co-Channel Interference) but its disadvantage is the intensive treatment which reduces the speed of convergence of the algorithm LMS (Least Mean Square) and SMI (Sampling Matrix Inversion). Our approach … …American Journal of Applied Sciences, Vol. 3, Issue 11 · 30 Nov 2006 · 6,813 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordIndirect Kalman Filter in Mobile Robot ApplicationSurachai PanichProblem statement: The most successful applications of Kalman filtering are to linearize about some nominal trajectory in state space that does not depend on the measurement data. The resulting filter is usually referred to as simply a linearized Kalman filter. Approach: This study introduced mainly indirect Kalman filter to estimate robot’s position. A developed differential encoder system integrated accelerometer is … …Journal of Mathematics and Statistics, Vol. 6, Issue 3 · 30 Sep 2010 · 7,385 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordTwo Factor Authentication for e-Government Services using Hardware-Like One Time Password GeneratorsGiuseppe Della Penna, Pietro Frasca, Benedetto IntrigilaA safe and accessible authentication technique is a prerequisite for any modern e-government application. Two-factor authentication is currently widely adopted, since it alleviates many vulnerabilities of password-based authentication. The majority of e-government systems currently make use of text messages to deliver the second authentication factor, but these messages do not constitute an adequate (secure and reliable) solution. In this paper … …Journal of Computer Science, Vol. 15, Issue 1 · 26 Jan 2019 · 8,167 accessesView PDFCite
Review ArticleOpen accessAll words, across the recordGeneration Test-Cases of Attacks in Mobile Ad Hoc NetworkSara Chadli, Mohammed Saber, Abdelhak ZiyyatThe number and increasing complexity of attacks against MANETs have grown significantly in recent years. While many security proposals have been developed. However, these proposals suffer from the problems of tests and evaluations. Among these solutions, the Intrusion Detection Systems (IDS) that can act as defense mechanisms. However, this last poses serious problems for its evaluators that need classify the … …Journal of Computer Science, Vol. 12, Issue 10 · 14 Dec 2016 · 6,522 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordTRUSTWORTHY ENABLED RELIABLE COMMUNICATION ARCHITECTURE IN MOBILE AD HOC NETWORKSaravanan Dhavamani, Chandarasekaran Ramasamy, M. G. Sharavana KumarAd hoc networks are widely used in military and other scientific area. There are various kind of routing protocols are available to establish the route, with the proper analyzation one can choose the routing protocol to form their own network with respect to number of nodes and security considerations. The mobility of nodes makes the environment infrastructure less. It also … …Journal of Computer Science, Vol. 10, Issue 7 · 12 Feb 2014 · 6,995 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordSECURITY IN VEHICULAR AD HOC NETWORK BASED ON INTRUSION DETECTION SYSTEMOmkar Pattnaik, Binod Kumar PattanayakImplementation of mobile ad hoc networks has eventually captured practically most of the parts of day-to-day life. One variation of such networks represents the Vehicular Ad Hoc Networks (VANETs), widely implemented in order to control day-to-day road traffic. The major concern of VANETs is oriented around providing security to moving vehicles that makes it possible to reduce accidents and traffic … …American Journal of Applied Sciences, Vol. 11, Issue 2 · 27 Dec 2013 · 7,022 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordSSM: Slot Scheduling Mechanisms in a Multihop Wireless Hotspot NetworkMaan Younis AbdullahOur focus was to determine a "slot" time for message forwarding. To this end, we model the system as a "Queue" where the time for packet forwarding is determined by slot, at different slot range for each relaying node. We also introduced one important reason of the poor performance is the close coupling between medium contention and network congestion. Our … …Journal of Computer Science, Vol. 3, Issue 7 · 31 Jul 2007 · 6,445 accessesView PDFCite
