Research ArticleOpen accessIn the abstractPerformance Improvement and Deadlock Prevention for a Distributed Fault Diagnosis AlgorithmThabit S. MohammedThis research presents an overview to the issue of fault diagnosis in distributed systems and an evaluation study to some of the algorithms proposed in literature for performing distributed fault diagnosis. One algorithm was chosen and adopted for implementation in a simulator for investigation. A strategy for improving the performance of this algorithm and preventing deadlock was proposed in this … …Journal of Computer Science, Vol. 3, Issue 2 · 28 Feb 2007 · 6,913 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordIoT-Fog based Smart-Building Security System Design and Performance EvaluationMaha Medhat, Khaled El-Shafey, Ali RashedThis paper aims to develop a smart building-security system utilizing fog technology. Fog computing is an innovative solution to reduce latency and network congestion, in which the cloud is extended to the edge of the network. The proposed system can detect an intruder, fire and water leakage. It is implemented using Raspberry Pi, Arduino, Pi-camera and different sensors. The sensors … …Journal of Computer Science, Vol. 16, Issue 9 · 3 Oct 2020 · 7,212 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordCombining Q-Learning and Multi-Layer Perceptron Models on Wireless Channel Quality PredictionAndrea L. Piroddi, Maurizio TorregianiOne of the most complex challenges that wireless communication systems will face in the coming years is the management of the radio resource. In the next years, the growth of mobile devices, forecast (CISCO, 2020), will lead to the coexistence of about 8.8 billion mobile devices with a growing trend for the following years. This scenario makes the reuse of … …American Journal of Engineering and Applied Sciences, Vol. 14, Issue 1 · 10 Mar 2021 · 6,766 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordDynamic Bandwidth Allocation for Multiple Traffic Classes in IEEE 802.16e WiMax Networks: A Petrinet ApproachS. Geetha, R. JayaparvathyProblem statement: WiMAX supports multiple types of traffic such as data, voice and video. Each flow requires a certain minimum bandwidth to achieve its QoS. Bandwidth allocation to traffic classes should be in such a way that fairness criteria is met with. Hence, we propose a dynamic bandwidth allocation mechanism to achieve fair and efficient allocation. Approach: We present a … …Journal of Computer Science, Vol. 7, Issue 11 · 6 Sep 2011 · 7,105 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordPerformance Study of Threshold Variations in Temporal Decision Systems for Routing in Vehicular Ad hoc NetworksB. S. Shylaja, V. Mary Anita Rajam, V. Uma Maheswari, Arul SiromoneyProblem statement: Route maintenance and re-discovery are expensive in signaling and computation for routing in Vehicular Ad hoc Networks (VANETs). Hence it was desirable to choose the optimal route during the route selection phase. Approach: In this study, the threshold-based routing protocol β-wt uses the notion of threshold from variable precision rough sets. This protocol was used to evaluate routing … …Journal of Computer Science, Vol. 6, Issue 12 · 9 Nov 2010 · 6,893 accessesView PDF Cite
