Research ArticleOpen accessIn the abstractPerformance 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 · 6,890 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 · 7,206 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordSimulator for Optimization of Software Project Cost and ScheduleP. K. Suri, B. BhushanEach phase of the software design consumes some resources and hence has cost associated with it. In most of the cases cost will vary to some extent with the amount of time consumed by the design of each phase .The total cost of project, which is aggregate of the activities costs will also depends upon the project duration, can be … …Journal of Computer Science, Vol. 4, Issue 12 · 31 Dec 2008 · 7,419 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 · 7,101 accessesView PDF Cite
