Research ArticleOpen accessIn the abstractA Practical Design of Anti-Theft Car Protection System Based on MicrocontrollerMohammed Abuzalata, Muntaser Momani, Sayel Fayyad, Suleiman Abu-EinProblem statement: This study presents a new design for an anti-theft protection System as an inexpensive solution to protect cars from theft and from non-authorized users by using microcontroller-based system. Approach: Three stages of protection to strengthen the security of the car: Firstly, when the user access the car by the car key and entered the wrong password, the power … …American Journal of Applied Sciences, Vol. 9, Issue 5 · 5 Mar 2012 · 8,410 accessesView PDFCite
Research ArticleOpen accessIn the abstractAdaptive Multi-Path Routing for Load Balancing in Mobile Ad Hoc NetworksS. Soundararajan, R. S. BhuvaneswaranProblem statement: Load balancing and network congestion are the major problems in Mobile Ad-hoc Networks (MANET) routing. Most of the existing routing protocols provide solutions to load balancing or congestion or fault-tolerance, individually. Approach: We propose congestion controlled adaptive multi-path routing protocol to achieve load balancing and avoid congestion in MANETs. The algorithm for finding multi-path routes computes fail-safe multiple … …Journal of Computer Science, Vol. 8, Issue 5 · 18 Feb 2012 · 7,451 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Analysis and Overview of Wireless Routing ProtocolsN. Dhanalakshmi, P. AlliProblem statement: In the past, the main focus of the research in the wireless network is to provide optimal routes between source and destination nodes. The wireless routing is required additional computational effort than wired routing in order to fulfill the major wireless characteristics such as battery power constraints, frequent mobility and less processing. Approach: In addition to wired routing … …Journal of Computer Science, Vol. 8, Issue 3 · 17 Jan 2012 · 7,637 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Optimal Path Management Strategy in Mobile Ad Hoc Network Using Fuzzy and Rough Set TheoryP. Seethalakshmi, M. Joseph Auxilius Jude, G. RajendranProblem statement: Mobile Ad Hoc Network (MANET) is a collection of wireless mobile nodes that dynamically forms a network. Most of the existing ad-hoc routing algorithms select the shortest path using various resources. However the selected path may not consider all the network parameters and this would result in link instability in the network. The problems with existing methods are … …American Journal of Applied Sciences, Vol. 8, Issue 12 · 15 Oct 2011 · 7,671 accessesView PDFCite
Research ArticleOpen accessIn the abstractCoverage Eligibility Rule based Coverage Maintenance Protocol for Energy Conservation in Wireless Sensor NetworksA. Balamurugan, T. PurushothamanProblem statement: Wireless Sensor Networks (WSNs) comprise of small nodes with sensing, computation and wireless communication capabilities. Nodes in a sensor network are severely constrained by energy and computing power. Continuous working of sensor nodes leads to quick depletion of battery power and reduces the overall lifetime. To prolong the lifetime of the sensor nodes, efficient routing protocol that could … …Journal of Computer Science, Vol. 7, Issue 10 · 6 Aug 2011 · 6,634 accessesView PDFCite
Research ArticleOpen accessIn the abstractEnergy Aware Multiple Constraints Quality of Service Routing Protocol with Dynamic Mobility Prediction for Mobile Ad hoc NetworksSenthilkumar Maruthamuthu, Somasundaram SankaralingamProblem statement: This study presents a source based reactive protocol called "Energy Aware Multiple Constraints QoS Routing Protocol with Dynamic Mobility Prediction (EMQRPDM)" for MANET. It is an enhanced version of our previous protocol called "Power aware multiple QoS constraints routing protocol with mobility prediction (PMQRPMP)". It addresses the issues such as routing, mobility and power management in MANET. Approach: … …Journal of Computer Science, Vol. 7, Issue 6 · 14 Jun 2011 · 6,482 accessesView PDFCite
Research ArticleOpen accessIn the abstractMisbehaving Node Detection in Mobile Ad Hoc Networks using Multi Hop Acknowledgement SchemeUsha Sakthivel, S. RadhaProblem statement: For any node in a Mobile Ad hoc Network conservation of battery power and bandwidth are the priority. Hence, they try to reduce the overload they would otherwise incur when they forward packets. This selfish behavior of a node affects the throughput of the network. The nodes may also choose a back off value of shorter duration. These … …Journal of Computer Science, Vol. 7, Issue 5 · 7 May 2011 · 6,714 accessesView PDFCite
Research ArticleOpen accessIn the abstractMobile Element Scheduling for Efficient Data Collection in Wireless Sensor Networks: A SurveyK. Indra Gandhi, P. NarayanasamyProblem statement: Wireless Sensor Networks (WSN) has become a very interesting field of research and has been deployed for various applications. The data sensed by the sensors need to be transmitted over to a Base Station (BS) where the data processing is done. Approach: The existing systems generally employ Multi-hop routing for data aggregation at the BS, where several nodes … …Journal of Computer Science, Vol. 7, Issue 1 · 15 Jan 2011 · 7,296 accessesView PDFCite
Research ArticleOpen accessIn the abstractNew Control Technique Applied in Dynamic Voltage Restorer for Voltage Sag MitigationRosli Omar, Nasrudin Abd Rahim, Marizan SulaimanThe Dynamic Voltage Restorer (DVR) was a power electronics device that was able to compensate voltage sags on critical loads dynamically. The DVR consists of VSC, injection transformers, passive filters and energy storage (lead acid battery). By injecting an appropriate voltage, the DVR restores a voltage waveform and ensures constant load voltage. There were so many types of the control … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 1 · 31 Mar 2010 · 8,141 accessesView PDFCite
Research ArticleOpen accessIn the abstractOptimal Power Multicast Problem in Wireless Mesh Networks by Using a Hybrid Particle Swarm OptimizationAllam Maalla, Chen Wei, Haitham J. TahaProblem statement: Most mobile nodes in a wireless ad hoc network are powered by energy limited batteries; the limited battery lifetime imposes a constraint on the network performance. Therefore, power consumption of network operations is critical and subject to optimization. Approach: A novel hybrid PSO was proposed for solving the minimum power multicast problem in wireless ad-hoc networks.
