Research NotesOpen accessIn the abstractA Comprehensive Study on Mobility Issues in AODVThiripurasundari SivakrishnakumarAd-hoc network plays an important role in wireless networks as they are self-configured and can be operated independently with limited resources. The critical issue is to assess the performance of routing protocols in Mobile Ad hoc Network (MANET) due to the frequent changes in network topology. Here the Ad-hoc On demand Distance Vector (AODV) routing protocol, which is quite susceptible … …Journal of Computer Science, Vol. 11, Issue 10 · 2 Jan 2016 · 6,722 accessesView PDFCite
Research ArticleOpen accessIn the abstractEVALUATING THE PERFORMANCE OF THE LOCATION-AIDED ROUTING-1P ROUTE DISCOVERY ALGORITHMAli Maqousi, Hussein Al-BahadiliDynamic Routing Protocols (DRPs) are widely-used for routing information among mobile nodes in Mobile Ad Hoc Network (MANET) and establish and maintain connectivity within the network. A DRP comprises two main phases: route discovery and route maintenance. The route discovery phase involves transmission of large number of redundant control packets consuming significant portion of the nodes power and increase communication … …Journal of Computer Science, Vol. 10, Issue 3 · 28 Nov 2013 · 6,480 accessesView PDFCite
Research ArticleOpen accessIn the abstractSTUDY AND ANALYSIS OF ROUTING PROTOCOLS IN MOBILE AD-HOC NETWORKUma Mani, Ramasamy Chandrasekaran, V. R. Sarma DhulipalaMobile Ad-hoc Networks (MANETs) is a network without a fixed Infrastructure. In wireless networks users expect to get access to the network security and to exchange information anytime and anywhere. The ad hoc wireless network consists of mobile networks which creates architecture for communication without the help of traditional fixed-position routers. Establishing strong routes and providing security are the main … …Journal of Computer Science, Vol. 9, Issue 11 · 30 Sep 2013 · 6,706 accessesView PDFCite
Research ArticleOpen accessIn the abstractReal-Time Optimal Control for Rotary Inverted PendulumViroch Sukontanakarn, Manukid ParnichkunProblem statement: The rotary inverted pendulum system was a highly nonlinear model, multivariable and absolutely unstable dynamic system. It was used for testing various design control techniques and in teaching modern control. The objectives of this study were to: (i) Develop a real rotary inverted pendulum which derived the mechanical model by using Euler-Lagrange and (ii) Design controller algorithm for … …American Journal of Applied Sciences, Vol. 6, Issue 6 · 30 Jun 2009 · 7,846 accessesView PDFCite
Research ArticleOpen accessIn the abstractSelective Flooding Based on Relevant Nearest-Neighbor using Query Feedback and Similarity across Unstructured Peer-to-Peer NetworksIskandar Ishak, Naomie SalimProblem statement: Efficient searching is a fundamental problem for unstructured peer to peer networks. Flooding requires a lot of resources in the network and thus will increase the search cost. Searching approach that utilizes minimum network resources is required to produce efficient searching in the robust and dynamic peer-to-peer network. Approach: This study addressed the need for efficient flood-based searching … …Journal of Computer Science, Vol. 5, Issue 3 · 31 Mar 2009 · 7,696 accessesView PDFCite
Research ArticleOpen accessIn the abstractNumerical Study of Airflow around Vehicle A-pillar Region and Windnoise Generation PredictionM. H. Shojaefard, K. Goudarzi, H. FotouhiFlow separation and reattachment around the vehicle A-pillar region dictates strong pressure fluctuations on the side window surfaces and can also lead to generate aerodynamic noise. The objective of this work is to investigate qualitative flow visualization of airflow behaviour around vehicle A-pillar and its potential to generate windnoise in this region. By means of Computational Fluid Dynamic (CFD) under … …American Journal of Applied Sciences, Vol. 6, Issue 2 · 28 Feb 2009 · 7,335 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Novel Approach to Modeling and Flooding in Ad-hoc Wireless NetworksO. Issaad, S. Pierre, G. I. Ivascu, O. GarciaThis study proposes a new modeling approach for wireless ad-hoc networks. The new approach is based on the construction of fuzzy neighborhoods and essentially consists of assigning a membership or importance degree to each network radio link which reflects the relative quality of this link. This approach is first used to model the flooding problem and then an algorithm is … …Journal of Computer Science, Vol. 4, Issue 12 · 31 Dec 2008 · 7,015 accessesView PDFCite

Research ArticleOpen accessAll words, across the recordTransient Stability Assessment of a Power System Using Probabilistic Neural NetworkNoor Izzri Abdul Wahab, Azah MohamedThis study presents transient stability assessment of electrical power system using Probabilistic Neural Network (PNN) and principle component analysis. Transient stability of a power system is first determined based on the generator relative rotor angles obtained from time domain simulation outputs. Simulations were carried out on the IEEE 9-bus test system considering three phase faults on the system. The data … …American Journal of Applied Sciences, Vol. 5, Issue 9 · 30 Sep 2008 · 7,027 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordSecondary User Sensing Time Optimization in Sensing-Transmission Scheduling for Dynamic Spectrum Access in Cognitive RadioInderdeep Kaur Aulakh, Renu VigThe constraint of limited frequency spectrum for wireless communication is very daunting. The radio spectrum licensed to permanent users is wasted at times when not used continuously. Cognitive radio technology involves a change in regulation of radio spectrum. In cognitive radio networks a secondary user network is designed for efficiently using gaps in spectrum and not causing at the same … …Journal of Computer Science, Vol. 11, Issue 8 · 5 Nov 2015 · 7,343 accessesView PDFCite
