Research ArticleOpen accessIn the abstractPecan Weevil Recognition Using Support Vector Machine MethodGhulam Mubashar Hassan, Saleh Mufleh Al-SaqerProblem statement: The Pecan weevil was considered as the most dangerous pest of Pecan fruits. The aim of this research is to evaluate Support Vector Machine method (SVM) for identifying Pecan Weevil among other insects. Eventually, this recognition system will serve in a wireless imaging network for monitoring Pecan Weevils. Approach: SVM has been evaluated using two different kernel functions … …American Journal of Agricultural and Biological Sciences, Vol. 6, Issue 4 · 24 Dec 2011 · 7,927 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Comparative Performance Analysis of Multiple-Input Multiple-Output using MATLAB with Zero Forcing and Minimum Mean Square Error EqualizersBara'u Gafai Najashi, Tan XiaohengProblem statement: Multiple-Input Multiple-Output systems (MIMO) were regarded as one of the most promising technologies in field of wireless communication. Generally considered as one of the several forms of smart antenna technology, it offers considerable increase in data throughput and link range without additional bandwidth or transmit power. The general idea involves the use of several antennas at the transmitter … …American Journal of Engineering and Applied Sciences, Vol. 4, Issue 3 · 29 Nov 2011 · 8,303 accessesView PDFCite
Research ArticleOpen accessIn the abstractDesign of Transmitter for CDM Based 2×2 Multiple Input Multiple Output Channel Sounder for Multipath Delay MeasurementM. Habib Ullah, M. T. Islam, Mandeep Sing et al.Problem statement: Multiple Input Multiple Output (MIMO) wireless communication system is an innovative solution to improve the bandwidth efficiency by exploiting multipath-richness of the propagation environment. The degree of multipath-richness of the channel will determine the capacity gain attainable by MIMO deployment. Approach: Therefore, it is very important to have accurate knowledge of the propagation environment/radio channel before MIMO implement. … …American Journal of Applied Sciences, Vol. 9, Issue 1 · 24 Nov 2011 · 7,903 accessesView PDFCite
Research ArticleOpen accessIn the abstractA New Cooperative Algorithm Based on PSO and K-Means for Data ClusteringMehdi Neshat, Shima Farshchian Yazdi, Daneyal Yazdani, Mehdi SargolzaeiProblem statement: Data clustering has been applied in multiple fields such as machine learning, data mining, wireless sensor networks and pattern recognition. One of the most famous clustering approaches is K-means which effectively has been used in many clustering problems, but this algorithm has some drawbacks such as local optimal convergence and sensitivity to initial points. Approach: Particle Swarm Optimization … …Journal of Computer Science, Vol. 8, Issue 2 · 19 Nov 2011 · 7,975 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Efficient Hand-off Mechanism for Vehicular NetworksM. Dinakaran, P. BalasubramanieProblem statement: In recent times, wireless networks have become ubiquitous and the hotspot research arena. When a mobile node switches from one access network to another network, the node is said to perform a handoff. This transition is a complex and time-consuming task since after transit the mobile node has to obtain a new Care of Address (CoA) from the … …Journal of Computer Science, Vol. 8, Issue 1 · 3 Nov 2011 · 7,294 accessesView PDFCite
Research ArticleOpen accessIn the abstractErgodic Capacity Analysis of Multiple Input Multiple Output Systems with Dual Hop Amplify and Forward Relay NetworksC. Poongodi, A. ShanmugamProblem Statement: In MIMO system, capacity mainly depends on the channel and the antenna characteristics. The capacity can be improved by proper design of antenna elements and choosing appropriate array configuration and the directive elements give more capacity than omni directional elements. The dual polarized antennas are better than single polarized antennas as the former can provide two information channels. … …Journal of Computer Science, Vol. 7, Issue 12 · 17 Oct 2011 · 6,745 accessesView PDFCite
Research ArticleOpen accessIn the abstractArtificial Neural Networks Based Red Palm Weevil (Rynchophorus Ferrugineous, Olivier) Recognition SystemSaleh Mufleh Al-Saqer, Ghulam Mubashar HassanProblem statement: The most dangerous insect for the existence of palm trees in entire world is Red Palm Weevil (scientifically named as Rynchophorus Ferrugineous, Oliveir). The proposed research is conducted to develop an identification system for Automated Wireless Red Palm Weevil Detection and exterminated. The core idea of the proposed research is to develop software that can utilize image processing … …American Journal of Agricultural and Biological Sciences, Vol. 6, Issue 3 · 4 Aug 2011 · 9,190 accessesView PDFCite
Research ArticleOpen accessIn the abstractMobile Node Speed Detection Mechanism in Hierarchical Mobile Internet Protocol (IPv6)Zulkeflee Kusin, Mohamad Shanudin ZakariaProblem statement: IETF has introduced Hierarchical Mobile IPv6 (HMIPv6) to support mobility problem in the next generation Internet Protocol (IPv6). The key concept behind this protocol is the usage of Mobility Anchor Point (MAP) located at any level router of network to support hierarchical mobility management and seamless handover. The distance MAP selection in HMIPv6 causes MAP overloaded as the … …Journal of Computer Science, Vol. 7, Issue 9 · 27 Jul 2011 · 6,621 accessesView PDFCite
Research ArticleOpen accessIn the abstractNovel Mechanism Control Algorithm for Wired NetworkV. B. Kirubanand, S. PalaniammalProblem statement: A critical issue in wireless network where the data can hack by the person and we add a novel encryption mechanism to protect the data transfer from client to server and vice versa. Approach: We present a queuing model of a client and server that uses for bulk arrival service. The arrival of data requests is assumed to … …Journal of Computer Science, Vol. 7, Issue 9 · 27 Jul 2011 · 6,654 accessesView PDFCite
Research ArticleOpen accessIn the abstractKoch Curves: Rewriting System, Geometry and ApplicationMamta Rani, Riaz Ul Haq, Norrozila SulaimanProblem statement: Recently, new Koch curves have been generated by dividing the initiator into three unequal parts.
