Research ArticleOpen accessIn the keywordsA Vision-Based Approach to Real-Time Trust Evaluation within Multiagent SystemsAlan Kruger, Sun YiAs robotic autonomy increases, single-agent systems are evolving into more complex multiagent systems that require more factors for successful implementation. In exchange for this complexity, applications such as autonomous delivery services and reconnaissance swarms become possible when they are infeasible with only one agent. By incorporating Trust into the multiagent system, the complexity of the agent-to-agent relationships can be managed … …Journal of Mechatronics and Robotics, Vol. 9, Issue 1 · 21 Mar 2025 · 7,937 accessesView PDFCite
Research ArticleOpen accessIn the keywordsEvaluation of Multiple Input Multiple Output (MIMO) System Capacity with Spatial CorrelationsT. Gunasekaran, K. R. Shankar KumarProblem statement: Today’s wireless technologies just won’t get us to the hyper connectivity of uninterrupted access from any mobile device with unlimited bandwidth at real-time speeds. This is due to the low data throughput and scarcity in spectrum. Approach: Under the condition of uncorrelated antenna elements, capacity of the Multiple Input Multiple Output (MIMO) system can be increased linearly with … …Journal of Computer Science, Vol. 7, Issue 10 · 4 Aug 2011 · 8,108 accessesView PDFCite
Research ArticleOpen accessIn the keywordsBluetooth Wireless Network Authentication Using Radio Frequency Communication ProtocolGhossoon M. Waleed, M. Faizal, R. B. Ahmad et al.Problem statement: Bluetooth has emerged as very popular ad hoc network standard today. Bluetooth network applications include wireless synchronization, e-mail/internet/intranet access using local personal computer connections, hidden computing through automated applications and networking. Due to this ability, it is not impossible for the network to receive any attack. Approach: In this study, we developed an algorithm to build new software … …Journal of Computer Science, Vol. 5, Issue 9 · 30 Sep 2009 · 7,819 accessesView PDFCite
Research ArticleOpen accessIn the keywordsA Novel Routing Protocol with High Energy Performance in Mobile Special NetworksAli Norouzi, B. Berk UstundagProblem statement: Mobile Special Networks do not have a predetermined structure. This type of networks can dynamically reorganize network connection relationships due to change of neighborhoods and the relative positions. Approach: There are many problems in creation of a special network such as routing, wireless media, energy consumption and transportability. Results: Although these networks primarily had been formed for small … …Journal of Computer Science, Vol. 7, Issue 1 · 15 Jan 2011 · 7,304 accessesView PDFCite
Research ArticleOpen accessIn the keywordsCache Management for Concurrent Transaction Execution in Mobile Wireless EnvironmentJ.C. Miraclin Joyce Pamila, K. ThanushkodiProblem statement: Improvement in mobile communication technology and increased capability of mobile devices has made transaction processing possible with mobile devices. Transactions access services provided by the data server connected to the packet data network. Direct data access may overload the network and server. Data items are cached to improve data availability. The cache should be managed and maintained effectively … …Journal of Computer Science, Vol. 7, Issue 3 · 7 Mar 2011 · 6,809 accessesView PDFCite
Research ArticleOpen accessIn the keywordsDesign and Cost Performance of Decoding Technique for Hybrid Subcarrier Spectral Amplitude Coding-Optical Code Division Multiple Access SystemR.K.Z. Sahbudin, M.K. Abdullah, M. Mokhtar et al.Problem statement: A hybrid technique combining subcarrier multiplexed and Spectral Amplitude Coding-Optical Code Division Multiple Access (SAC-OCDMA) deploying the Khazani-Syed code was proposed. It was proposed as a mean of increasing the maximum number of simultaneous active users by increasing the subcarrier and/or the SAC-OCDMA code word. Multiple Access Interference (MAI) is the most dominant cause of performance degradation in … …Journal of Computer Science, Vol. 7, Issue 10 · 4 Aug 2011 · 6,875 accessesView PDFCite
Research ArticleOpen accessIn the keywordsDesign and Implementation of Medical Information Systems For Managing and Following up Work Flaw in Hospitals and ClinicsHassan Mohammed M. ElmetwalyProblem statement: This research study deals with the problem of maintaining data, deemed to be one of the biggest problems of health entities. Most hospitals and clinic suffer loss of data saved in this databases and unavailability of strong cohesive information systems. Approach: Our need for such databases and information systems motivates us to seek solutions and technologies that might … …Journal of Computer Science, Vol. 7, Issue 1 · 16 Dec 2010 · 8,816 accessesView PDFCite
Research ArticleOpen accessIn the keywordsV-Band Fade Dynamics Characteristics Analysis in Tropical RegionKhairayu Badron, Ahmad Fadzil Ismail, Jafri Din, Ahmad Tharek Abdul RahmanProblem statement: Satellite operations at V-band in tropical and equatorial regions are constrained as a result of attenuation from rain. Approach: Statistics for 20 consecutive months of V-band terrestrial link signal attenuation measurements in Malaysia were presented in this analysis. Such information was considered very pertinent for Earth-space communication link design and can be used for initial groundwork plan for … …American Journal of Applied Sciences, Vol. 7, Issue 8 · 31 Aug 2010 · 7,802 accessesView PDFCite
