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 · 6,477 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Effective Queue Management Scheme for Data CommunicationSheela Thavasi, Nityanandam NatarajanProblem statement: The growth in the needs of Internet applications that transmit massive amount of data has led to the emergence of Effective Queue Management. Approach: Queues were used to smooth spikes in incoming packet rates and to allow the router sufficient time for packet processing. When the waiting time is less a better queue management is ensured thereby resulting … …Journal of Computer Science, Vol. 7, Issue 3 · 7 Mar 2011 · 7,758 accessesView PDFCite
Research ArticleOpen accessIn the abstractColored Image Compression Using Gradient Adjustment Prediction Based WaveletMuna Faik Hanoon Al-SammraieProblem statement: Uncompressed graphics, audio and video data require considerable storage capacity and transmission bandwidth. Despite rapid progress in mass-storage density, processor speeds and digital communication system performance, demand for data storage capacity and data transmission bandwidth continues to outstrip the capabilities of available technologies. The recent growth of data intensive digital audio, image and video (multimedia) based web applications, … …Journal of Computer Science, Vol. 7, Issue 2 · 25 Feb 2011 · 7,307 accessesView PDFCite
Research ArticleOpen accessIn the abstractAlgorithm Development for Measurement and Prediction the Traffic in Broad Band Integrated Service NetworksMohammad Al Rawajbeh, Ibrahim Mansi, Majed HussienProblem statement: In this study an effort had been made to develop an algorithm for traffic prediction and measurement for a wide use networks such as B-ISDN. Such algorithm should base on valuable parameters during the various stages of data elements transmission. The offered algorithm was expected to enforce the main sources of congestion problem in network. With this technique … …Journal of Computer Science, Vol. 6, Issue 10 · 10 Aug 2010 · 7,481 accessesView PDFCite
Research ArticleOpen accessIn the abstractUnequally Error Protected Wireless Data Transmission Using Channel State Information and Adaptive EncodersYaseen H. Tahir, Chee Kyun Ng, N. K. Noordin et al.Problem statement: Higher data transmission rate with Quality of Services (QoS) guarantee is an important objective for wireless broadband communication systems. Unlike other communication system, real-time transmission requires high data rate and good error performance to ensure good quality of service. This study describes the design problem of real-time wireless data transmission which provides higher achievable data rate with Unequal … …Journal of Computer Science, Vol. 5, Issue 12 · 31 Dec 2009 · 7,250 accessesView PDFCite
Research ArticleOpen accessIn the abstractHeterogeneous GPRS-WLAN Integration Based on Ad-Hoc NetworksS. LouvrosIn heterogeneous microcellular networks like 802.11(WLAN)-GPRS, users can roam around through vertical handoffs. The major problem in heterogeneous networks is that they support different QoS requirements and the users suffer sudden changes in data rates. This study proposes certain routing algorithms to extend the service time of mobile handsets in the wireless network with higher available data rate, thus improving … …Journal of Computer Science, Vol. 4, Issue 2 · 28 Feb 2008 · 6,538 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Effective Transmission and Browsing Methodology for Streaming VideoK. K. Thyagharajan, V. RamachandranBrowsing streaming video quickly through Internet with in the available bandwidth is a challenging one and it is also time consuming. The user has to browse, view and listen to the complete video to identify relevant contents. Most of the video summarization techniques presented in research papers are suitable only for stand-alone environments. They are not addressing or analyzing the … …Journal of Computer Science, Vol. 2, Issue 4 · 30 Apr 2006 · 6,997 accessesView PDFCite
Research ArticleOpen accessIn the abstractIntroducing Song Form Intelligence into Streaming AudioKevin CurranWhen receiving streaming media over a low bandwidth wireless connection, users can experience not only packet losses but also extended service interruptions. These dropouts can last for as long as 15 sec. During this time no packets are received and if not addressed, these dropped packets cause unacceptable interruptions in the audio stream. A long dropout of this kind may … …Journal of Computer Science, Vol. 1, Issue 2 · 30 Jun 2005 · 6,572 accessesView PDFCite
Research ArticleOpen accessIn the abstractDynamic Reconfiguration of IP Domain Middleware Stacks to Support Multicast Multimedia Distribution in a Heterogeneous EnvironmentKevin Curran, Gerard ParrSeamless connectivity to multiple wireless networks independently of a fixed point is becoming increasingly important for mobile devices however wireless networks differ in bandwidth, size and access costs each requiring protocol functions to enable devices to communicate efficiently. In addition, due to the divergence of users and applications, traditional stacks are frequently enriched with additional functionality such as transport protocol … …Journal of Computer Science, Vol. 1, Issue 1 · 31 Mar 2005 · 6,781 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Fuzzy Based Mechanism For Allocation of Grid ResourcesM. Poonguzhali, S. ShanmugavelOne of the main challenges in Grid computing is efficient allocation of resources (CPU-hours, network bandwidth) to the tasks submitted by users. In our previous work a technique to allocate resources in a grid environment using predicted data has been proposed. We propose utilization of the predicted data the resources were classified into three types; they are permanent resources, semi-permanent … …Journal of Computer Science, Vol. 9, Issue 5 · 23 May 2013 · 6,772 accessesView PDFCite
