Retransmission is not … …Journal of Computer Science, Vol. 8, Issue 11 · 6 Nov 2012 · 6,582 accessesView PDFCite
Research ArticleOpen accessIn the abstractEfficient Multipath Routing and Wavelength Allocation Using Traffic Grooming in Optical Wavelength Division Multiplexing Mesh NetworksV. Rajamani, T. KavithaIn optical WDM mesh networks, traffic grooming is essential in order to utilize the bandwidth efficiently to minimize the cost and meet the user service requirement. By grooming traffic, it is possible to reduce the total cost of all Add drop multiplexer needed. Also for the high processing capability in a WDM network, the path should be capable of carrying … …Journal of Computer Science, Vol. 8, Issue 11 · 19 Sep 2012 · 6,522 accessesView PDFCite
Research ArticleOpen accessIn the abstractHigh Performance Computing on Fast Lock Delay Locked Loop with Low Power State and Simultanoeus Switching Noise ReductionT. S. Karthik, V. Jawahar Senthil KumarProblem statement: In any multimedia processor, controller may consume most of the on-chip memory resources. The memory requirement is directly depends on algorithm shared by different blocks, so leads to failure in the system models. Approach: This study presents the implementation of DLL unit used for memory optimization. Various aspects of the underlying coarse lock detector are explored and modifications … …Journal of Computer Science, Vol. 8, Issue 3 · 6 Jan 2012 · 7,172 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Secure Routing Protocol to Eliminate Integrity, Authentication and Sleep Deprivation Based Threats in Mobile Ad hoc NetworkEdna Elizabeth Nallathambi, Radha Sankararajan, Vaithiyanathan Sundaram, Gracelin SheebaProblem statement: Network security in Mobile Ad hoc Network (MANET) is a major issue. Some of the attacks such as modification, impersonation, Time To Live (TTL) and sleep deprivation are due to misbehaviour of malicious nodes, which disrupts the transmission. Some of the existing security protocols such as ARAN, SAODV and SEAD are basically used to detect and eliminate one … …Journal of Computer Science, Vol. 7, Issue 6 · 14 Jun 2011 · 6,817 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Effective Contention Aware Stable Path Finding Approach to Provide Quality of Service in Mobile Ad hoc NetworksD. S. Thenmozhi, M. RajaramProblem statement: The application of Mobile Ad hoc NETworks (MANETs) has been increasing every day. Most applications that attract interest for use in current wired networks (e.g. video conferencing, on line movies and camera enabled instant messenger) would attract interest for MANETs also. Many applications that use MANETs include multimedia data that require Quality of Service (QoS) support for effective … …Journal of Computer Science, Vol. 7, Issue 3 · 7 Mar 2011 · 6,740 accessesView PDFCite
Research ArticleOpen accessIn the abstractAdvanced Information Technology of Slot-Switching Network Schemes for on All-Optical Variable-Length PacketSoung Yue Liew, Edward Sek Khin Wong, Choong Kwai FattProblem Statement: The purpose of this paper was to investigate all optical packet switching, because it was the key to the success of the future Internet. It can meet the stringent bandwidth requirement of future Internet applications, such as real-time video streaming.
