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. Due to the lack of optical Random Access Memory (RAM), however, the all-optical schemes studied in the literature … …Journal of Computer Science, Vol. 6, Issue 1 · 31 Jan 2010 · 7,189 accessesView PDFCite
Research ArticleOpen accessIn the abstractThroughput-Delay Trade-Off for Slotted Aloha Multiple Access with Capture EffectA. Chehri, P. Fortier, P. M. TardifProblem statement: Medium Access Control (MAC) protocols are one of most important research issues in communication and networking. There have been proposed several MAC protocols in wireless as well in wired networks. Approach: ALOHA-based protocol is the simplest one, being able to provide prompt access, reliable channels and support for quality of service. However its limited capacity, low throughput and … …Journal of Computer Science, Vol. 5, Issue 9 · 30 Sep 2009 · 6,922 accessesView PDFCite
Research ArticleOpen accessIn the abstractReducing Broadcast Overhead Using Clustering Based Broadcast Mechanism in Mobile Ad Hoc NetworkN. Karthikeyan, V. Palanisamy, K. DuraiswamyProblem statement: Network wide broadcasting is an important function in Mobile Ad Hoc Networks (MANET), which attempts to deliver packets from a source node to all other nodes in the network. Broadcasting is often very useful for route discovery, naming, addressing and helping multicast operations in all kinds of networks. For designing broadcast protocols for ad hoc networks, one of … …Journal of Computer Science, Vol. 5, Issue 8 · 31 Aug 2009 · 7,034 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Discrete Event Modeling and Simulation of Wave Division Multiplexing Unidirectional Slotted Ring Metropolitan Area NetworkH. A. Fua’ad, S. Shamala, M. Othman, Z. ZuriatiProblem statement: The lack of uniformity in the choice of simulation platforms for optical WDM networks stands behind the difficulty of developing a common simulation environment. Correlating WDM unidirectional slotted ring network to Discrete Event Simulation (DES) encompassing event definition, time advancing mechanism and scheduler has yet to be developed. Approach: The study focused on the proposed and the development … …Journal of Computer Science, Vol. 5, Issue 6 · 30 Jun 2009 · 6,685 accessesView PDFCite
Research ArticleOpen accessIn the abstractThree Dimensional Multidirectional Geographical IP Traceback: Direction Ratio Sampling AlgorithmA. Rajiv Kannan, K. Duraiswamy, K. SangeethaProblem statement: An important and challenging problem is that of tracing DOS/DDOS attack source. IP traceback is the process of identifying the actual source(s) of attack packets, So that the attackers can be held accountable as also in mitigating them, either by isolating the attack sources or by filtering packets for away from the victim. Several IP traceback schemes have … …Journal of Computer Science, Vol. 5, Issue 2 · 28 Feb 2009 · 7,238 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Channel Adaptive Energy Efficient and Fair Scheduling Media Access Control Protocol for Mobile AdHoc NetworksP. Priakanth, P. ThangarajProblem statement: A major drawback in the existing protocols in dealing with energy management issues is that the time varying nature of the wireless channels among the ad hoc nodes is ignored. Approach: This study proposed a channel adaptive energy efficient Medium Access Control (MAC) protocol, for efficient packets scheduling and queuing in an ad hoc network, with time varying … …Journal of Computer Science, Vol. 5, Issue 1 · 31 Jan 2009 · 7,557 accessesView PDFCite
Research ArticleOpen accessIn the abstractVirtual Mobility to Improve Cooperation in Mobile Ad hoc NetworksA. Baaziz, S. PierreWe study the impact of mobility on the level of cooperation between mobile nodes in a mobile ad hoc network. In a mobile ad hoc network, if the nodes are static or have a reduced mobility and if some nodes adopt a selfish behaviour, the performance of the network is affected. This is because the same nodes that are relaying … …Journal of Computer Science, Vol. 4, Issue 12 · 31 Dec 2008 · 6,961 accessesView PDFCite
Research ArticleOpen accessIn the abstractProvisioning QoS in Virtual Private Network using Dynamic SchedulingR. Ravi, S. RadhakrishnanActive and programmable networks change the functionality of routers and switches by using VPN endpoints and active packets. The authors present a new packet scheduling scheme called active scheduling to control and maintain QoS parameters in virtual private networks (VPNs) within the confines of adaptive and programmable networks. In active scheduling a VPN endpoint on the router monitors the accumulated … …Journal of Computer Science, Vol. 4, Issue 1 · 31 Jan 2008 · 6,735 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Novel Packet Marketing Method in DDoS Attack DetectionChanghyun Beak, Junaid Ahsenali Chaudhry, Keonsoo Lee et al.Functionality and availability are one of the main characteristics of internet and hence very inviting for attackers to try to provoke a denial-of-service attack. As the intensity and frequency of DDoS attacks has increased, various preventive mechanisms have also been proposed. One of the most effective defence mechanisms proposed was Path Identification (Pi). This method tracks the packet transmission path. … …American Journal of Applied Sciences, Vol. 4, Issue 10 · 31 Oct 2007 · 7,078 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Comparative Study between Various Protocols of MANET NetworksMohammed F. Al-Hunaity, Salam A. Najim, Ibrahiem M. El-EmaryMulticast Ad-Hoc on-Demand Distance Vector (MAODV) protocol keeps sending control packets within static periods whether there was sending of data packets or not, and it was not concerned with the amount of these data packets. Based on this, many people found out that there are a high number of control packets in the short-lived connection. The main idea of this … …American Journal of Applied Sciences, Vol. 4, Issue 9 · 30 Sep 2007 · 6,960 accessesView PDFCite
