Research ArticleOpen accessIn the abstractFuzzy Based Dynamic Buffer Management in Wimax 16m NetworksD. Karunkuzhali, Dinesh Chandra TomarIn WiMAX 16m networks, buffer allocation is the major problem to be handled for offering Quality of Service (QoS). The lack of buffers increases the packet loss and queuing delay. In this study we propose a fuzzy based dynamic buffer management in WiMAX 16 m network. The Base Station (BS) estimates the parameters such as number of user requests, flow … …Journal of Computer Science, Vol. 8, Issue 12 · 8 Nov 2012 · 6,812 accessesView PDFCite
Research ArticleOpen accessIn the abstractDynamic Route Shortening and Route Repairing Mechanism for Mobile Ad Hoc NetworksS. Revathi, T. R. RangaswamyProblem statement: Ad hoc Networks are wireless networks without any fixed infrastructure. The network topology changes frequently and unpredictably due to the random movement of the nodes. The Ad Hoc on Demand Distant Vector Routing (AODV) protocol works in a dynamic fashion, by establishing a route on demand and continues that route until it breaks. Due to the changing network … …Journal of Computer Science, Vol. 8, Issue 8 · 11 Jul 2012 · 7,068 accessesView PDFCite
Research ArticleOpen accessIn the abstractCongestion Free Routing in Adhoc NetworksT. Senthil Kumaran, V. SankaranarayananProblem statement: A Mobile Ad-Hoc Network (MANET) is a temporary network; the mobile devices in an ad-hoc network are communicating through wireless links without any pre-existing infrastructure. The one major problem of this network is network congestion, it may take place at any intermediate nodes when data packets are traveling from source to destination. The major problems of congestion or … …Journal of Computer Science, Vol. 8, Issue 6 · 4 Apr 2012 · 7,236 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Multipath Energy Efficient Congestion Control Scheme for Wireless Sensor NetworkB. Chellaprabha, S. Chenthur PandianProblem statement: In most of the existing works either detection of congestion or scheme for congestion control in wireless sensor networks are presented. A very few works have been done, taken in to account of both congestion detection and congestion control. In most of the congestion detection works they have not achieved accuracy in detecting congestion and have resulted with … …Journal of Computer Science, Vol. 8, Issue 6 · 20 Mar 2012 · 6,857 accessesView PDFCite
Research ArticleOpen accessIn the abstractEfficient Broadcasting in Mobile Ad Hoc Networks Using Context Aware Adaptive Routing Protocol during Network PartitionsS. V.M.G. Bavithiraja, R. RadhakrishnanProblem statement: In mobile ado network, broadcasting is a common operation for route establishment and for sending control and emergency messages. Reliable Broadcasting in mobile ad hoc networks requires delivery of messages from different sources to all the nodes of the network within bounded time. The nodes are highly mobile and the network is highly dynamic and decentralized. Most of … …Journal of Computer Science, Vol. 8, Issue 5 · 28 Feb 2012 · 6,461 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Fault Tolerant Congestion Aware Routing Protocol for Mobile Adhoc NetworksG. Rajkumar, K. DuraiswamyProblem statement: The performance of ad hoc routing protocols will significantly degrade when there are faulty nodes in the network. Packet losses and bandwidth degradation are caused due to congestion and thus, time and energy is wasted during its recovery. The fault tolerant congestion aware routing protocol addresses these problems by exploring the network redundancy through multipath routing. Approach: In … …Journal of Computer Science, Vol. 8, Issue 5 · 23 Feb 2012 · 6,446 accessesView PDFCite
Research ArticleOpen accessIn the abstractA New Strategy for Signaling Overhead Reduction in the Proxy Mobile IPv6 ProtocolAdnan J. Jabir, S. Shamala, Z. ZuriatiProblem statement: The rapid growth of the Internet usage has been realized by the Mobile IPv6 (MIPv6). Concurrent to these technological advances is the communication overheads. Proxy Mobile IPv6 (PMIPv6) has been standardized to overcome the long handoff latency, packet loss and signaling overhead of MIPv6 and to exempt the mobile node from any involvement in the handoff process. Although … …American Journal of Applied Sciences, Vol. 9, Issue 4 · 13 Feb 2012 · 7,500 accessesView PDFCite
Research ArticleOpen accessIn the abstractMultipath Adaptive Packet Dispersion for Voice ApplicationsJ. Faritha Banu, V. RamachandranProblem statement: The quality of Voice over IP applications is decided by the main factors like network capacity and technologies such as codec type, Packet Loss Concealment (PLC) and Forward Error Correction (FEC). Approach: In MPLS networks multiple Label Switched Paths (LSP) are established between MPLS ingress and egress nodes to enhance the network performance and QoS for subscribers.

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 · 7,289 accessesView PDFCite
Research ArticleOpen accessIn the abstractHybrid Traffic Management Model for Multi-Protocol Label Switching NetworkE. R. Naganathan, S. RajagopalanProblem statement: MPLS is a highly scalable, protocol agnostic and data-carrying mechanism. Traffic engineering is the major research area in MPLS due to the emerging requirements of MPLS and the internet usage. A major objective of traffic engineering is to minimize or eliminate high-loss situations.
