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 PDF Cite

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. To … …Journal of Computer Science, Vol. 8, Issue 4 · 27 Jan 2012 · 7,716 accessesView PDF Cite

Research ArticleOpen accessIn the abstractTraffic Flow Analysis Model based Routing Protocol For Multi-Protocol Label Switching NetworkE. R. Naganathan, S. Rajagopalan, P. Herbert RajProblem statement: Multi-Protocol Label Switching (MPLS) is a mechanism which is used in high-performance telecommunications networks that directs and carries data from one network node to the next with the help of labels. Traffic management is still an issue in MPLS network as it involves high speed internet. Approach: This study proposed a traffic flow analysis of the real time … …Journal of Computer Science, Vol. 7, Issue 11 · 25 Aug 2011 · 6,743 accessesView PDF Cite

Research ArticleOpen accessIn the abstractEffects of Adhesive on Coupling Efficiency of Planar Light Waveguide PackagingYang Bo, Duan Ji-anProblem statement: Advanced optoelectronic devices are a kind of key and basic components for next generation communication, untouched sensor, medical testing. They have lots of advantages including greater communication performance, larger capacity, and more fixable form. But light coupling and package structure seriously affects performance of optoelectronic devices. So a lot of attaching methods were proposed to package optoelectronic devices. … …Current Research in Nanotechnology, Vol. 1, Issue 2 · 21 Jun 2011 · 7,140 accessesView PDF Cite

Research ArticleOpen accessIn the abstractEvaluation of the Impact of Obstacles on the Capacity of a LTE Network in Urban Area in the UplinkAkohoule Alex, Konate Adama, Brou Pacôme, Asseu OlivierPower control is a major issue in the deployment of 4G mobile networks. Indeed, environmental constraints (relief, Air, noise,...) affect the propagation channels of mobile network systems. The new multimedia services, which consume large amounts of radio resources (frequencies), then lead to an optimization of power control in the cellular coverage in the uplink direction. The aim is to optimize … …American Journal of Engineering and Applied Sciences, Vol. 12, Issue 1 · 17 Jan 2019 · 8,295 accessesView PDF Cite

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 PDF Cite

Research ArticleOpen accessIn the abstractThe Euro: Future Prospects and Consideration for Non-Euro CountriesFarhad Ghannadian, Irina PenovskaProblem statement: Many more Central and Eastern European Countries (CEEC) have decided to adopt the euro. Given the attraction and uncertainties associated with moving into a common currency, the potential gains and losses of a currency adoption was of academic and political interest. The economic impact of implementing a common currency was examined by studying the before and after of … …American Journal of Economics and Business Administration, Vol. 3, Issue 2 · 7 Apr 2011 · 6,899 accessesView PDF Cite
