Research ArticleOpen accessEvery word in the titleAdhoc on Demand Multipath Reliable and Energy Aware Quality of Service Routing for Mobile Adhoc NetworksV. Thilagavathe, K. DuraiswamyProblem statement: In a mobile adhoc network, there are a number of challenges for providing quality of service routing for multimedia applications and real time applications like voice transmission. The QoS parameters considered in this study are link reliability and energy consumption. Existing studies estimate the link reliability constraint between two nodes using exponentially distributed epoch lengths. The major problem … …Journal of Computer Science, Vol. 8, Issue 2 · 7 Nov 2011 · 7,842 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleAn Analysis of Power Aware Congestion Control Multipath Multicast Protocol for Mobile Ad hoc NetworkDuraiswamy Karuppaswamy, Vijayaragavan ShanmugamProblem statement: In MANETs, wireless link transmission errors, mobility and congestion are major causes for packet loss. Mobility may cause packet loss in different ways. Whereas congestion in a network occurs, whenever the demands exceed the maximum capacity of a communication link especially when multiple hosts try to access a shared media simultaneously. Approach: In this study, we proposed a … …Journal of Computer Science, Vol. 6, Issue 12 · 2 Nov 2010 · 7,038 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleMultiple-Input Multiple-Output Transmission Over a Multipath Faded ChannelsI.A.Z. QatawnehThe use of multiple antennas at the transmitter as well as at the receiver can greatly improve the capacity of a wireless link when operating in a rich scattering environment. In such an arrangement all transmitting antennas radiate in the same frequency band so the overall spectral efficiency becomes very high. Such a multiple antenna scheme, popularly known as Multiple … …American Journal of Applied Sciences, Vol. 10, Issue 3 · 11 Mar 2013 · 6,417 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEfficient 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 keywordsCertain Contributions in Traffic Engineering Based on Software-Defined Networking TechnologyAs'ad Mahmoud As'ad AlnaserThe paper addresses the traffic engineering in Software-Defined Networks (SDN). A brief analysis of the features of the SDN organization, which allows to increase the Traffic Engineering (TE) efficiency, is given. The viability of using multipath routing with TE is substantiated. Taking into account the features of the SDN technology, a modified TE method, which allows to reduce the time … …Journal of Computer Science, Vol. 15, Issue 7 · 9 Jul 2019 · 7,704 accessesView PDFCite
Research ArticleOpen accessIn the keywordsAn Efficient Course Resolution Multiple-Receiver Approach for Reception of Slow Fading Signals in Digital Wireless Communication SystemsAshraf Mamdouh Aziz, Senior Member, IEEE et al.Multiple-receiver digital wireless communication systems employ several receivers and a digital central receiver with data fusion to reduce the effect of multipath fading problems. The multiple receiver observations are processed at individual receivers and sent to a digital central receiver. The digital central receiver fuses all the individual receiver data to form global data on which symbol was transmitted. In … …American Journal of Applied Sciences, Vol. 12, Issue 8 · 7 Sep 2015 · 6,509 accessesView PDFCite
Research ArticleOpen accessIn the keywordsPERFORMANCE ANALYSIS OF RANDOMIZED REVERSE AD HOC ON DEMAND DISTANCE VECTOR ROUTING PROTOCOL IN MANETK. Santhi, B. ParvathavarthiniIn high mobility, routing in Mobile Ad-Hoc Network is a very difficult task. In AODV and RAODV, all the data packets are travel through the same shortest path so the intruders can easily trace out the data path. The main objective of Randomized RAODV provides the multipath and then the paths are selected randomly for security purposes. Using randomized routing … …Journal of Computer Science, Vol. 10, Issue 9 · 30 Apr 2014 · 6,809 accessesView PDFCite
Research ArticleOpen accessIn the keywordsIMPROVING THE PERFORMANCE AND REDUCING BIT ERROR RATE ON WIRELESS DEEP FADING ENVIRONMENT RECEIVERSK. Jayanthi, V. P. Arunachalam, C. VasanthanayakiOne of the major challenges in wireless communication system is increasing complexity and reducing performance in detecting the received digital information in indoor and outdoor Environments. Consequently to overcome this problem we analyze the delay performance of a multiuser with perfect channel state information transmitting data on deep fading environment. In this proposed system, the Wireless Deep Fading Environment (WDFE) … …Journal of Computer Science, Vol. 10, Issue 3 · 29 Nov 2013 · 7,100 accessesView PDFCite
