Research ArticleOpen accessIn the abstractREDUCING TRANSMITTED POWER OF MOVING RELAY NODE IN LONG-TERM EVOLUTION-ADVANCED CELLULAR NETWORKSJaafar A. Aldhaibani, A. Yahya, R. B. Ahmad et al.Wireless multi-hop relay networks have become very significant technologies in mobile communications. These networks ensure data rate transfer and coverage extension with a low cost. In this study two types of relay are studied; Fixed Relay Node (FRN) and Moving Relay Node (MRN). Where system analyses for uplink and downlink transmission are derived in this study. Moreover the optimal relay … …Journal of Computer Science, Vol. 10, Issue 6 · 3 Feb 2014 · 6,737 accessesView PDF Cite

Research ArticleOpen accessIn the abstractParticle Swarm Optimization-Based Routing Protocol for Clustered Heterogeneous Sensor Networks with Mobile SinkR. Sudarmani, K.R. Shankar KumarIn Wireless Sensor Networks (WSN) sensor nodes with sensing, computing and communication infrastructure are randomly deployed and organized as clusters. Most of the existing sensor networks focus on homogeneous in which the cluster heads are changed periodically. To improve the lifetime of energy constraint battery powered WSN and to avoid energy sink-hole problem; Clustered Heterogeneous Sensor Networks (HSN) are analyzed … …American Journal of Applied Sciences, Vol. 10, Issue 3 · 18 Mar 2013 · 6,840 accessesView PDF Cite

Research ArticleOpen accessIn the abstractPath Loss Prediction Using Fuzzy Inference System and Ellipsoidal RulesMario Versaci, Salvatore Calcagno, Fabio La Foresta, Biagio CammarotoIt is well known as the prediction of radio wave path loss in urban environment plays a key role in order to correctly plan wireless systems and mobile communication networks. To obtain more flexible prediction models able to give accurate results, in recent years Soft computing Techniques has been exploited. In this study, a novel approach based on ellipsoidal fuzzy … …American Journal of Applied Sciences, Vol. 9, Issue 12 · 6 Dec 2012 · 6,770 accessesView PDF Cite

Research ArticleOpen accessIn the abstractPerformance Evaluation of Multicrypt Encryption MechanismRhymend Uthariaraj Vaidyanathan, Lydia Elizabeth Benjamin, John Prakash ArockiasamyMulticast communication allows a single message packet to be routed to multiple nodes simultaneously. Membership in a multicast group is dynamic, allowing nodes to enter and leave the multicast session. Besides the benefits, multicast communication presents the challenge of securing the communication. In order to preserve confidentiality the general encryption mechanism used for point to point communications are used. A … …American Journal of Applied Sciences, Vol. 9, Issue 11 · 4 Sep 2012 · 7,168 accessesView PDF Cite

Research ArticleOpen accessIn the abstractMulti-Threshold based Scheduling for Multi-User Multiple-Input Multiple-Output SystemsK. Chanthirasekaran, M. A. BhagyaveniProblem statement: Multi-User Multi-Input Multi-Output (MU-MIMO) system had eventually used in 4th generation wireless networks either to achieved diversity gain or multiplexing gain. Many recent scheduling addresses the threshold based resource allocation where in resource were not utilized properly. Approach: In this study a new Multi Threshold Based Channel Aware Scheduling (MTCAS) was proposed for performance improvement and proper resource … …Journal of Computer Science, Vol. 8, Issue 7 · 21 Jun 2012 · 6,938 accessesView PDF Cite
