Research ArticleOpen accessIn the abstractPerformance Comparison of Active Queue Management TechniquesT. B. Reddy, A. AhammedCongestion is an important issue which researchers focus on in the Transmission Control Protocol (TCP) network environment. To keep the stability of the whole network, congestion control algorithms have been extensively studied. Queue management method employed by the routers is one of the important issues in the congestion control study. Active Queue Management (AQM) has been proposed as a router-based … …Journal of Computer Science, Vol. 4, Issue 12 · 31 Dec 2008 · 7,193 accessesView PDFCite
Research ArticleOpen accessIn the abstractDiscrete Simulation Framework for Wireless Cellular NetworksM. Al-Sanabani, S. Subramaniam, M. Othman, Z. ZukarnainThe aim of the discrete simulation framework is to deal with issues of the next generation of wireless cellular networks (e.g., multimedia traffic, radio resource management and mobility... etc) and to provide a platform for current and future investigations involving wireless cellular networks. The simulator is built from the scratch to enable customization requirements of any research and to provide … …Journal of Computer Science, Vol. 4, Issue 12 · 31 Dec 2008 · 7,070 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Novel Routing Technique against Packet Dropping Attack in Adhoc NetworksN. Bhalaji, Sinchan banerjee, A. ShanmugamProblem Statement: Mobile adhoc networks (MANETs) were extensively used in defense and rescue applications. The dynamic topology of MANETs allows nodes to join and leave the network at any point of time. This dynamic property of MANET has rendered it vulnerable to various security attacks. Many trust establishment methods were proposed to increase the security in MANET. In this paper … …Journal of Computer Science, Vol. 4, Issue 7 · 31 Jul 2008 · 6,582 accessesView PDFCite
Research ArticleOpen accessIn the abstractComparative Performance Analysis of Mobile IPv6 Protocols: Special Reference to Simultaneous BindingsShariq Haseeb, Ahmad F. IsmailMobile IP is the Internet Engineering Task Force (IETF) proposal to cater for All-Internet Protocol (All-IP) mobility. It forms the backbone for next generation Wireless Internet Technology to provide uninterrupted network service while on the move. Our paper conducts a performance study of the various Mobile Internet Protocol version 6 (IPv6) protocols such as Simple Mobile IPv6, Hierarchical Mobile IPv6, … …Journal of Computer Science, Vol. 2, Issue 2 · 28 Feb 2006 · 7,865 accessesView PDFCite
Research ArticleOpen accessIn the abstractImpact of Asymmetric Encryption Algorithms in a VANETEdward David Moreno, Leila C.M. Buarque, Florêncio Natan et al.This paper describes the impact of using asymmetric encryption algorithms, with emphasis on RSA, ECC and Multivariate Quadratic Quasigroup (MQQ) algorithms, in a scenario of Vehicular Ad hoc Network (VANET). In the research we used the simulator NS-3 with specific module for vehicular networks. The algorithms were implemented in C and were included in NS-3. The results, even in a … …Journal of Computer Science, Vol. 11, Issue 12 · 30 Jan 2016 · 6,852 accessesView PDFCite
Research ArticleOpen accessIn the abstractPERFORMANCE ANALYSIS OF ANTI-COLLISION ENABLED ROBOT USING HYBRID BEACON SCHEDULING APPROACHP. Prabakaran, M. SaravananIn multi-robot environment, when many robots are moving in the same workspace, there is a possibility of their physical collision with themselves as well as with physical objects. In this study, hybrid beacon scheduling protocol is proposed and for avoiding such collisions in robotic mobile environment with low latency and power consumption. The purpose of deploying this protocol is to … …American Journal of Applied Sciences, Vol. 11, Issue 5 · 6 Mar 2014 · 6,449 accessesView PDFCite
Research ArticleOpen accessIn the abstractCluster Based Time Division Multiple Access Scheduling Scheme for Zigbee Wireless Sensor NetworksB. Meenakshi, P. AnandhakumarIn IEEE 802.15.4 ZigBee Wireless Sensor Networks, an efficient scheduling mechanism is required for reliable data transmission. Further, concurrent transmission of huge data through CSMA/CA incurs more packet collision rate. This complicated condition has to be eliminated to improve the system throughput. In this study, we propose to deploy cluster based TDMA scheduling mechanism for IEEE 802.15.4 ZigBee Wireless Sensor … …Journal of Computer Science, Vol. 8, Issue 12 · 26 Nov 2012 · 6,682 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Impact of Radio Propagation Models on Ad Hoc Networks PerformancesA. Rhattoy, A. ZatniProblem statement: Wireless networks are characterized by a dynamic topology triggered by the nodes mobility. Thus, the wireless multi-hops connection and the channel do not have determinist behaviour such as: Interference or multiple paths. Moreover, the nodes’ invisibility makes the wireless channel difficult to detect. This wireless networks’ behaviour should be scrutinized. Approach: In our study, we mainly focus on … …Journal of Computer Science, Vol. 8, Issue 5 · 2 Mar 2012 · 6,848 accessesView PDFCite
Research ArticleOpen accessIn the abstractPerformance of Improved Directed Diffusion Protocol for Sensor Networks under Different Mobility ModelsK. E. Kannammal, T. PurusothamanProblem statement: In sensor networks, some routing protocols performance differs under different mobility models. In ns2, there are two kinds of directed diffusion protocols, rate based gradient mechanism (diffusion/rate) and probability based gradient mechanism (diffusion/prob). In this research, we proposed a method to improve the performance of Directed diffusion/prob protocol by adding a new interest message propagation mechanism and analyzed … …Journal of Computer Science, Vol. 8, Issue 5 · 25 Feb 2012 · 6,749 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Interaction between Congestion-Control Based Transport Protocols and Manet Routing ProtocolsKhuzairi Mohd Zaini, Adib M. Monzer Habbal, Fazli Azzali et al.Problem statement: Although many efforts have been done on studying the behaviour of TCP in MANET, but the behaviour of TFRC remain unclear in MANET. The purpose of this research is two folds. First, we studied the behaviour of TFRC and TCP over AODV and DSR as the underlying routing protocols in terms of throughput, delay and jitter. The second … …Journal of Computer Science, Vol. 8, Issue 4 · 28 Jan 2012 · 7,155 accessesView PDFCite
