Research ArticleOpen accessAll words, across the recordAn Evolution Framework for Evaluating Intelligent Spectrum Sensing Mechanisms in Cognitive RadioArchana Krishnamuthy, Sudhindra Kumbhashi RajgopalCognitive radio technology has advanced to address the challenge of limited spectrum availability by employing spectrum sensing techniques. This process is framed as a detection problem involving two core hypotheses: Hypo-0 and Hypo-1. Hypo-0 represents the scenario where only noise is present, and its modeling depends on parameters such as the number of observed samples, the timing of signal acquisition, … …Journal of Computer Science, Vol. 21, Issue 8 · 4 Sep 2025 · 5,807 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordA Defense Mechanism for Differential Power Analysis Attack in AESJ. Vijaya, M. RajaramIn modern wireless communication world, the security of data transfer has been the most challenging task. In embedded system, AES is the most extensively used cryptographic algorithm in practice. But its functionality has been disrupted by the DPA attack. There have been several countermeasures to tackle those attacks, but this study proposes variably a new measure to defend this DPA … …Journal of Computer Science, Vol. 11, Issue 2 · 1 Sep 2014 · 7,257 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordComparing the Impact of Black Hole and Gray Hole Attacks in Mobile Adhoc NetworksUsha, BoseMobile Adhoc Networks (MANETs) are dynamic in nature. Any nodes can join and leave the network at any time. Hence any type of intruders can attack the communication at any time, especially the routing mechanism between the nodes. In this study, we study and understand two types of attacks which cause more damage to the routing performance of MANET; the … …Journal of Computer Science, Vol. 8, Issue 11 · 7 Sep 2012 · 6,904 accessesView PDFCite

Research ArticleOpen accessAll words, across the recordREVIEW CLUSTERING MECHANISMS OF DISTRIBUTED DENIAL OF SERVICE ATTACKSWesam Bhaya, Mehdi Ebady ManaaDistributed Denial of Service attacks (DDoS) overwhelm network resources with useless or harmful packets and prevent normal users from accessing these network resources. These attacks jeopardize the confidentiality, privacy and integrity of information on the internet. Since it is very difficult to set any predefined rules to correctly identify genuine network traffic, an anomaly-based Intrusion Detection System (IDS) for network … …Journal of Computer Science, Vol. 10, Issue 10 · 26 Jun 2014 · 7,635 accessesView PDFCite
Review ArticleOpen accessAll words, across the recordCritical Review of Economical Denial of Sustainability (EDoS) Mitigation TechniquesParminder Singh Bawa, Selvakumar ManickamMany organizations and service providers have started shifting from traditional server-cluster infrastructure to cloud-based infrastructure. The threat of Distributed Denial of Service (DDoS) attack continues to wreak havoc in these cloud infrastructures. In addition to DDoS attacks, a new form of attack known as Economic Denial of Sustainability (EDoS) attack has emerged in recent years. EDoS which is unique to … …Journal of Computer Science, Vol. 11, Issue 7 · 29 Oct 2015 · 7,824 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordTrust Based Node Replication Attack Detection Protocol for Wireless Sensor NetworksV. Manjula, C. ChellappanThe harmful attack against Wireless Sensor Networks (WSN) is Node Replication attack, where one or more node(s) illegitimately claims an identity, are also called clone attack due to identity theft. The Node replication attack can be exceedingly injurious to many important functions of the sensor network such as routing, resource allocation, misbehavior detection, This study proposes a method Randomized and … …Journal of Computer Science, Vol. 8, Issue 11 · 5 Nov 2012 · 6,756 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordA Novel Packet Marketing Method in DDoS Attack DetectionChanghyun Beak, Junaid Ahsenali Chaudhry, Keonsoo Lee et al.Functionality and availability are one of the main characteristics of internet and hence very inviting for attackers to try to provoke a denial-of-service attack. As the intensity and frequency of DDoS attacks has increased, various preventive mechanisms have also been proposed. One of the most effective defence mechanisms proposed was Path Identification (Pi). This method tracks the packet transmission path. … …American Journal of Applied Sciences, Vol. 4, Issue 10 · 31 Oct 2007 · 7,076 accessesView PDFCite
