Research ArticleOpen accessIn the author namesEnhancing Indian Language Speech Recognition Systems with Language-Independent Phonetic Script: An Experimental ExplorationJose Stephan, Muthayyan Kamalam JayakumarIndia has a distinct linguistic profile that makes it extremely challenging to train Automatic Speech Recognition (ASR) systems correctly because most Indian languages have limited training material and are generally low-resource in nature. However, due to their similarity in phonemes, these languages offer an opportunity to create a single speech recognition technology. This study proposes an optimized phonetic script which … …Journal of Computer Science, Vol. 21, Issue 5 · 9 May 2025 · 6,536 accessesView PDFCite
Research ArticleOpen accessIn the author namesProcessing Large Volume of Biometric Data in the Hadoop Single Cluster Node EnvironmentJayakumar Vaithiyashankar, Shohel Sayeed, Anang Muhammad AminIn big data evolution, the analysis of large scale data and scrutinizing the required vital information becomes very demanding task. The emerging cloud platform promises and gives hope in handling the enormous volume of data. Hence, a new kind of methodology is required to tap the full potential of leveraging the big data analytics over the biometric data. In this … …American Journal of Applied Sciences, Vol. 14, Issue 12 · 27 Oct 2017 · 8,521 accessesView PDFCite
Research ArticleOpen accessIn the author namesSECURE COMMUNICATION PROTOCOL FOR PROTECTING COMPUTATION RESULT OF FREE ROAMING MOBILE AGENTG. Geetha, C. JayakumarMobile agent plays an important role in developing applications of open, distributed and mixed environments, such as the internet. Mobile agent or mobile software agent is piece of software that can operate autonomously to accomplish user assigned task. To explain more, mobile agent is the process which can migrate to hosts autonomously. As an agent travels to do execution in … …Journal of Computer Science, Vol. 10, Issue 7 · 19 Feb 2014 · 6,800 accessesView PDFCite
Research ArticleOpen accessIn the author namesPro-Active Prevention of Clone Node Attacks in Wireless Sensor NetworksK. M. Anandkumar, C. JayakumarProblem statement: Wireless mobile sensor networks are deploying large, self-organized and adaptable sets of sensors for many applications such as military, environmental, health care, remote monitoring and other applications. Unfortunately, the simplicity and low-cost of these sensors make eases cloning of compromised nodes by attackers in the network. Due to the unattended nature of wireless sensor networks, an adversary can … …Journal of Computer Science, Vol. 8, Issue 10 · 28 Aug 2012 · 7,072 accessesView PDFCite
Research ArticleOpen accessIn the author namesA Novel Page Ranking Algorithm for a Personalized Web SearchJ. Jayanthi, K. S. JayakumarProblem statement: Information on the web is growing exponentially. Today, traditional search engines provide results mainly based on the user’s query. Though the context of the query varies, the returned result seems to be same for all users. Accordingly users are expected to search for the relevant results, which is an added overhead to the users. Approach: We propose a … …Journal of Computer Science, Vol. 8, Issue 7 · 12 May 2012 · 6,995 accessesView PDFCite
Research ArticleOpen accessIn the author namesPerformance Comparison of Two On-demand Routing Protocols for Ad-hoc Networks based on Random Way Point Mobility ModelGeetha Jayakumar, G. GopinathAd hoc networks are characterized by multihop wireless connectivity, frequently changing network topology and the need for efficient dynamic routing protocols plays an important role. We compare the performance of two prominent on-demand routing protocols for mobile ad hoc networks: Dynamic Source Routing (DSR), Ad Hoc On-demand distance Vector Routing (AODV). A detailed simulation model with MAC and physical layer … …American Journal of Applied Sciences, Vol. 5, Issue 6 · 30 Jun 2008 · 7,692 accessesView PDFCite
Research ArticleOpen accessIn the author namesAd Hoc Mobile Wireless Networks Routing Protocols - A ReviewGeetha Jayakumar, G. GopinathMobile ad hoc networks(MANET) represent complex distributed systems that comprise wireless mobile nodes that can freely and dynamically self organize into arbitrary and temporary ad-hoc network topologies, allowing people and devices to seamlessly internet work in areas with no preexisting communication infrastructure e.g., disaster recovery environments. An ad-hoc network is not a new one, having been around in various forms … …Journal of Computer Science, Vol. 3, Issue 8 · 31 Aug 2007 · 115,241 accessesView PDFCite
Research ArticleOpen accessIn the author namesA Guaranteed Time and Rate Control Method for Improving QoS in WLANA. Anitha, J. JayakumariWireless Local Area Network is a mobile network, which connects the users in a small specific area. The devices within the area connect with each other through the wireless access points. The main requirements for the connection between the wireless devices are the time and the power.

Research ArticleOpen accessIn the author namesPriority Based Congestion Detection and Avoidance in Wireless Sensor NetworksR. Beulah Jayakumari, V. Jawahar SenthilkumarThe primary objective of event driven wireless sensor networks is to route the detected or monitored data at the earliest to the base station depending on their degree of priority since the data generated in a sensor network has different importance. In order to avoid indiscriminate dropping of data during congestion we propose a novel congestion protocol named priority based … …Journal of Computer Science, Vol. 9, Issue 3 · 26 Apr 2013 · 6,732 accessesView PDFCite
