Research ArticleOpen accessIn the abstractLIGHTWEIGHT VIGILANT PROCEDURE TO IMPLEMENT SECURITY MEASURES IN HIGHLY ROVING MILITARY OPERATIONSJ. Udhayan, Rajesh BabuThe performance of Mobile Ad hoc Network (MANET) becomes questionable in highly roving and mission critical application like military operation. Security measures like encryption, authentication, digital signature has been proposed for MANET. However all those mechanisms need some kind of static infrastructure and it is extremely difficult to implement such an infrastructure throughout the military mission. Therefore in this work, … …Journal of Computer Science, Vol. 9, Issue 10 · 18 Sep 2013 · 6,641 accessesView PDFCite

Research ArticleOpen accessIn the abstractEnergy Efficient Hidden Markov Model Based Target Tracking Mechanism in Wireless Sensor NetworksB. Amutha, M. PonnavaikkoProblem statement: Target tracking is a challenging application in Wireless Sensor Networks (WSNs) because it is computation-intensive and requires real-time location processing. This study proposes a practical target tracking system based on the Hidden Markov Model in a distributed signal processing framework. In this framework, wireless sensor nodes perform target detection and tracking, whereas target localization requires the collaborative signal … …Journal of Computer Science, Vol. 5, Issue 12 · 31 Dec 2009 · 7,174 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Indoor Positioning System (IPS) using Grid ModelWutjanun Muttitanon, Nitin Kumar Tripathi, Marc SourisTo date many positioning systems are available to determine or track a user's location; three main categories include Global Positioning System (GPS), wide area location system and indoor positioning system. GPS has its limitation (poor signals) in indoor or urban uses, while wide-area location systems are cellular networks dependent. For indoor positioning system many approaches like infrared sensing, radio frequency, … …Journal of Computer Science, Vol. 3, Issue 12 · 31 Dec 2007 · 7,175 accessesView PDFCite
