Research ArticleOpen accessAll words, across the recordEnhanced RSACRT for Energy Efficient Authentication to Wireless Sensor Networks SecurityP. Kalyani, C. ChellappanProblem statement: The Security in WSN has become a challenge because of its inherent limitations of resources imposed on the sensor nodes. Authentication and key management scheme allows WSNs to be used with confidence and maintains integrity of data in sensor networks. Approach: In the WSN limited resource scenario the generation of public key done and are randomly pre distributed … …American Journal of Applied Sciences, Vol. 9, Issue 10 · 18 Aug 2012 · 7,339 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordICT based Sustainable Rural Business Opportunities in Developing Countries: A Wireless-Networked RCP-RAP ApproachMd. Abdur Rahman, Mohammad Upal Mahfuz, Kazi M. Ahmed, R. M.A.P. RajathevaInformation and Communication Technology (ICT) is gaining much research attention in present times especially for its ability towards poverty alleviation. In this study the prospect of rural business opportunities in developing countries more specifically in the target country, Bangladesh, has been investigated from the viewpoint of wirelessly networked Rural Communication Point (RCP) approach. It is proposed that if only one … …American Journal of Applied Sciences, Vol. 2, Issue 8 · 31 Aug 2005 · 7,080 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordCongestion Free Routing in Adhoc NetworksT. Senthil Kumaran, V. SankaranarayananProblem statement: A Mobile Ad-Hoc Network (MANET) is a temporary network; the mobile devices in an ad-hoc network are communicating through wireless links without any pre-existing infrastructure. The one major problem of this network is network congestion, it may take place at any intermediate nodes when data packets are traveling from source to destination. The major problems of congestion or … …Journal of Computer Science, Vol. 8, Issue 6 · 4 Apr 2012 · 7,236 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordDensity Based Routing Algorithm for Spare/Dense Topologies in Wireless Mobile Ad-Hoc NetworksEssam Natsheh, Khalid BuraggaProblem statement: A Mobile Ad-Hoc Networks (MANETs) operate in environments without infrastructures with an undefined network size. Most routing protocols of Mobile Ad-hoc Networks (MANETs) were studied using open space models where nodes were able to move throughput the entire simulation area. However, a more realistic topology should account for restricted mobility of nodes, such as in an urban city … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 2 · 30 Jun 2010 · 7,461 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordBluetooth Wireless Monitoring, Managing and Control for Inter Vehicle in Vehicular Ad-Hoc NetworksHelia Mamdouhi, Sabira Khatun, Javad ZarrinProblem statement: The car users expect more and more accessories available in their cars, but the accessories available needed manage by driver manually and not properly manage by smart system. All these accessories are able to control by user manually using different and standalone controllers. Besides, the controller itself uses RF technology which is not existed in mobile devices.
