Research ArticleOpen accessIn the abstractEnergy Constrained Secure Hierarchical Data Aggregation in Wireless Sensor NetworksV. Bhoopathy, R. M.S. ParvathiProblem statement: Wireless sensor networks, brings out variety of different challenges at energy level, integrity, authentication, communication cost. Approach: In the secure data aggregation techniques, reduction in the energy consumption was not elaborated in detail, since aggregator means of connection to sink was either direct or through other aggregators which need high energy level. Results: We suggest an Energy Constrained … …American Journal of Applied Sciences, Vol. 9, Issue 6 · 16 Mar 2012 · 7,382 accessesView PDFCite
Research ArticleOpen accessIn the abstractA New Strategy for Signaling Overhead Reduction in the Proxy Mobile IPv6 ProtocolAdnan J. Jabir, S. Shamala, Z. ZuriatiProblem statement: The rapid growth of the Internet usage has been realized by the Mobile IPv6 (MIPv6). Concurrent to these technological advances is the communication overheads. Proxy Mobile IPv6 (PMIPv6) has been standardized to overcome the long handoff latency, packet loss and signaling overhead of MIPv6 and to exempt the mobile node from any involvement in the handoff process. Although … …American Journal of Applied Sciences, Vol. 9, Issue 4 · 13 Feb 2012 · 7,507 accessesView PDFCite
Research ArticleOpen accessIn the abstractDesign of Transmitter for CDM Based 2×2 Multiple Input Multiple Output Channel Sounder for Multipath Delay MeasurementM. Habib Ullah, M. T. Islam, Mandeep Sing et al.Problem statement: Multiple Input Multiple Output (MIMO) wireless communication system is an innovative solution to improve the bandwidth efficiency by exploiting multipath-richness of the propagation environment. The degree of multipath-richness of the channel will determine the capacity gain attainable by MIMO deployment. Approach: Therefore, it is very important to have accurate knowledge of the propagation environment/radio channel before MIMO implement. … …American Journal of Applied Sciences, Vol. 9, Issue 1 · 24 Nov 2011 · 7,903 accessesView PDFCite

Research ArticleOpen accessIn the abstractA Challenge for Routing Algorithms in Optical Multistage Interconnection NetworksMehrnaz Moudi, Mohamed OthmanProblem statement: A class of dynamic interconnection networks is Multistage Interconnection Networks (MINs) that connects input devices to output devices through a number of switch stages. MINs have assumed importance in recent years; because of their cost-effectiveness. Optical MINs are one type of MINs that have large transmission capacity in the communication networks. There is a major problem in Optical … …Journal of Computer Science, Vol. 7, Issue 11 · 29 Aug 2011 · 7,858 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Disruption-Tolerant Model for Building a Mobile Application Using Web ServiceMaryati Mohd. Yusof, Mansor Omar, Zarina ShukurProblem statement: The emerging technology in broadband telecommunication and mobile devices has increased the use of mobile applications. However, the use of mobile application is affected with low bandwidth or disrupted broadband telecommunication due to building blockage or out of coverage area. Approach: We proposed a Disruption-Tolerant Mobile Application Model (DTMA) that enables remote data access and overcomes constraint due … …Journal of Computer Science, Vol. 6, Issue 12 · 1 Dec 2010 · 7,224 accessesView PDFCite
Research ArticleOpen accessIn the abstractRecognition of Hand Printed Characters Based on Simple Geometric FeaturesSami M. Halawani, Ibrahim A. AlbidewiProblem statement: The use of computers in information processing technology nowadays is one of the main trends of office automation.
