Research ArticleOpen accessIn the abstractAverage Mutual Information Analysis of Multiple Input and Multiple Output System with Multihop Relaying in Wireless Communication SystemC. Poongodi, A. ShanmugamProblem statement: Multiple Input and Multiple Output (MIMO) system with Multihop relaying techhnique is significant and active areas of wireless communication. In a rich scattering environment MIMO antenna system provides better channel capacity and data rates than single antenna systems. To provide high throughput, reliable transmission and broad coverage, wireless relaying techniques are essential in a variety of applications. In … …American Journal of Applied Sciences, Vol. 9, Issue 10 · 25 Aug 2012 · 7,556 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Optimized Ad Hoc on Demand Distance Vector Routing Protocol for Wireless NetworksV. Ponniyin Selvan, S. Senthil KumarProblem statement: Wireless Mesh Networks (WMN) is communication network made up of mesh routers and mesh clients, with mesh routers forming the backbone of the network. The WMN can be accessed by other networks through gateways and bridging functions in the mesh routers. The mesh clients can either be static or mobile with an option of forming a client mesh … …Journal of Computer Science, Vol. 8, Issue 7 · 21 Jun 2012 · 7,168 accessesView PDFCite
Research ArticleOpen accessIn the abstractAdaptable Service Component Interface Framework in Pervasive ComputingR. Vasanthi, R. S.D. WahidabanuProblem statement: Pervasive computing refers to visionary new ways of applying Information and Communication Technologies (ICT) to our daily lives. Interoperability among pervasive networked systems, in particular accounting for the heterogeneity of protocols from the application down to the middleware layer, which is mandatory for today's and even more for tomorrow's open and highly heterogeneous networks. Approach: The high demand … …Journal of Computer Science, Vol. 8, Issue 6 · 15 Mar 2012 · 6,976 accessesView PDFCite

AlliProblem statement: Healthcare is recognized various leading edge technologies and new scientific discoveries to enable better cures for diseases and better means to enable early detection of most life threatening diseases. The modern health care focused for optimally reducing the healthcare costs. Approach: The modern healthcare system enables medical professionals to remotely perform real-time monitoring, early diagnosis and treatment for … …American Journal of Applied Sciences, Vol. 9, Issue 1 · 5 Nov 2011 · 7,914 accessesView PDFCite
Research ArticleOpen accessIn the abstractCache Management for Concurrent Transaction Execution in Mobile Wireless EnvironmentJ.C. Miraclin Joyce Pamila, K. ThanushkodiProblem statement: Improvement in mobile communication technology and increased capability of mobile devices has made transaction processing possible with mobile devices. Transactions access services provided by the data server connected to the packet data network. Direct data access may overload the network and server. Data items are cached to improve data availability. The cache should be managed and maintained effectively … …Journal of Computer Science, Vol. 7, Issue 3 · 7 Mar 2011 · 6,812 accessesView PDFCite
Research ArticleOpen accessIn the abstractMobility Management for Seamless Information Flow in a Heterogeneous NetworksAdiline Macriga, AnandhakumarProblem statement: In the heterogeneous networks, generally the entire networks operating on the Radio Frequencies under wireless mode available for communication are brought under a single head based on their common operating procedures and functions. As a common mode the basic functions of the networks are requesting, tracing, sending, acknowledging, authenticating, authorizing, receiving, updating, forwarding, controlling, registering, managing. As the … …Journal of Computer Science, Vol. 7, Issue 2 · 25 Feb 2011 · 6,891 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.
