Research ArticleOpen accessIn the abstractENERGY EFFICIENT NETWORK SELECTION USING 802.16G BASED GSM TECHNOLOGYH. Anandakumar, K. UmamaheswariHandover is the mechanism that transfers information from one terminal to another as a user moves through the coverage area of a cellular system. Here the Network selection is the handover decision process between various network environments. This handover decision will be either mobile or network initiated. In 2G GSM handover decision method especially concentrates on Received frequency signals (RFS). … …Journal of Computer Science, Vol. 10, Issue 5 · 31 Dec 2013 · 7,076 accessesView PDFCite
Research ArticleOpen accessIn the abstractMultiple-Input Multiple-Output Transmission Over a Multipath Faded ChannelsI.A.Z. QatawnehThe use of multiple antennas at the transmitter as well as at the receiver can greatly improve the capacity of a wireless link when operating in a rich scattering environment. In such an arrangement all transmitting antennas radiate in the same frequency band so the overall spectral efficiency becomes very high. Such a multiple antenna scheme, popularly known as Multiple … …American Journal of Applied Sciences, Vol. 10, Issue 3 · 11 Mar 2013 · 6,417 accessesView PDFCite

Research ArticleOpen accessIn the abstractLink Stability and Node Energy Conscious Local Route-Repair Scheme for Mobile Ad Hoc NetworksAnuradha Banerjee, Paramartha DuttaProblem statement: A mobile ad hoc network is a self-configuring network of mobile nodes connected by wireless links. As the nodes are free to move randomly, topology of the network may change rapidly and unpredictably. As a result, intermediate nodes in the communication routes tend to lose connection with each other during the communication process. In order to repair a … …American Journal of Applied Sciences, Vol. 7, Issue 8 · 31 Aug 2010 · 6,856 accessesView PDFCite

Research ArticleOpen accessIn the abstractA Flexible and Reliable Architecture for Mobile Agent SecurityGhossoon M.W. Al-SaadoonProblem statement: Wireless application protocol is a protocol that makes it possible to surf the Internet from a cellular phone or other handheld wireless. Many of us that surf the Internet from home with a 56 kbps modem think that it is slow and a cell phone only uses 9.6 kbps so WAP has to take the lesser bandwidth into … …Journal of Computer Science, Vol. 5, Issue 4 · 30 Apr 2009 · 7,324 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
