Wireless communication is blooming along with Internet access from mobile devices which is an essential criterion for information access from anywhere, any time and any device. In this survey, review on various technologies like pervasive computing, mobile communication systems, selective dissemination of information, with location and device independent information interchange specification li...

As digital technologies penetrate humans’ daily lives, the possibilities for interaction and mobility have increased strongly. One of the most successful ways of leveraging mobile data input is by using 2D-barcodes (mobile tags) that can be instantly read by a mobile device with camera, like QRcodes or Datamatrix. These codes can encrypt several kinds of data, like URLs, SMS, vCard address, etc...

Mobile Ad-Hoc Network (MANET) is a dynamic, multi-hop and autonomous network composed of light wireless mobile nodes. Multicast has great importance in MANET due to their inherent broadcast capability. However, due to the dynamic topology of MANETs to build optimal multicast trees and maintaining group membership a lot many control messages required. These overhead consume the mobile node resou...

Mobile information systems are often distinguished as traditional information systems with additional support for mobile devices. This idea is based on the mostly used cellular network architecture. Mobile units have to be wirelessly connected via a base station to a server integrated in a fixed network if their users want to use the capabilities of the information system which are provided by ...

Mobile phones and stethoscopes used in neonatology units could be colonized by potentiel bacteria pathogens. It can be a vector of severe nosocomial infections and multi-drug-resistant pathogens. The aim of this study is to evaluate the microbial contamination of mobile phones and stethoscopes, used by medical and paramedical staff. The study was conducted in neonatal intensive care unit (NICU)...

The role of contingency learning was examined in 3-month-old infants’ reaching movements. Infants in the experimental group experienced 9 min of active training during which they could move their arms in a reach-like fashion to pull and move a mobile. Infants in the control group experienced 9 min of passive training during which they watched a mobile move. Prior to (pre-training) and following...

Next-generation wireless networks will provide different wireless radio access technologies(RAT) like WiFi, WiMAX and GSM to mobile user. It provide seamless mobility with high speed connectivity. Like for phone calls user preffered UMTS and WiFi hotspot for web browsing. To enable connectivity during handoff, all the available networks need to known by mobile user. When multiple access network...

In recent years, the demand for mobile commerce has increased. Due to this increased demand, mobile devices usage in internet auctions has also increased. In this paper, we propose a reverse sealed-bid auction model using collaborative mobile agents (MoRSAS) which can be used on mobile-based environment. We also proposed a new auction protocol using ECC (Elliptic Curve Cryptosystem) based signc...
