Mobile banking adoption: A literature review

2015

Electronic commerce (e-commerce) continues to have a profound impact on the global business environment, but technologies and applications also have begun to focus more on mobile computing, the wireless Web, and mobile commerce. Against this backdrop, mobile banking (m-banking) has emerged as an important distribution channel, with considerable research devoted to its adoption. However, this research stream has lacked a clear roadmap or agenda. Therefore, the present article analyzes and synthesizes existing studies of m-banking adoption and maps the major theories that researchers have used to predict consumer intentions to adopt it. The findings indicate that the m-banking adoption litera…

Modelling Mobile Encounter Networks

2006

This article presents mobile encounter networks, which emerge when mobile devices come across each other and form a temporary connection between them using a common short-range radio technology. Local information exchanges between mobile devices results in a broadcast diffusion of information to other users of the network with a delay. In addition to presenting the concept of mobile encounter networks, we also provide an abstract method for describing the information diffusion process inside them. peerReviewed

Improving the performance of CAR systems based on mobile phones

2013

Collaborative Augmented Reality (CAR) systems allow multiple users to share a real work environment including computer-generated images in real time. Currently, the hardware features of most mobile phones makes them a natural platform for CAR systems. However, the wide variety of these hardware features can have important effects on the performance of the mobile CAR applications. This thesis proposes a performance characterization and improvement of CAR systems based on mobile phones. The research results, at the time of writing this paper, shows that a CAR system using mobile phones as clients and with a single server can support up to one thousand clients while providing interactive respo…

Mobile Search - Social Network Search Using Mobile Devices Demonstration

2008

Mobile search prototype demonstrates the possibilities of social network search in N800 mobile devices. Search is initiated from a N800 mobile device to search the contacts in mobile device's addressbook. The contacts can be other N800 mobile devices running mobile Web server or normal Web servers in the Internet with Drupal content management system. Mobile device users can select which of their personal information such as phone numbers, calendar data etc. to share via a mobile Web server. The proposed search mechanism has many benefits compared to centralized Web search engines like Google. The search can locate information which is not referenced anywhere and thus allows hidden or rare …

Mobile Encounter Networks and Their Applications

2008

This article presents mobile encounter networks (MENs), which emerge when mobile devices come across each other and form a temporary connection between them using a common short-range radio technology. Local information exchanges between mobile devices results in a broadcast diffusion of information to other users of the network with a delay. Gasoline price comparison system (GPCS), which delivers newest gasoline prices to mobile users using mobile encounter information diffusion, is described as well as other application areas where MENs could be used. The feasibility of building MENs using bluetooth is tested with the BlueCheese mobile encounter network middleware and it is found that the…

Streaming for vehicular users via elastic proxy buffer management

2004

In this article we refer to the market of vehicular networks, where groups of customers located in the same public vehicle (e.g., a train or bus) connect to a terrestrial network through a wireless/satellite backbone link. Elastic buffering is a proxy management technique devised to decouple the multimedia information retrieval rate on the network backbone from the playout streaming rate at the user terminal. It has been shown in the past that the application of elastic buffering mechanisms in terrestrial networks brings significant advantages in terms of network effectiveness. We show that elastic buffering is an extremely effective means to reduce, or even eliminate, streaming service out…

An efficient Chinese remainder theorem based node capture resilience scheme for Mobile WSNs

2010

Node capture attack is a critical issue in Mobile WSNs where attacker-controlled replicas may act maliciously. In this paper, we present a novel Chinese remainder theorem based node capture resilience scheme that can be utilized to discover and revoke captured nodes. Moreover, our scheme can limit the ability of captured nodes to further compromise forward security, backward security, and launch collusion attacks. Detailed analysis shows that our scheme indeed achieves the expected design goals.

Information Exchange in Mobile Encounter Network

2007

In this paper we analyze an information exchange method based on information diffusion in mobile encounter networks, a form of mobile peer-to-peer networks. We utilize dual mobility model which provides support for more realistic simulations compared to mobility models based only one method of movement. The distribution of the mobile device encounter intervals are discussed and analyzed via simulation runs. The logistic model is suggested to provide reasonably accurate estimates of the information diffusion process.

MCMIPv6: Multicast Configuration-based Mobile IPv6 protocol

2010

International audience; Mobile IPv6 (MIPv6) and its basic extension for network mobility NEMO were initially designed to manage the mobility of device users and networks respectively while maintaining a permanent IP address. Nevertheless, the different MIPv6's experiments have shown many lacks in case of high mobility of nodes such as in vehicular networks. To overcome these lacks, many solutions have been proposed by the research community. The most famous ones are HMIPv6 and FMIPv6 tackling each a specific issue. On the one hand, FMIPv6 introduces a solution to effectively minimize the L2/L3 latency and avoid the packets losses during the handover procedure. On the other hand, HMIPv6 is e…
