mobile ad hoc networks (manet) are constructed by mobile nodes without access point. since manet has certain constraints, including power shortages, an unstable wireless environment and node mobility, more power-efficient and reliable routing protocols are needed. the olsr protocol is an optimization of the classical link state algorithm. olsr introduces an interesting concept, the multipoint r...

Mobile environments are characterized by frequent variations in connection and bandwidth rates as well as by restrained resources on portable devices. This variability complicates data management and in particular, transaction execution. We consider that to deal with environment variability it is necessary to be adaptable. This paper proposes both a Mobile Transaction Service (MTS) and an Adapt...

This paper presents a new framework for building adaptive mobile applications in mobile computing environment. In mobile computing environment, network bandwidth and machine con gurations may be changed dramatically, and mobile applications should be adapted to various operational environments for being executed e ciently. Our framework solves many issues caused by adaptability and mobility in ...

abstract following the advances in mobile communication and information technology, smart phones have been used in a wide variety of commercial, social, entertainment, file sharing and health transactions and applications. the current procedures in healthcare environment for patient registration, appointment scheduling and payment are time consuming and somehow tiresome. traditionally, patients...

Recent communications environment significantly expands the mobile environment. The popularization of smartphones with various mobile services has emerged, and smartphone users are rapidly increasing. Because of these symptoms, existing wired environment in a variety of mobile traffic entering to mobile network has threatened the stability of the mobile network. Unlike traditional wired infrast...

the increasing penetration rate of mobile phone, with specific characteristics of this medium, such as almost everywhere with the audience, has attracted companies' attention to it as an advertising channel. mobile devices facilitate highly customized marketing communication in terms of person, time location and context so numbers of companies that use this medium for communicating with th...

In this paper, we proposed a secure mobile virtual computing environment for agent handshake. In mobile virtual computing environment, agent handshake often appears in mobile virtual computing, we conclude that problem into a basic secure problem. In this paper, we propose an ID-based one round authenticated group key agreement protocol with bilinear pairings for solving agent handshake problem...

Many banks in Saudi Arabia are starting to offer banking services through mobile phones. However, not many studies investigate the factors that may help the bankers to design mobile services, which are suitable for and adoptable by bank customers. This study fills this gap and examines a number of factors affecting the mobile banking adoption. Using Diffusion of Innovation as a baseline theory,...
