The smartphone market and the technology of mobile networking have been quite mature. Undoubtedly, smartphones have become an essential communicative tool in people's daily life. The rapid prevalence of smartphones can be attributed to a variety of factors. The mobile operating system (mobile OS), the so-called mobile platform, is definitely the most crucial factor. To probe into potential factors...
In this paper, we explore the problem of supporting efficient access to social media contents on social network sites for mobile devices without requiring mobile users to be online all the time. We propose and implement a broker/proxy based architecture that stages data at a broker/proxy, and selectively downloads to the mobile device only those contents that have a high likelihood of being viewed...
Mobile bank is a combined production of radio communication technology and bank operations. However, problems from the secure aspect restrict its development. By analyzing the security requirements of mobile bank and researching PKI and its application based on smart card, the framework of secure access system based on PKI with smart card for Mobile Bank is designed for eliminating secure problems...
In the study of the wireless mobile network, Random waypoint mobility model (RWP) and its generalization, nonuniform RWP (NU-RWP) are two of the most widely used mobility models. A useful property in NU-RWP, namely the inter-arrival time (IAT) is studied in this paper. We analytically derive the relationship between waypoint distribution and IAT, and propose two estimation schemes for the evaluation...
Message Ferrying (MF) is a recently proposed scheme to restore a Mobile Ad Hoc Network (MANET) from partitioning. Despite of the effectiveness in partition restoration, it sometimes suffers from long delay caused by the poor design of ferry route. The Message Ferry Route (MFR) problem has earlier been studied to minimize this drawback of MF schemes. In this paper, we argue that a dynamic way of determining...
In this paper, we propose a fully distributed scheme that uses a subset of nodes, namely ferries, to perform geographical broadcast tasks in a Mobile Ad Hoc Network (MANET). This scheme, referred to as the GeoFerry scheme, is to the best of our knowledge, one of the first scheme which adopts the deployment of ferries to address the geocast problem. Based on a theoretical analysis of the time intervals...
Todaypsilas access network is migrating towards broadband IP, fixed/mobile convergence and service convergence. Thus, the next generation access network (NGAN) requires a converged optical/wireless access network infrastructure, other than the existing architecture that connect to the cellular, broadband wireless, and optical access networks separately, which complicate the network and increase the...
