The ubiquitous wireless networks make it become possible for people to access a variety of services anytime and anywhere through mobile devices such as smartphone and tablet. However, due to the diversity and complexity of services, the requirement for storage and computing capacity for mobile devices is becoming higher and higher. Mobile transparent computing is a fit for this scenario. In mobile...
Over the last few decades, the Internet has grown exponentially, bringing about hard questions about its future sustainability. At the same time, the proliferation of wireless and mobile devices with Internet connectivity has created a new landscape for a wireless future Internet. It is evident that in the emerging “Future Internet” (FI), wireless and mobile networking will remain significantly important,...
Rapid development has equipped mobile devices with heterogeneous wireless access capabilities. A lot of work has been done on WLAN-3G integration to support seamless connectivity and global roaming. Most recent research trends focus on interwork gateway or intersystem roaming framework. In this paper, we introduce an application framework providing seamless connectivity for mobile devices across heterogeneous...
Wireless networks and mobile devices, which had brought lots of convenience to our daily life and made us much easier to get information any time and any where, now had motivates the needs for efficient tools analyzing data streams. Data mining technology turned into a valid tool for us to make scientific decision. Data mining can transform vast data resource into available knowledge and information...
Mobility of users carrying mobile devices with access to wireless networks creates the need to provide uniform and immediate access to information. In this scenario, a new educational model, called Ubiquitous Learning, has been studied. In this model, the educational processes are related to the learner's situation, i.e. they are context-aware. This allows the access to educational resources be adapted...
Wireless networks based on the IEEE 802.11 standard have become very prevalent recently. Most of these networks support only nomadic mobility of wireless devices. However, in case of vehicle-to-infrastructure communications the mobile devices in the vehicles need to have the ability to quickly switch their association to a new access point (AP) when they move out of range of their initial access point...
Next Generation Wireless Networks (NGWNs) will be the convergence of fixed and mobile networking technologies, e.g., Ethernet, Wireless LAN, 2G/3G/4G, etc. This united ubiquitous network will consist of billions of mobile devices, each with multiple networking interfaces. These interfaces may belong to a set of diverse link layer technologies. Internet Protocol (IP) shall potentially be used as the...
Recent advances in communication technology enable the emergence of a new generation of applications that integrates mobile devices with classical high performance systems as part of a common computing environment. In such environments, keeping the coherence of shared data (distributed objects, for example) represents a real challenge as communications are strongly influenced by the performance and...
With the constant development of multimedia technologies and mobile devices, the demand of transmitting multimedia streams to mobile devices will be one of the major applications in wireless networks. But the categories of devices and user preference vary widely. How to provide appropriate multimedia streams to mobile terminals and how to process the received multimedia content in the user side will...
Wireless networks have contributed to the technological advance that popularized the use of mobile devices, and fostered the development of applications targeted to these devices. However, issues such as mobility and communication intermittency, as well as processing, storage and battery constraints demand changes in the traditional software testing process. This paper aims to present testing requirements...
The evolution of wireless networks and mobile devices has resulted in increased concerns about performance and security of mobile payment systems. In this paper we propose SA2pMP, a lightweight secured architecture for two-party mobile payments. SA2pMP employs a lightweight cryptography scheme that combines public key and symmetric key cryptography systems (ECDSA and AES), as well as a multi-factor...
With the advancement in mobile technology, many business activities can be conducted through wireless networks. M-commerce is experiencing rapid growth in terms of capabilities of mobile devices, services, applications, standards and network implementation. However, we are still facing some important factors that influence m-commerce adoption and development. The implications of these factors are...
Wireless technology is seen as a gradually popular information technology with such potency that it has changed the way we view IT. Through wireless network, many knowledge management activities occur in working places and in our daily activities. In the mobile environments, the important knowledge management is quickly acquired the right knowledge using mobile devices through wireless network. The...
Mobile advertising employs mobile devices such ascell phones and PDAs to transmit advertisinginformation to users. The chief difference betweenmobile advertising and traditional advertising is thatmobile advertising must employ wireless networks andmobile devices; as a consequence, apart fromadvertisement content, the factors affecting attitudetowards mobile advertising may also includeconsumers'...
In the area of mobile ad hoc and sensor networks, simulation became the evaluation method of choice. Due to the high number of variables - including transmission range, number of nodes, simulation area, mobility pattern-simulation settings vary largely from work to work, depending on the application scenario focused. The results for two simulations with identical setting, but different mobility models,...
With the advent of high bandwidth third-generation mobile networks and other wireless networks, grid computing has migrated from traditional parallel and distributed computing to pervasive and utility computing based on the wireless networks and mobile devices, which results in the emergence of a new computing paradigm named mobile grid. Data replication is widely used in mobile grid environments...
Cell phones are no longer merely used to make phone calls or to send short or multimedia messages. They more and more become information systems clients. Recent developments in the areas of mobile computing, wireless networks and information systems provide access to data at almost every place and anytime by using this kind of lightweight mobile device. But even though mobile clients support the Java...
For companies to establish their mobile commerce applications, the fundamental challenge is how to extend existing enterprise applications with mobile functionality in order to provide remote staff with real-time business data while at the same time avoiding alteration of existing system codes. Due to increased diversity of business data and mobile devices, many of current mobile commerce applications...
Mobile commerce (m-commerce) is a rather new field in the business world. It depends on wireless networks for accessing the Internet from mobile devices and for exchanging data between such devices. Wireless technologies on the one hand evolve rapidly and are met in many different applications. On the other hand a plethora of factors encourage market to make advances towards the m-commerce market...
Mobile commerce is undoubtedly become an omnipresent and active area in electronic payments. It allows mobile user to purchase things, pay bills or make a bet via mobile phone when on the move, anywhere and at any time. Unfortunately, several challenges in accountability and privacy properties have emerged with the widespread of m-commerce in recent years. Consequently, many public-key cryptography...
