TL;DR: The 2M's and 7C's are proposed as a new framework for mobile commerce interfaces, and two new elements (2M's) are identified: mobile setting and mobile device constraints.
Abstract: The rapid growth of mobile telephony has fueled the expansion of the mobile Internet as a foundation for mobile commerce. Proponents claim that mobile commerce will surpass electronic commerce in growth and scope, but there is as yet no commonly accepted framework for the study of interface design for mobile commerce. Using Rayport and Jaworski's 7C's--the seven design elements of a customer interface (context, content, community, customization, communication, connection, and commerce) --as a reference framework, interfaces for mobile commerce and electronic commerce are compared. Two new elements (2M's) are identified: mobile setting and mobile device constraints. These 2M's substantially affect the design of each of the 7C's. Therefore, the 2M's and 7C's are proposed as a new framework for mobile commerce interfaces. Based on this, previous research is analyzed and suggestions for future research are generated.

TL;DR: A multi-level model to explain e-business adoption by service firms is proposed and found external competitive pressure, innovation orientation, financial slack, and IT resources were found to be associated with two measures of e- business adoption.
Abstract: E-business is rapidly spreading in service industries. Firms that adopt this innovative way to sell or deliver services and manage customer relationships must make technological and strategic changes. Firms in the same industry adopt e-business at different rates. Why do some firms actively implement e-business, and others take a more cautious attitude? Drawing on several research streams (innovation adoption research, institutional theory, strategic orientation theory, and upper-echelon theory), this article proposes a multi-level model to explain e-business adoption by service firms. The model was empirically tested using survey and interview data from travel agencies in Taiwan. External competitive pressure, innovation orientation, financial slack, and IT resources were found to be associated with two measures of e-business adoption. CEO risk-taking propensity and firm size also had an interaction effect on e-business adoption. Interviews with CEOs indicate that most travel agencies in Taiwan are not yet ready to apply mobile technologies in their daily business. The slow progress of mobile e-business was largely attributed to the limited capacity of mobile devices and the misfit between travel product characteristics, consumer behavior, and current mobile solutions.

TL;DR: This article proposes and discusses some novel architectures able to provide internetworking between WLAN and 3G networks, and meet the requirements of the most common internetworking scenarios.
Abstract: The intense wireless LAN standardization and R&D activities worldwide, combines with the recent successful deployment of WLANs, provide prime evidence that WLAN technology will play a key role in the fourth generation of mobile data networks. In this context, there is a strong need to integrate WLANs with 3G mobile data networks and develop hybrid mobile data networks capable of ubiquitous data services and very high data rates in strategic locations. This article addresses this need by proposing and discussing some novel architectures able to provide internetworking between WLAN and 3G networks, and meet the requirements of the most common internetworking scenarios. These architectures can enable 3G subscribers to benefit from high-throughput IP connectivity in hotspots and also to attain service roaming across several radio access technologies, such as IEEE 802.11, HiperLan/2, ULTRAN, and GERAN.

TL;DR: This work presents a synchronization framework for personal servers delivered in the form of user scenarios, derived system requirements, design decisions and a software components structure, and a high-level object-based storage API has been defined.
Abstract: The recent growth in the mobile device market has proven the feasibility of mobile storage based consumer electronics products. One of the key features of personal mobile storage devices is the ability to synchronize content and metadata with other mobile and stationary devices. The main problem addressed is automatic data exchange and synchronization in the domain of personal mobile storage devices or personal servers. We present a synchronization framework for personal servers delivered in the form of user scenarios, derived system requirements, design decisions and a software components structure. The synchronization framework was validated through a working prototype which shows added functionality, such as: connectivity with various types of devices from different vendors, synchronization based on user preferences, content-aware synchronization filtering. In order to abstract from implementation specifics of different network protocols, a high-level object-based storage API has been defined.

TL;DR: Mobile-D as discussed by the authors is an agile development approach called Mobile-D. This approach is based on four case studies and can be used for mobile application development, however, it is not suitable for large scale applications.
Abstract: Mobile phones have been closed environments until recent years. The change brought by open platform technologies such as the Symbian operating system and Java technologies has opened up a significant business opportunity for anyone to develop application software such as games for mobile terminals. However, developing mobile applications is currently a challenging task due to the specific demands and technical constraints of mobile development. Furthermore, at the moment very little is known about the suitability of the different development processes for mobile application development. Due to these issues, we have developed an agile development approach called Mobile-D. The Mobile-D approach is briefly outlined here and the experiences gained from four case studies are discussed.

TL;DR: This paper examines the state of the state-of-the-art in network mobility support by considering typical network mobility scenarios and identifying the characteristics that require new solutions, and reviewing some of the current approaches.
Abstract: Providing unperturbed Internet connectivity to mobile hosts has been studied in the IETF for some years now, and protocols such as Mobile IP and Mobile IPv6 have been developed. We are now witnessing the emergence of mobile networks, namely a set of hosts that move collectively as a unit, such as on ships and aircrafts. The protocols for mobility support therefore need to be extended from supporting an individual mobile device to supporting an entire mobile network. In this paper we examine the state-of-the-art in network mobility support. We first motivate the problem by considering typical network mobility scenarios and identify the characteristics that require new solutions. We then study the design requirements of the protocols that support network mobility. Thereafter, we review some of the current approaches for network mobility support, and discuss their strengths and weaknesses in addressing the design requirements. We conclude by identifying some open research issues in the realization of mobile networks.

TL;DR: The results of the studies show that Mobile Probes are a promising way to conduct user studies.
Abstract: This paper describes a new digital user study tool called Mobile Probes. Mobile Probes arose from a need to develop contextual and dynamic self-documenting tools for studying people's actions in mobile contexts. The technology used in the pilot study was based on dual band mobile phones with GPRS connections and an external accessory digital camera. A system was also developed for sharing and sorting the data. The system was implemented with Java software to enable the device to send and receive data, and PHP scripting to send and edit the questions and to view the answers through a dynamic web server. Another pilot study was conducted with a flexible platform that operates a spatio-temporal mobile log. The results of the studies show that Mobile Probes are a promising way to conduct user studies. Ideas for future development of the tool are discussed.

TL;DR: This work designs, implements and evaluates Mobile OGSI.NET, which extends an implementation of grid computing, OGSI, to mobile devices, and uniquely supports the hosting of grid services on the device.
Abstract: The problem with the grid is that it does not currently extend completely to devices, because these devices are not viewed as having sufficient capability to be both clients and services. We design, implement and evaluate Mobile OGSI.NET, which extends an implementation of grid computing, OGSI.NET, to mobile devices. Mobile OGSI.NET addresses the mobile devices' resource limitations and intermittent network connectivity, factors which differentiate them from traditional computers. Because Mobile OGSI.NET uniquely supports the hosting of grid services on the device, Mobile OGSI.NET is an important step toward making the mobile device a first-class entity in grids based on OGSI or the Web Services Resource Framework (WSRF).

TL;DR: The study shows that the new technique is many times better in reducing mobile communication and server processing costs and also makes the new approach highly adaptive to the heterogeneity of mobile objects.
Abstract: We consider in this paper how to leverage heterogeneous mobile computing capability for efficient processing of real-time range-monitoring queries. In our environment, each mobile object is associated with a resident domain and when an object moves, it monitors its spatial relationship with its resident domain and the monitoring areas inside it. An object reports its location to server whenever its movement affects any query results (i.e., crossing any query boundaries) or it moves out of its resident domain. In the first case, the server updates the affected query results accordingly while in the second case, the server determines a new resident domain for the object. This distributive approach is able to provide accurate query results and real-time monitoring updates with minimal location update and server processing costs. In addition, the new scheme allows a mobile object to negotiate a resident domain based on its computing capability. Thus, a more capable object can have a larger resident domain reducing its chance of having to request a new resident domain because of moving out of it. This feature makes the new approach highly adaptive to the heterogeneity of mobile objects. In our performance study, we compare it with an existing approach using simulation. The study shows that the new technique is many times better in reducing mobile communication and server processing costs.
