The value added process of mobile commerce value chain is studied. Technical aspect of mobile commerce has matured, however, development of any industry needs a stable and sustainable benefit pattern, thus the research of value chain could find and enforce the mobile value chain increment, besides pushing the industry forward. First, the activities of different stages in the mobile commerce are analyzed...
With the number increment of mobile computing equipment, the invalidation of equipment and broadcasting information because of wireless bandwidth, communication quality and too long scheduling queue that badly influence the system computing performance. Mobile cache is a good technology to solute this difficult problem. Considering the priority problem of broadcasting queue generated by data invalidation...
In the mobile era, mobile advertising is essential and has been developing very fast. Marketers are eager to turn to mobile viral advertising for benefiting from initially targeting customers. In this paper, we propose a computational model to reconstruct the spreading of advertisements in social networks. Using this computational model as a test-bed and running a series of virtual experiments, we...
Mental health represents a social and economic problem in all European Union (EU) member nations. Although cognitive behavioral therapies (CBT) have provided an effective approach to the treatment of depression, several issues currently remain unresolved. This paper introduces a novel mobile system that provides several useful functions to improve the delivery of treatments for depressive conditions...
This paper addresses context issues in pervasive mobile computing and presents a semantic context model to support location based cooperative mobile applications. In this paper, a mobile learning prototype has been discussed as a scenario for evaluation of the context model. A Bluetooth based wireless solution is introduced for the purpose of integrating this model with the current e-learning system...
Contextual computing research aims to develop systems incorporating awareness of and the ability to adapt to user context. A dictionary definition of context may state: "the context of an idea or event is the general situation that relates to it and which helps it to be understood." In contextual computing, context should include information to enable systems to achieve timely and precise...
