Infraestrutura para o desenvolvimento de aplicações com suporte à comercialização de serviços entre pares em ambientes pervasivos.

Abstract

The improvement of computational resources of mobile devices and the convergence of new features in these devices has created new opportunities for the world of pervasive computing. These new attributes, combined with ease of connectivity between them and the provision of mobile services has motivated the sharing of resources and billing between the users of these devices. Examples of services: the sharing of multimedia content, the electronics control and appliances, Internet access, others. Mobile applications that offer resource billing, most of them, have only online charging, with the need of an Internet connection to validate transactions. Other applications presents offline charging, but they are solutions that require specific hardware for its operation, which prevents the adoption of devices already on the market. Considering these aspects, this work presents an infrastructure for developing applications that supports service billing, which offers a new way of charging. The infrastructure allows billing in offline mode without the need for specific hardware to function. The work validation was performed by implementing a case study of a service for sending SMS messages, which sends text messages to mobile phones through file transfer, showing the support offered by the infrastructure for the development of mobile applications that provide the service billing.
