RESUMO
The Wireless communication networks are increasingly present in people`s lives. Talking to friends, listening music, watching television, buying things, are examples of activities that nowadays can be accomplished by a great variety of wireless networks. Modern mobile devices have a diversity of network interfaces, for users to choose from. Due to mobility offered by mobile devices, different types and scenarios of networks appear at every new location. Some proposals and solutions are been studied to allow users to choose the best network connection for a specific service utilization, depending on the current user`s task. But, few proposals are presented to allow network and service providers to provide these best connection. Mobility, user`s freedom of choice, variety of network connections and types of service are challenges that the providers are beginning to find. Moreover, the ability to attract new customers, increase your services sales volume and its consequent market share, are opportunities that arise in this new scenario. A multi- agent systems framework is proposed with the aim to examine this new scenario and exercise solutions that are useful both for customers, and for wireless network providers. Contextaware strategies for provider`s service pricing and for customer`s best choice of service provided are subject to review. In the solution, context information is represented in the ontology model proposed by DynaCIP and an algorithm for decision-making used by the agent is proposed, although the framework flexible the use of other algorithms. A framework instantiation for a next generation wireless networks scenario is implemented and discussed in the proposal.
