Embora a conectividade com a grande rede seja assunto resolvido para uma vasta gama de sistemas computacionais, temos nichos crescentes de objetos do dia a dia que estão adquirindo maiores funcionalidades em virtude do avanço constante da eletrônica embarcada. Neste trabalho apresentamos nossa solução de conectividade IP desenvolvida na plataforma EPOS, demonstrando a viabilidade de interconexão usando protocolos maduros e bem estabelecidos mesmo em sistemas altamente…

we introduce the premises for a trading system application-programming interface (API) based on a message-oriented middleware (MOM), and present the results of our research regarding the design and the implementation of a simulation-trading system employing a service-oriented architecture (SOA) and messaging. Our research has been conducted with the aim of creating a simulation-trading platform, within the academic environment, that will provide both the foundation for future experiments…
