Applying Event-Driven Architecture to Mobile Computing

Complex event processing (CEP) has been an area of intensive research in recent years. Similarly, mobile devices such as smart phones, tablets and laptops are widespread nowadays. Consequently, the integration of CEP into mobile computing is a natural idea. In this paper, we present MetaXA, an event-driven architecture (EDA) with CEP specifically designed for mobile devices, along with its application scenarios in mobile computing: notification distribution and theft detection. Among the main enhancements of MetaXA over previously published work are enabling CEP on mobile devices and leveraging a lightweight yet still platform-independent communication protocol (viz., XMPP). In addition, MetaXA features real-time communication patterns and a publish-subscribe mechanism. MetaXA is implemented on different mobile platforms: Android and Windows Phone.
