Chasqui: Asynchronous Communication Middleware Design Affording Contingent Routing, Leveraging Peers and Mobility

As Smart Environments expand and wireless connectivity is assumed to be a given, the consequences and cost of losing connectivity increases. By sharing diverse communication resources among heterogeneous devices and redistributing messages from problematic network types to available connections, the chances of eventually delivering an application\u27s message to one or more recipients can be increased, despite challenges faced by the source device. This thesis introduces a design and prototype for a middleware-based message persisting and passing system allowing application developers to associate contingencies for routing messages with the messages themselves. The generic design can be implemented across various platforms and device classes. Use of plug-ins allows for inclusion of emerging technologies and customization of deployments to leverage a host device\u27s available resources, including peer-to-peer channels
