Abstract

Active Messenger (AM) is a software agent that dynamically filters and routes e-mail to a variety of wired and wireless delivery channels, monitoring a message's progress through various channels over time. Its goal is to ensure that desired messages always reach the subscriber, while decreasing message volume when the user is less reachable through location awareness. AM acts as a proxy, hiding the identity of the multiple device addresses at which the subscriber may be found and caches channels to guarantee seamless information delivery in a heterogeneous network. Our previous experience with mobile messaging influenced the initial requirements and design of AM. We describe the operation and evolution of AM to meet changing user needs, and how our own communication patterns and expectations have changed as we relied increasingly on mobile delivery.
