LATTE: Location And Time Triggered Email

Abstract

Computer users, especially mobile ones, have developed a significant dependency on electronic communication. Enhancing the capabilities of such communication by adding an awareness of context such as location and time increases the quality and intuitiveness of the services available to the mobile user. This paper describes the design and implementation of a context-aware messaging system called LATTE (Location And Time Triggered Email). LATTE is based on the email paradigm, and extends it to include dynamic consideration of location and time to determine the appropriate recipients for a message. It uses SMTP (Simple Mail Transfer Protocol) for message delivery and an event middleware as the underlying communication infrastructure.
