Ambient-Oriented Exception Handling

Writing ambient-oriented software for mobile devices connected through wireless network connections provides new challenges in the field of exception handling. It involves dealing with issues such as asynchronous communication, moving hardware and software, only to name a few. Building on an analysis of the fundamental differences between mobile networks and their stationary counterparts, this paper establishes a set of criteria for an ambient-oriented exception handling mechanism. We subsequently present ambient conversations, a novel distributed exception handling mechanism that adheres to the prescribed criteria, and describe its realisation in the experimental ambient-oriented programming language AmbientTalk.
