My PhD research focused on investigating programming language support to deal with the effects engendered by partial failures in mobile ad hoc networks (MANETs). In MANETs many partial failures are the result of temporary network partitions due to the intermittent connectivity of mobile devices. Some of these failures will be permanent and require application-level failure handling. However, it is impossible to distinguish a permanent from a transient failure. Leasing provides a solution to this problem based on the temporal restriction of resources. | My PhD research focused on investigating programming language support to deal with the effects engendered by partial failures in mobile ad hoc networks (MANETs).

+ | The dynamic nature of ambient oriented applications makes it impossible to structure them as monolithic programs with a fixed input and output. Instead, a distributed event-driven architecture is required. Current event-driven architectures require distributed application components to react to events via a carefully crafted network of observers, event handlers or callback mechanisms which are scattered throughout the application code and can be triggered at any point in time. Such architectures are hard to develop, understand and maintain in all but the most trivial cases. | ||
