Programmable orchestration of time-synchronized events across decentralized Android ensembles

Orchestrating a time sensitive computation across an ad hoc ensemble of Android devices is surprisingly challenging in spite of the OS´s support for automated network time synchronization. In fact, the lack of access to programmatic nor end-user control pushes the responsibility of implementing fine-grained time synchronization to the application development level. In this paper, we extend CoMingle, a distributed logic programming framework designed for orchestrating Android ensembles, with explicit time annotations and built-in network time synchronization support. The result is a powerful programmable orchestration framework for developing apps that exhibits time-synchronized events across an ensemble of Android devices.
