UTP Semantics for rTiMo
rTiMo is a real-time version of TiMo (Timed Mobility), which is a process algebra for mobile distributed systems. In this paper, we investigate the denotational semantics for rTiMo. A trace variable tr is introduced to record the communications among processes as well as the location where the communication action takes place. Based on the formalized model, we study a set of algebraic laws, especially the laws about the migration and communication with real-time constraints. In order to facilitate the algebraic reasoning about the parallel expansion laws, we enrich rTiMo with a form of \(guarded \ choice\). This enables us to convert every parallel construct to a guarded choice.
