An operational semantics for a calculus for wireless systems

none2noIn wireless systems, the communication mechanism combines features of broadcast, synchrony, and asynchrony. We develop an operational semantics for a calculus of wireless systems. We present different Reduction Semantics and a Labelled Transition Semantics and prove correspondence results between them. A major goal of the semantics is to describe the forms of interference among the activities of processes that are peculiar of wireless systems. Such interference occurs when a location is simultaneously reached by two transmissions. The Reduction Semantics differ on how information about the active transmissions is managed. We use the calculus to describe and analyse a few properties of a version of the Alternating Bit Protocol.openI. Lanese; D. SangiorgiI. Lanese; D. Sangiorg
