Abstract
Wireless networks are being deployed in a wide range of communication scenarios. Calculus of Wireless Systems [8] is introduced for specifying the behaviour of wireless communication. It contains several interesting features, including local broadcasting, half-duplex channel and transmission interference. In this paper we explore an observation-oriented semantics for the calculus, which can be used to study network equivalence. We investigate the observation-oriented semantics of wireless networks based on its basic components. A wireless network is specified as a set of nodes running in parallel, which are classified into four different types according to their states. The behaviour of a node is determined by its state with its environment, i.e., nodes which are located close to it. Hence a trace is introduced to record the execution as well as the corresponding environment update of a node. Based on traces of a set of nodes, the behaviour of a network composed of these nodes can be deduced. We also investigate a set of algebraic laws based on the observation-oriented semantics.
