A computational model reflecting fundamental computational aspects of wirelessly communicating mobile processors is presented. In essence, our model is a deterministic Turing machine that can launch new processes among which a wireless communication via explicitly assigned channels must be programmed. We show that computations of such machines are polynomially time- and space-equivalent to the synchronized alternating Turing machines studied previously in the literature. This shows that nondeterminism can be completely eliminated from synchronized alternation at the price of introducing a program-driven communication among the respective processors.
