We introduce a new theoretical model of ad hoc mobile computing in which agents have restricted memory, highly unpredictable movement and no initial knowledge of the system. Each agent's memory can store O (1) bits, plus a unique identifier, and O (1) other agents' identifiers. Inputs are distributed across n agents, and all agents must converge to the correct output value. We give a universal construction that proves the model is surprisingly strong: It can solve any decision problem in NSPACE… CONTINUE READING
