Artificial Life models have consistently implemented communication as an exchange of signals over dedicated and functionally isolated channels. I argue that such a feature prevents models from providing a satisfactory account of the origins of communication and present a model in which there are no dedicated channels. Agents controlled by neural networks and equipped with proximity sensors and ...

We address the problem of simulating an arbitrary binary interactive first-order Markovian protocol over a pair of binary symmetric channels with crossover probability ε. We are interested in the achievable rates of reliable simulation, i.e., in characterizing the smallest possible blowup in communications such that a vanishing error probability (in the protocol length) can be attained. Whereas...

Wireless technology is experiencing spectacular developments, due to the emergence of interactive and digital multimedia applications as well as rapid advances in the highly integrated systems. For the next-generation mobile communication systems, one can expect wireless connectivity between any devices at any time and anywhere with a range of multimedia contents. A key requirement in such syst...

With the increasing demand for interactive services, it is important to investigate joint uplink/downlink resource allocation scheme in wireless networks, because the performance of the interactive service is determined by uplink and downlink jointly. In this paper, we propose a joint uplink/downlink resource allocation (RA) scheme in wireless orthogonal frequency division multiple access (OFDM...

In this paper, we consider distributed testing problems with interactive encoders, which allow interactive communications among encoders so that each encoder can utilize messages from other encoders for encoding. We first focus on a special case of testing against independence and design a scheme that enables each encoder to take advantage of extra information from other encoders for encoding. ...
