Abstract: The linear propagation of the ion-acoustic waves (IAWs) in a dusty plasma consisting of Boltzmann-distributed electrons and ions, mobile charge fluctuating negative dust and charge fluctuating stationary negative dust has been theoretically investigated. It has been shown that the electron charge fluctuation is a source of dissipation, and is responsible for forming IA shock waves in such a dusty plasma. The basic features of the IA shock waves have been identified in this investigation which could be useful in understanding the properties of localized space dusty plasmas. It has been proposed to design a new laboratory experiment, which will be able to identify the basic features of the ion-acoustic shock waves predicted in this theoretical investigation.
