This paper deals with the stochastic stability of networked control systems with the presence of network-induced delay and transmitted data dropout. Based on Lyapunov approach, sufficient conditions for the mean-square stability of the networked control system are derived subject that the sequence of transmission interval is driven by an identically independently distributed (i.i.d.) sequence and by a finite state Markov chain, respectively. Stabilization controllers are constructed in terms of linear matrix inequalities correspondingly. An example is provided to illustrate our results
