Abstract: With the widespread application of wireless multimedia sensor networks, the issue of network reliability has attracted more and more attention. In this article, a new reliability evaluation method of wireless multimedia sensor network is proposed. The failure is regarded as a percolation process, and the percolation threshold is taken as the failure indicator in this method. Accordingly, instantaneous availability model of wireless multimedia sensor network is established combining percolation theory and Markov process on the basis of reliability characteristics analysis. By Laplace transformation, the analytic solution is worked out, and one numerical example is given to verify the model comparing with existing studies. Finally, numerical simulation analyses are used to show the impact of different parameters on instantaneous availability, and the ways to suppress fluctuations are obtained by comparing with fluctuation images.
