Survivability Analysis of Wireless Sensor Network with Transient Faults

To the best knowledge of us, survivability for WSN has never been studied considering failure affects on network. We perceive the network survivability as a composite measure consisting of both network failure duration and failure impact on the network. In this paper we will study network survivability in unstably state: in this state, network is affected by the failures that occur temporarily and instantly also may occur several times. In other words, the main characteristics of these failures are their frequency and being temporary. In this paper we will propose a survivability model for network in unstable state that is based on network availability. This availability model, presents frequent availability of a route. During this paper, first we acquire an availability model for network in unstable state that shows frequent availability of a node. We also use Markov model for nodes to show their transmission state according to availability model. Then we use a computational method for proving our model.
