英文摘要： Recently, intrusion detection, trust, and survivability in Wireless Sensor Networks (WSNs), due to their necessity, have been interesting for network researchers. Using game theory, in this project we attempt to solve several crucial issues including when to launch the Intrusion Detection System (IDS), how to make a trust decision, and how to predict the expected attacker behavior employed in the survivability evaluation. According to the characteristics of these issues, we will employ various games. The signaling game will be applied to construct the intrusion detection game based on the detection rate and the false-alarm rate of the IDS as well as the network-packet-loss rate, and then to determine the optimal strategy for launching the IDS. The evolutionary game will be used to set up the trust game based on fuzzy trust degrees of sensor nodes, and to disclose the dynamics of trust evolution of sensor nodes. We thus can found the theoretic foundation to form the WSNs trust mechanism. In addition, we will combine non-zero-sum stochastic game with Markov chain to explore the survivability model for the WSNs attacked. A novel method to evaluate the WSNs survivability will thus be generated. In order to supply these contents above, we will develop a WSNs security test platform upon OPNET. Our research results wil
