We consider security issues in Cyber-Physical Systems (CPSs). A sensor node communicates with a remote estimator through a wireless channel which may be jammed by an external attacker. With energy constraints for both the sensor and the attacker, the interactive decision making process of when to send and when to attack is studied. We formulate a game-theoretical framework and prove that the optimal...
In this paper, we study power allocation in cognitive sensor networks where cognitive users (cognitive enabled sensor nodes) opportunistically share a common spectrum with primary users (licensed devices). We define an energy efficiency-oriented utility function as a new metric to evaluate power allocation. Consider that sensor nodes are self-interested to maximize their own utility, we formulate...
Vehicular Ad hoc Networks(VANETs) enable plenty of important applications for vehicles, such as accident prevention and traffic jam avoidance. However, VANETs can hardly provide reliable connectivity between vehicles, which makes data dissemination of the aforementioned applications extremely difficult. Compared with VANETs, 3GPP cellular networks(e.g., LTE), offer much more reliable connectivity...
Resource allocation is an important issue in cognitive radio networks. Optimizing this process is crucial for primary users (PUs) and secondary users (SUs) to maximize the performance of the whole network. In this paper, we investigate the RA-PS problem in cognitive radio networks, in which each PU acts as a relay for multiple SUs. We formulate this problem as a two-tier game. In the first RA-Game,...
