“…This is due to the fact that, when x is higher than such a threshold, the silence duration is large enough to cause an increase in the transmission delay and, consequently, a decrease in the transmission capacity. This is a well known result in timing channel communications [22]. In Fig.…”

The timing channel is a logical communication channel in which information is encoded in the timing between events. Recently, the use of the timing channel has been proposed as a countermeasure to reactive jamming attacks performed by an energy-constrained malicious node. In fact, whilst a jammer is able to disrupt the information contained in the attacked packets, timing information cannot be jammed and, therefore, timing channels can be exploited to deliver information to the receiver even on a jammed channel.Since the nodes under attack and the jammer have conflicting interests, their interactions can be modeled by means of game theory. Accordingly, in this paper a game-theoretic model of the interactions between nodes exploiting the timing channel to achieve resilience to jamming attacks and a jammer is derived and analyzed. More specifically, the Nash equilibrium is studied in the terms of existence, uniqueness, and convergence under best response dynamics. Furthermore, the case in which the communication nodes set their strategy and the jammer reacts accordingly is modeled and analyzed as a Stackelberg game, by considering both perfect and imperfect knowledge of the jammer's utility function. Extensive numerical results are presented, showing the impact of network parameters on the system performance.

“…Covert timing channels, that coexist along traditional data channels, constitute a means of secretly transmitting information, and can be exploited by compromised systems to convey sensitive information without being detected. More recently timing channels have been proposed as a means of improving the energy efficiency of energy-constrained networks [8] [9], such as satellite networks [10], intra-body sensor networks [11], and nanonetworks [12].…”

The proposed standardcompliant enhancement, BLE-TC (BLE with Timing Channels), improves the energy efficiency of an energy-constrained connectionless BLE transmitter by encoding additional information in the interarrival time between BLE advertisements. BLE-TC is analytically compared to the connectionless BLE standard. Using realistic timing noise that is empirically determined through a proof-of-concept-implementation, the results indicate that more than 10% improvement in energy efficiency can be achieved for low-throughput applications, such as smart metering and environmental sensing for smart cities.
