Mitigating Jamming Attacks Using Energy Harvesting
This addresses security vulnerabilities in wireless communication for network operators, though it appears incremental as it builds on existing game-theoretic frameworks.
The paper tackles the problem of jamming attacks in wireless networks by investigating energy harvesting as a countermeasure, where harmful interference is converted to increase transmit power, resulting in up to 95% average gains in Shannon capacity under high interference.
The use of energy harvesting as a counter-jamming measure is investigated on the premise that part of the harmful interference can be harvested to increase the transmit power. We formulate the strategic interaction between a pair of legitimate nodes and a malicious jammer as a zero-sum game. Our analysis demonstrates that the legitimate nodes are able to neutralize the jammer. However, this policy is not necessarily a Nash equilibrium and hence is sub-optimal. Instead, harvesting the jamming interference can lead to relative gains of up to 95%, on average, in terms of Shannon capacity, when the jamming interference is high.
