  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.
