# Mitigating Jamming Attacks Using Energy Harvesting

## TL;DR

This paper explores how energy harvesting can be used to counteract jamming attacks in wireless networks by turning interference into a resource, showing significant capacity gains.

## Contribution

It models the interaction between legitimate nodes and a jammer as a zero-sum game and demonstrates the potential of harvesting jamming energy to improve capacity.

## Key findings

- Legitimate nodes can neutralize the jammer using energy harvesting.
- Harvesting jamming interference can increase capacity by up to 95%.
- The proposed policy is not always a Nash equilibrium.

## Abstract

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.
