A Distributed Jamming Resource Assignment Scheme Based on Min-Max Algorithm

摘要

For an energy-constrained distributed jammer, a reasonable jamming resource assignment can prolong the system's lifetime and ensure a satisfying jamming effect. This paper treats wireless sensor networks as a distributed jammer and analyzes the optional amount of power transmitted by different sensors to successfully jam the target radar, while at the same, maximize system's lifetime. Based on the Optimization Theory, a power assignment scheme, MinMax, is proposed for that purpose. From the simulation, it is apparent that, with Min-Max, the power consumption is evenly-distributed between different sensors in a working round and thus a prolonged lifetime achieved. Adding two steps before and after that scheme, the new form of Min-Max is also effective in the situation where initial energy between different sensors is not the same.
