Semi-dynamic Hawk and dove game, applied to power control [PDF]

open access: yes, 2012
In this paper, we study a power control game over a collision channel. Each player has an energy state. When choosing a higher transmission power, the chance of a successful transmission (in the presence of other interference) increases at the cost of a ...
