A Stackelberg-Game-Based Power Control Algorithm for Wireless Mesh Networks
Algorithm 2
Stackelberg-game-based power control algorithm (SGPCA).
Begin | Input: The strategy set , utility function ; | Output: Optimal transmission power set; | When node needs to send data to adjacent node, it queries the cumulative interference | of the destination node from the interference information table firstly, and selects a proper | transmission power level using (20) based on the cumulative interference of the destination and | the distance to the destination. The node transmits data with the selected | transmission power level ; | Based on the received signal strength and the average cumulative interference , according | to the Stackelberg Subgame Perfect Nash Equilibrium, the receiving node transmits power | emendation instruction to the interfering nodes and the sending node; | The interfering node and the sending node adjusts its transmission power to optimize its | utility function based on the received power adjust instruction. | Circulation steps and , until the two game objects’ transmit power achieve steady state. | End |
