SINR Pricing in Non Cooperative Power Control Game for Wireless Ad Hoc Networks
Sanjay Kumar Suman, Dhananjay Kumar, L. Bhagyalakshmi · KSII Transactions on Internet and Information Systems · 2014
In wireless ad hoc networks the nodes focus on achieving the maximum SINR for efficient data transmission.In order to achieve maximum SINR the nodes culminate in exhausting the battery power for successful transmissions.This in turn affects the successful transmission of the other nodes as the maximum transmission power opted by each node serves as a source of interference for the other nodes in the network.This paper models the choice of power for each node as a non cooperative game where the throughput of the network with respect to the consumption of power is formulated as a utility function.We propose an adaptive pricing scheme that encourages the nodes to use minimum transmission power to achieve target SINR at the Nash equilibrium and improve their net utility in multiuser scenario.
