چکیده

We model the interaction of several radio devices aiming to obtain wireless connectivity by using a set of base stations (BS) as a non-cooperative game. Each radio device aims to maximize its own spectral efficiency (SE) in two different scenarios: First, we let each player to use a unique BS (BS selection) and second, we let them to simultaneously use several BSs (BS Sharing). In both cases, we show that the resulting game is an exact potential game. We found that the BS selection game posses multiple Nash equilibria (NE) while the BS sharing game posses a unique one. We provide fully decentralized algorithms which always converge to a NE in both games. We analyze the price of anarchy and the price of stability for the case of BS selection. Finally, we observed that depending on the number of transmitters, the BS selection technique might provide a better global performance (network spectral efficiency) than BS sharing, which suggests the existence of a Braess type paradox.

One of the main challenges in Wireless Sensor Networks is the limited energy of nodes which can cause to reduce the lifetime of nodes and whole network respectively. Transmissions between the nodes consumes most of the nodes' energy so minimization of unnecessary transmissions can led to reduction of energy consumption. Therefor routing protocols designed based on optimal energy consumption are...
