In this paper, we enable the coexistence of multiple wireless body area networks (BANs) using a finite repeated non-cooperative game, in which BANs are rational players but act selfishly. A game-theoretic based transmit power control scheme employing a novel utility function is proposed to maximize each network's packet delivery ratio (PDR) at low transmit power. The proposed utility function penalizes players with high transmission power, which reduces the interference caused to other coexisting BANs. Considering the purpose of inter-BAN interference mitigation, PDR is expressed as a compressed exponential function of inverse signal-to-interference-and-noise ratio (SINR), so it is essentially a function of transmit powers of all coexisting BANs. It is proven that a unique Nash Equilibrium (NE) exists and hence there is a subgame-perfect equilibrium, considering best-response at each stage independent of history. Realistic and extensive on- and inter-body channel models are employed. Results confirm that the effectiveness of the proposed scheme in better interference management, greater reliability and reduced transmit power, comparing with other schemes commonly applied in BAN.
