The topology structure of wireless sensor networks can be adjusted by varying the transmitting power of each node to gain better network properties. In this paper, we present a distributed strategic game-based equilibrium (SGBE) topology control algorithm to optimize each node's transmitting power. Through playing game in SGBE algorithm, each node can obtain its comparatively greatest profit, which bases on the profit function constructed by transmitting power, node-degree expectation and connectivity factor of the network. The resulting topologies could effectively avoid bottleneck nodes emerging. The theoretical analysis and simulation experiments show that, SGBE could converge to steady state of Nash equilibrium with a good convergence speed, and it has good characteristics of energy equilibrium, robustness and fault-tolerance.
