Aiming at problem that dynamic fluctuations of wireless signal in wireless sensor networks （WSNs） may cause problems that network link becomes unstable and coverage range becomes smaller, a kind of WSNs topology control algorithm based on TopDisc is put forward. Topology control parameters which control network topology optimization are introduced to adapt to change of wireless signal,process of topology constructing is given, simulation experiment of this algorithm is carried out. Results of simulation show that improved topology control algorithm can improve adaptability of WSNs to complex radio environment and utilization rate of resources and link reliability.
