Abstract：In order to solve the problem of wireless link instability in sensor network, based on the r-neighborhood graph model, this paper puts forward a robust adjustable topology control algorithm with steady links, named RAWSL. RAWSL algorithm sets the receive signal strength threshold as the limit of topology, which to avoided effectively the instability links, and by adjusting the value of parameters r to fit a variety of network robustness requirements. The experiment results show that, RAWSL algorithm not only ensures the entire connectivity, it also has higher robustness and lower delay characteristics.
