  In wireless multi-hop networks, the instability of the wireless links leads
to unstable networking. Even in the newly designed Software-Defined Wireless
Sensor Networks (SDWSN), similar problems exist. To further improve the
stability of SDWSN, we introduce a Link Quality (LQ) prediction model into the
SDWSN architecture. The prediction model is used to improve the stability
between neighbor nodes, and thus the stability of wireless multi-hop routes.
Simulation results show that the LQ prediction model can make reasonable
corrections to the reality wireless link model, which can well address the
restrictive nature of unstable links. As a result, by reducing the use of
unstable wireless links, the stability of the SDWSN network improved.
