The existing secure routing protocols for ad hoc network are mainly based on bi-directional and symmetrical links, however, because of the special digital signals transmission equipments, which have different physical characteristic such as power range, there are many asymmetrical links in true wireless networks, so the successful authentication ratio is limited, even they can't work in some extreme circumstance. This paper proposes a bridge nodes based secure link state routing scheme-BSOLSR to solve the asymmetrical link problem. The simulation presents that the successful authentication ratio is enhanced and the average length of routing paths is shorter than that of SOLSR, which is important to the communication efficiency and networks performance.
