Abstract: It is very difficult to get the security in sensor networks because of the limited resources of nodes and the wireless communication between nodes. A double security-based routing algorithms was proposed based on the existed security arrangement and low power consumption multipath.The existed security arrangement can provide security to some certain case and multipath can provide more security even when security arrangement failed. Theoretic analysis and simulation results show that the new algorithm has better performances.
