Benefit from the rapidly developing in hardware manufacturing technology and efficient software algorithms, wireless sensor networks have been widely used in many fields. Secure routing protocol in wireless sensor network has been an essential issue to consideration when security requirements are rising in deployments of sensor networks. But, in the early period, security aspects in routing protocol have not been given enough attention. So, many routing protocols of WSNs since design stage have not taken secure requirements in mind. In this paper, the authors proposed a secure routing protocol based on node reputation of wireless sensor network, and enlightened by the idea of ant colony optimization, the routing protocol named Reputation-Based Ant Secure Routing protocol (RBASR).
