There are always VANETs malicious nodes attempt to disrupt the message during normal delivery in the routing protocol of VANETs (Vehicular Ad hoc Networks). At the same time due to the dynamic changes of the vehicle, so that the topology of VANETs changes rapidly, it is very easy to make the communication link of vehicles attacked, or there is no reliable disconnection phenomenon. Based on this, it presents a secure and stable cooperative with node VANETs routing protocols (RSVR). First regular intervals to detect signal strength, residual energy and interface queue length, and then check the data transmission, while the message load and transfer process certificate for authentication, and then set the collaborative monitoring message passing node in the routing protocol, for messages can not be delivered to the destination node, which will serve as the task of passing messages, and adjust the final routing allows data transmission can selectively defense, or selective forwarding data. Experimental results show that RSVR packet delivery rate increase 15%, to consider combining overhead and latency, etc., it come in a wide range of node RSVR intensive environment, that has better reliability and security.
