Wireless sensor networks are usually deployed in the non-controlled environment without maintenance, facing problems of a general disclosure of information, information tampering, replay attacks, denial of service and other threats, and also facing the threat of the mass nodes being easily targeted by physical manipulation, with the information stored in the sensor nodes being taken and used for the manipulators to control a part of the network. Based on the studies of the collaboration of the ant colony system, a trust model based on biologically inspired (BTRM) trust in the cooperation mechanism is proposed for the use in wireless sensor networks. Some trust models of collaboration curently in use are analyzed, and a wireless sensor network based on BTRM collaborative trust simulation software features and software architecture is proposed. The principles and the implementations of the collaborative trust simulation system are discussed. The simulation shows the output average path length, the average satisfaction, the average deviation, which indicates an improved performance.
