The authentication method in wireless sensor network based on trust model

Existing wireless sensor network are developing rapidly and soon will occupy a dominant place among the data collection and communication. The remote location of the sensors and automatic operation increases their vulnerability to outside intrusions and attacks. Because of out of constant sensor supply the providing of authentication is quite challenging whereas the best protocols is negotiated sensor capabilities. The method of sensor authentication in the wireless sensor networks, which is based on a model of trust, is proposed.
