A Wireless Sensor Networks Based on Multi-angle Trust of Node

Facing the security threats and the energy shortage, a multi-angle trust mechanism for nodes in wireless sensor networks was proposed, which extended the previous trust model only base on communication trust. With adding the sensing data and the node´s energy in the factors of trust assessment, and new trust models to calculate the trust values of the sensed data and the node´s energy, a more reliable wireless sensor networks could be established. Simulation experiment results show that, one model only based on communication trust is not enough to decide on the trustworthiness of a node. Hence we need to develop new techniques to combine the communication trust, data trust and energy trust into a unite trust.
