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.
