A trust degree of node based on aware routing protocol for wireless sensor network

To increase the energy efficiency of sensor nodes and ensure the accuracy of data transmitting, A Trust Degree of node Based on Aware Routing Protocol for Wireless Sensor Networks (TDAR) has been proposed. Based on the energy aware mechanism, TDAR algorithm builds node trust degree function and sets threshold of energy for changing transmitting node, so transmit node with higher link quality and less even no congestion can be chosen, the routing can also dynamic local adjust. Simulation results show that, TDAR can ensure lower end-to-end delay, improve the reliability of data transmitting in networks, and extend the network lifetime significantly.
