%X A novel routing algorithm based on trustworthy core tree(TCTR) in WSN was proposed in this paper. It aims to prolong network lifetime as well as increase network security in a hierarchical-cluster sensornet. Cluster heads with higher residual energy and trust level Were elected from underlying sensor nodes. A minimum pathloss tree algorithm was borrowed to organize all cluster heads as a trustworthy core tree with sink node as tree root. Expanded the Trustworthy core tree to cover all nodes so that each node reports to sink node with a certain route. A trust model was integrated in TCTR to evaluate node's trust level and detect evil nodes. Simulation results testified the effectiveness of the algorithm in producing a longer network lifetime and a safer network.
