We provide in this paper three algorithms that enable the sensor nodes of a Wireless Sensor Network (WSN) to deter- mine their location in presence of neighbor sensorsthat may lie about their position. Our algorithms minimize the num- ber of trusted nodes required by regular nodes to complete their process of localization. The algorithms always work for a given number of neighbors provided that the number of liars is below a certain threshold value, which is also de- termined.
