%X To reduce the large communication cost of SDGPSN(Scalable and Distributed GPS free Positioning for Sensor Networks),the establishment of local coordinate system and global coordinate system in SDGPS was improved.The modified algorithm was described in this paper.Result of the simulation shows the modified algorithm is better than the original in terms of communication costs,and is more suitable for localization of sensor nodes in the WSN in which mobility of the sensor nodes is low.
