title = "Reducing error propagation on anchor node-based distributed localization in wireless sensor networks",
abstract = "This paper proposes a scheme for reducing error propagation (REP) based on low-cost anchor node-based distributed localization (LADL) that are advanced localization schemes using connectivity information between nodes. Even though the localization accuracy of LADL is higher than that of previous schemes (e.g., DRLS), estimation error can be propagated when anchor node ratio is low. Thus after the initial position of each normal node is estimated by LADL, estimated position is corrected using anchor nodes located several hops away so that error propagation is reduced. The simulation results show that LADL with REP has higher localization accuracy and lower message transmission cost than DRLS. In addition, even though message transmission cost is increased, the localization accuracy of LADL with REP is higher than that of DRLS.",
