Aprocess whichdetermines thephysical locations of nodesinawireless sensor networks iscalled self-localization. Self- localization iscritical formedium-tolarge-scale sensor networks because manuallocalization orpre-positioning isoften impossible duetotimerequirements, costconstraints orinherent limitations ofdeployment. Mostpreviously proposed algorithms totheprob- lemareunabletolocate sensor nodesaccurately. Furthermore, theestimated location isverysensitive totheranging error. In thispaper, we… CONTINUE READING
