| Abstract: | The error in the DV-Hop localization algorithm is primarily in computing the distance between unknown and anchor nodes.Using distance geometry constraints and the Cayley-Menger determinant in two-dimensional space,the distance between unknown and anchor nodes were optimized and corrected.The conditions of distance geometry constraints successfully reduced the error of distance measurements between unknown and anchor nodes,and node localization was determined using trilateration.Simulation results show that ... |
