Abstract—This paper derives a Crammer Rao lower bound (CRLB) for wireless geolocation technique based on differential received signal strength (DRSS) measured parameter and factor graph framework. Then, the CRLB is derived by modifying the Fisher information matrix (FIM). In particular, the derivation inside the FIM focuses on Jacobian matrix having relationship between the target coordinate and the measured DRSS. Finally, the simulation results show that the derived CRLB is excellence with the lowest root mean square error (RMSE) curve. Index Terms—CRLB, DRSS, FIM, Factor Graph, Geolocation
