Study of Location Algorithm for Wireless Sensor Networks Based on Newton Iteration

摘要：

　　The TDOA localization algorithm for wireless sensor networks can help us measure the time differences of an unknown node to more anchor nodes,which establish nonlinear equation of the differential distance between unknown node and anchor node.Newton iteration is the crucial method for nonlinear equation numerical solutions,so using the Newton iterative method can better achieve nonlinear optimization in TDOA location.The simulation results indicate that the algorithm can meet the requirement of localization and possesses the preferable localization precision.
