Abstract :
The double time difference of arrival (DTDOA) approach applying in the mobile ad hoc network can effective avoid the synchronization problem. This paper investigates the performance of techniques for DTDOA node localisation in mobile ad hoc network by using root of quadratic equation and Gauss-Newton algorithm in NLOS environments. The validity of DTDOA method is demonstrated in an example of a simple ad hoc network.
