TOA [@Akcan_2006a] finds the distance between a transmitter and a receiver using one way propagation delay by exploiting the relationship. Accurate Distance Estimation between Things: A Self-correcting Approach between the light speed and the carrier frequency of the signal. However, TOA positioning requires an accurately synchronized clock as 1.0 μs error in time equals to 300 meters in terms of distance [12]. TOA will not be used for low cost devices because the high accuracy clock costs quite a lot. It is difficult to say that TOA will be widely applied to solve the accurate positioning problem.
