AbstractIn wireless localisation, time-based Location Determination Technology (LDT) with minimum error is one of the crucial techniques that can be used to improve resource management and quality of services. This study aims to improve the location accuracy of mobile user by using a hybrid timebased LDT. In this paper, minimising of the mobile estimation location error by using hybrid trilateration technology based on Time of Arrival (ToA) and Centroid Triangular Algorithm (CTA) has been discussed. It has been observed that this hybrid technique can be considered as an optimal solution for minimising the localisation error of mobile user which is located in a vicinity of the heterogeneous network environment. Based on simulations, the constructed model has resulted in a better location error distribution, and the localisation error can be minimised and satisfied the E911 requirements.
