Abstract

Position estimation using Time of Arrival (ToA), Time Difference of Arrival (TDoA), and Angle of Arrival (AoA) measurements are the commonly used location techniques. These techniques, using location parameters received from different sources, are based on intersections of circles, hyperbolas, and lines, respectively. The location is determined using standard complex computation methods that are usually implemented in software and needed relatively long execution time. This paper consists of minimizing and simplifying the computing process in the Mobile Station (MS) during its geo-location phase needed especially for handover. This work considers designing EToA as extended version of ToA, following the same principle but using another aspect for the computational process.

3. Conclusion

In this paper, we presented EToA as geolocation technique to estimate the location of a MS for handover management. Performance evaluation is considered to demonstrate its efficiency during intercellular transitions, especially compared to IEEE 802.11 standard. As result, the proposed technique is sharply convergent within a reduced number of iterations (k < 10). Moreover, the implementation simplicity and low computational overhead constitute their major advantages. In perspective, the MS position accuracy will be considered as major future evaluation metric.
