Seamless Handover by Optimal Route To Materialize ABC With heterogeneous B3GWN


The actual trend is to integrate complementary wireless technologies with overlapping coverage, to provide the expected ubiquitous coverage and to achieve the Always Best Connected (ABC) concept. Therefore, the continuation of an active call is proof to that trend, and can satisfied that trend by good handover management.This paper, focus on the vertical handover decision process and improvement of network performance when the user's position and optimum path are taken into account. From the results the improvement in handover time by(5-30msec) was materialize, well, reduce the memory size.
