Abstract

In this study, we propose an improved group location tracking scheme (GLS) called integrated GLS (IGLS) which, in addition to the group location registration of the GLS, sends an integrated group registration message to a virtual visitor location register (VVLR) instead of sending an individual group registration message. This integrated procedure of proposed scheme leads registration cost of group registration and group location registration to be reduced significantly. Numerical results demonstrate that our proposed IGLS outperforms conventional GLS and delayed GLS (dGLS). The IGLS can be applied effectively on public transportation systems such as subway, train and bus.
