A simple swap technique and enhanced GTT location database management scheme

In this paper, we have proposed a location update scheme by applying swap technique and enhanced GTT in STP. This scheme achieves significant improvement in signalling costs compared to other location update schemes. This paper presents the details of this scheme and provides comparison results with other location database management schemes. The performance results clearly indicate that our proposed scheme is far superior to most other schemes and provides a 15-50% reduction in signalling cost when compared to GSM. The novelty of the proposed scheme is that it provides considerable reduction in signalling cost, and at the same time it is very simple and easy to implement.
