An Efficient Location Management Scheme for Hybrid Wireless ATM Networks

Location management is one of the most important aspects in the realization of mobility in wireless networks. Following developments of ATM (Asynchronous Transfer Mode) technology, more core networks become ATM-based. Therefore, the demand of mobility on wireless networks with ATM backbones is increasing. In recent years, several location management schemes have been proposed for classical wireless ATM networks. Most of these proposals assume that a wireless ATM network is constructed by End-user Mobile ATM Switches (EMAS). However, current ATM networks only consist of normal ATM switches that are not mobility enabled. In this paper, we propose a location management scheme for hybrid wireless ATM networks. The proposed scheme can be applied on hybrid wireless ATM networks constructed from both normal ATM switches and EMASs. Following a description of the proposed location management An Efficient Location Management Scheme for Hybrid Wireless ATM Networks 2 scheme, an analysis is presented on cost performance. Numerical results show that the proposed scheme is more cost effective than a generic GSM/IS-41 based location management scheme.
