Efficient location management for hybrid wireless ATM networks: architecture and performance analysis
نویسندگان
چکیده
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 are becoming ATM-based. Therefore research into location management schemes for wireless networks with ATM cores is attracting more attention. In recent years several location management schemes have been proposed for classical wireless ATM networks, which have end-to-end native ATM connections. Most of these proposals assume that a wireless ATM network is built using 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 present a location management scheme for hybrid wireless ATM networks, which have an ATM based core and IP based wireless tails. From a performance analysis, we show that the proposed scheme has better cost performance than the conventional GSM/IS-41 based location management scheme.
