Abstract
In this paper, we introduces a multi home agent and pointer-based location management scheme. Multi home agent preserves the location information for different wireless technologies (Universal Mobile Telecommunication system, Wireless Local Area Networks) and maintains a cache for the location information of mobile host. In addition, an index based call delivery system has been proposed. The performance comparisons and numerical analysis are helpful to find out the efficiency and effectiveness of the proposed system, with respect to existing location management techniques (single registration scheme, and dual home agent scheme). It has been observed that the registration cost, call setup delay, registration delay and overhead at mobile switching center are reduces in the proposed MHA–PB scheme.
