QUORUMS BASED MOBILES LOCATION SCHEME

摘要

Mobile location management is one of the most important problems in the mobile networks systems. Indeed, reducing the search cost increases the update cost and vice versa. That's why, a trade off between the search cost and update cost must be defined. This paper proposes a location management scheme based on quorums. The communication cost is reduced with our method because the information on a mobile location is saved in an efficient manner in a subset of location registers that change with the mobile moves. The proposed algorithm is evaluated in term of total cost of search and update, and is compared to Ihn-Han Bae algorithm.
