A novel cost-effective and high-speed location tracking scheme for overlay macrocell-femtocell network

In this paper mobile cloud computing based an innovative location tracking strategy is proposed for overlay macrocell-femtocell based network. In the proposed approach a database is maintained in cloud for each macrocell base station to notify the presence of each user within the macrocell or femtocell. The recently visited femtocell IDs are also stored in the database. By maintaining the recently visited femtocell IDs by a user in the database, the paging cost and delay are reduced to 37.07-41.99% and 27.69-42.07% respectively than previous location tracking method for overlay macrocell-femtocell network.
