Abstract

Wireless technologies enable users to retain their Internet access at anywhere and at anytime, without the tangling of wired cables. Users might want to keep enjoying their favor services when they are moving. However, the user mobility would causes longer and longer path to the serving server so that the QoS cannot be guaranteed. In order to maintain better QoS as a user moves, we proposed a novel and efficient cloud service architecture, named dual migration. The dual migration architecture keeps monitor the location of a user and migrates the contents what the user might need onto the closest server for the current location of the user. Therefore, the hop count of the path between a user and the corresponding server is short.
