Second system, Unity enables collaborative content downloading between a set
of co-located mobile phone users (peers). Almost all the phones, including feature
phones, have one or more small range radio technologies such as WiFi, Bluetooth, and
NFC. Unity leverages one of the available short range technologies for coordinating
and local sharing of workload parts amongst peers, while each part is downloaded
by individual peer from the Internet using a limited bandwidth cellular connection.
Unity use the Cloud for storing mobility profile of the users, their social network,
and content requests from mobile phones users. The Cloud is used to match content
requests to find people with similar interests and it generates notifications to all
interested mobile phone users when they are in physical proximity.
