Reduction of Network Traffic by Using the Peer Cache Mechanism in Co-located Collaborative Web Search on Smartphones

Abstract

As mobile terminals become popular, more people are getting involved with collaboratively searching Web sites in order to achieve a common purpose with others. When performing such a task, we want to save the usage of the Internet traffic as much as possible because the transfer speed of mobile terminals may be limited when the data transfer usage exceeds a certain amount of gigabytes. To reduce the Internet traffic, we build a proxy system with the peer cache mechanism to share the Web contents stored on participating mobile terminals, focusing on the existence of the Web contents which are accessed multiple times from different terminals. Our experimental results reveal that about 20 % of the Internet traffic has been reduced when four people engaged in a collaborative Web search task to find good restaurants for a year-end party.
