Effects of Power Conservation, Wireless Coverage and Cooperation on Data Dissemination Among Mobile Devices
This paper presents 7DS, a novel peer-to-peer data sharing system. 7DS is architecture, a set of protocols and an implementation enabling the exchange of data among peers that are not necessarily connected to the Internet. Peers can be either mobile or stationary. It anticipates the information needs of users and fulfills them by searching for information among peers. The authors evaluate via extensive simulations the effectiveness of their system for data dissemination among mobile devices with a large number of user mobility scenarios. They model several general data dissemination approaches and investigate the effect of the wireless coverage range, 7DS host density, query interval and cooperation strategy among the mobile hosts.
