Dessy: Demonstrating Mobile Search and Synchronization

The storage capacity of smartphones has reached tens of gigabytes, while the search functionality remains simple. We have designed a search and synchronization framework for mobile devices, called Dessy. Dessy has been designed with mobility and device constraints in mind. It requires only MIDP 2.0 Mobile Java with File Connection support, and Java 1.5 on desktop machines. This paper demonstrates the application in practice, using multiple devices and synchronizing files between a desktop computer, a laptop, smartphones, and the Internet. Smartphones and laptops are able to search for files hosted on other devices as well as on the Internet. Unnecessary search operations are avoided using Bloom filters.
