A remote control scheme for ubiquitous personal computing

Abstract

In the schemes designed for ubiquitous computing remote access to private dato is generally achieved by requiring users to deposit the data on certoin. always-on-line servers in the network infrastructure. However. when the data to be accessed remotely is somewhat sensitive, as implied by many opplications of personal computing, users may prefer to warehouse the data in their residences rather than in somepublicplaces. In this paper, a navel scheme is proposed to realize personal computing ubiquitously by satisfving such demand The proposed scheme employs home-automation techniques to grant properly authenticated users remote access to the dnta stored somewhere offthe i@astructure (e.g., their personal workstations) while avoiding the expense of deploying high-avoilability servers at home. It also provides three kin& of authentication mechanisms and hence allows users to choose among different levels of the tradeoff between security and ubiquity, providing a complete solution for ubiquitous personal computing.

“…The base station is setup such that all essential applications launch themselves automatically on startup. The Serial Forwarder and Base Station software runs upon boot up, the Apache webserver begins serving webpages immediately and users can locate the webpage of the base station by navigating to a dynamic DNS address [8] which detects and updates that address to point to the current IP address obtained by the base station's network interface. MySQL server is installed on the base station to provide a database server for storing motes information (e.g.…”
