In current Internet environment, various kinds of applications exist, for example, e-mail, WWW (World-Wide Web), FTP (File Transfer Protocol), streaming audio/video, and VoIP (voice over IP). However, each service has to be accessed with different application programs, and this makes service integration more difficult. Moreover, in client-server architecture widely deployed in these applications, server load is higher since extra processing is needed besides handling excessive client requests, for example, mail filtering or web content filtering. Most importantly, personalization settings for all kinds of services would further increase server load.
Therefore, in this dissertation, a hybrid peer-to-peer architecture for Internet applications is proposed. With the deployment of location service, the current online status, device capabilities and latest location of a mobile node can be dynamically determined, for example, the current way of contact for users or the current IP address for resources. We can access a mobile node at any time with any device, and existing Internet applications can be improved by offloading the server. Moreover, personal configurations for each user and resource can be easily implemented for each service, thus achieving better customization for each individual user.
