Personal Networking is an emerging concept which combines pervasive computing and strong user focus. The idea is that the user’s personal devices organize themselves in a secure and private personal network transparently of their geographical...
A PN can provide the opportunity to personalize applications, services and the whole networking environment to the current needs of the user, making the security and privacy the key features in the PNs formation.
