Pervasive messaging is the part of pervasive computing that enables users to communicate with each other. Many of today’s electronic messaging systems have their own dis-tinct merits and peculiarities. Pervasive messaging will have to shield the user from these differences.

This system can, in fact, mimic any electronic messaging system, thus providing powerful unified messaging
