4.2  Idea and Concept Analysis

The email system is based on store and forward operation. This operation is matched with the DTN system operation where it needs storage to store a data from the sender before it forwarded to a receiver. The native DTN protocol is much complicated for the average user. The DTN system is mostly Linux based. Average user mostly not familiar with command line and DTN Endpoint ID. TCP/IP email implementation based on DTN concept is much convenient for the average user. The usage is much familiar since it uses native TCP/IP approach for the system. Average users mostly familiar with Windows operating system and this approach maintain the TCP/IP Endpoint ID.

Offline Gmail provides the ability for the user to read and manage their email in an offline environment. But, it is still required each user to move their device to the internet connected area for the pending email being sent, receive and synchronize. The advantage for this thesis work is there is only one device need to move in between terminal location to establish a network. The user can read, send and manage their account normally at each terminal location. The updated data such as new email will be pending in the local mail server until that data is collected by the infomediary device and transferred to the internet connected mail server.
