Access to internet has developed world wide and all the electronic devices are designed with wireless communication interface. Any time people can access internet from anywhere. So the Internet Engineering Task Force introduced the concept of moving network from one place to another. They used Virtual Private Network, but it cannot be used for real-time applications. In this paper, the people can communicate between private network and public network in a secured way using AES algorithm and the movement of network is considered. The Virtual Private Network gateway is used for the secured data transmission. The cost for signalling gets reduced by using this approach. The performance is evaluated using analytical models and simulations.
