Publication Abstract: 

Virtual private network (VPN) is the traditional approach for an end-to-end secure 
connection between two endpoints. Most existing VPN solutions are intended for wired 
networks with high-speed, highly reliable connections. In a mobile environment, these 
network connections are less reliable. This affects traditional VPN performance resulting in 
frequent application failure, data loss, and reduced productivity. Mobile VPN bridges the gap 
between what users and applications expect from a wired network and the realities of mobile 
computing. In this survey, we provide a taxonomy of VPN designs, present a study of existing 
mobile VPN solutions, and highlight the advantages and disadvantages and applications of 

these methods.
