Integrating Mobility, Quality-of-service and Security in Future Mobile Networks

Abstract

The development and deployment of wireless networks will mean that devices with multiple network interfaces will soon become commonplace. Users will expect to be always connected from anywhere and at any time as connections will be switched to available networks using vertical handover techniques. However, different networks have different qualities-of-service so a Quality-of-Service Framework is needed to help applications and services deal with this new environment. In addition, since these networks must work together, future mobile systems will have an open, instead of the currently closed, architecture. Therefore new mechanisms will be needed to protect users, servers and network infrastructure. This means that future mobile networks will have to integrate communications, mobility, quality-of service and security. Y-Comm is a new architecture that seeks to integrate these key requirements. This papers shows how these requirements are met in the design of this architecture.
