Service and network providers must be able to satisfy the demands for new services, improve the quality of service, reduce the cost of network service operations and maintenance, control performance and adapt to user demands. These challenges are so important for the future of our communication environment that it is essential to investigate different approaches for controlling and optimizing network resources.

Network Control and Engineering for QoS, Security and Mobility II addresses the problem of network control and engineering with a focus on control of quality of service, management of security, and supervision of mobility. New trends in these different fields are also investigated.

This volume contains the proceedings of the Second International Conference on NETwork CONtrol and Engineering (NETCON) for Quality of Service, Security and Mobility, which convened in Oman in October 2003. The conference was sponsored by the International Federation for Information Processing (IFIP) and organized by IFIP's Working Groups 6.2 on Network and Internetwork Architecture, 6.6 on Network Management, and 6.7 on Smart Networks.
