- An End-to-End QoS Framework for 4G Mobile Heterogeneous Environments
- Next Generation Networks NGN will be based upon the "all IP" paradigm. The IP protocol will glue multiple technologies, for both access and core network, in a common and scalable framework that will provide seamless communication mobility not only across those technologies, but also across different network operators. This paper...

- Cross-Layer Optimization of OFDM Systems for 4G Wireless Communications
- This paper advocates cross-layer optimization over the whole ISO/OSI protocol stack. As an example this paper refers to a system using multiple description coding at application layer combined with orthogonal frequency division multiplexing at the link level to provide robustness against hostile wireless channels. In the proposed optimization design negotiation...
