Activity related to the proposed action:

Giovanni Giambene received the Ph.D. degree in Telecommunications and Informatics 
from the University of Florence, Italy, in 1997. His research activity has been 
carried out within many European projects including:

- COST 227 Project, "Integrated Space/Terrestrial Mobile Networks". 
- SAINT Project, "Satellite Integration in the Future Mobile Network" (RACE 2117).
- COST 252 Project, "Evolution of Satellite Personal Communications from Second to 
Future Generation Systems" 
- "Personalised Access to Local Information and services for tOurists" (PALIO) 
IST Project (IST-20656) within the fifth Research Framework of the European Commission.

In these projects he has focused his activity on resource management problems in both 
terrestrial and satellite mobile systems, including: dynamic channel allocation, 
handoff strategies, performance analysis of mobile communication systems, 
mobility model definitions, traffic scheduling. 

At present, his interests deal with medium access control schemes for the efficient 
integration of multimedia traffics, teletraffic analysis of mobile communication
systems with heterogeneous traffic sources, scheduling algorithms and stability 
analysis of packet access schemes. 

His contribution to this COST initiative is related to the following topics:
- Definition of schemes for the integration of heterogeneous traffic sources 
on the air interface supporting for each of them with specific QoS requirements 
in terms of delay and packet dropping probability;
- Performance and capacity evaluation of both the access network and the core 
network on the basis of suitable traffic models (including short range and 
long range dependent traffic sources).
- Proposal of packet access schemes and related stability analysis for the 
achievement of adaptive protocols maximizing the total throughput.
