Systems(TC6).PreviouseventswereheldinParis(France)in2000,Pisa(Italy)
in 2002, Athens (Greece) in 2004, Waterloo (Canada) in 2005, and Coimbra
(Portugal) in 2006.
Networking 2007brought together active and proficient members of the net-
workingcommunity,fromboth academiaandindustry, thus contributing to sci-
entific, strategic, and practical advances in the broad and fast-evolving field of
communications. The conference comprised highly technical sessions organized
thematically, keynote talks, tutorials offered by experts, as well as workshops
andpaneldiscussionsontopicalthemes.Plenarysessionswithkeynotespeeches
opened the daily sessions, covering the three main tracks of the conference.
The Networking 2007 call for papers attracted 440 submissions from 40 dif-

and 27 posters, organized into 24 regular sessions and 1 poster session, made
upthe Networking2007maintechnicalprogram,whichcoverednext-generation
networks:contentdistribution,qualityofservice,topologydesign,routing,buffer
management,opticalnetworks,TCP,security,networkmeasurement;adhocand
sensor networks: connectivity and coverage, scheduling and resource allocation,
mobility and location, routing, and key management; wireless networks: mesh
networks,mobility,TCP,MACperformance,schedulingandresourceallocation.
Thetechnicalprogramwascomplementedbythreekeynotespeeches:“Look-
ing into the Future: Grand Challenges for Wireless Networks,” by Ness Shroff
(Purdue University); “Key Technologies and Architectures for Next-Generation
Networks,”by KrishanSabnani(Bell Labs); and“UrbanMesh Networks:Com-
ing Soon to a City Near You,” by Ed Knightly (Rice University).
In addition to the main technical program,the day preceding the conference
wasdedicatedto three excellenttutorialson“AnIntroductionto NetworkCod-
ing,”byMurielMedard(MIT),“CognitiveRadioNetworks,”byIanF.Akyildiz
(Georgia Institute of Technology), and “WiMAX: Technology for Broadband
Wireless Internet and QoS DrivenRouting: Theoreticaland ExperimentalCon-
siderations,” by Shailender Timiri and Shantidev Mohanty (Intel Corporation).
