on “ 5 G Workshop on Networks , Services and Applications ”

The first joint workshop between Center for TeleInFrastruktur (CTIF), Denmark and Center for Wireless Innovation (CWI), Norway, was held in Aalborg, Denmark on October 8, 2009, focusing on yet undefined term, ‘5G mobile networks’. The fifth generation mobile networks will bring unlimited wireless world interconnection, convergence, and cooperation (geographically including cities, countries, continents, and finally, the whole world), together with a large variety of multimedia services at very high data rates. The objective of the event was to promote the convergence of interest with industrial commitment and leadership in determining strategic research agendas for 5G networks. This Special Issue features eleven selected papers based on networks, services and applications aspects of 5G. The first paper, “Location-Aware Mobile Intrusion Detection with Enhanced Privacy in a 5G Context” by Nils Ulltveit-Moe, Vladimir A., Oleshchuk and Geir M. Køien, presents location aware mobile intrusion prevention system architecture. This solution is envisaged in a future 5G network with increased but varying bandwidth and an evolved threat picture compared to what mobile devices typically experience today. The second paper, “Cooperative MAC Design in Multi-hop Wireless Networks, Part I: When Source and Destination are within the Transmission Range of Each Other” by Xin He and Frank Y. Li, proposes ARQ medium access protocol which addresses various aspects of cooperative communications in a distributed wireless network. The focus is on multi-hop, cooperative, ad-hoc networking independent of any future network features. The third paper, “Cooperative MAC Design in Multi-hop Wireless Networks—Part II: When Source and Destination are Two-hops away from Each Other” by Hongzhi Jiao and Frank Y. Li, proposes a novel MAC protocol which enables two-hop cooperative
