A user-centric ultra-dense network (UUDN) is proposed as one of the promising solutions to provide very high area throughput density and flexible access service for users in the fifth-generation systems. On the one hand, network densification provides opportunities to cooperate among a large number of access points (APs) for serving a given user. On the other hand, the limited radio resources cause...
The WWAN/WLAN two-hop-relay system integrates two types of wireless technologies to improve wireless access throughput and coverage. However, it is unreasonable to assume that all nodes are selfless and willing to relay for other users without an incentive. In this paper, a reputation management framework for Hybrid Wireless Relay Networks is presented. Based on this framework, we show how to collect...
