We propose efficient spectrum channel allocation and auction methods for the online wireless channel scheduling. Assume that each user requests for the exclusive usage of a number of wireless channels for a certain time interval. The scheduler has to decide whether to grant its exclusive usage an how much will be charged. To possibly serve users with higher priority, preemptions are allowed with penalties...
In wireless networks, we need to allocate spectrum efficiently. One challenge is that the spectrum usage requests often come in an online fashion. The second challenge is that the secondary users in a cognitive radio network are often selfish and prefer to maximize their own benefits. In this paper, we address these two challenges by proposing TOFU, a semi-truthful online frequency allocation method...
Cognitive networks become hotspot in the field of network research recently. It is considered a valid solution for heterogeneous networks. In this paper, we propose a new architecture of cognitive networks and divide its cognitive capabilities into three sub-layers named access cognitive layer, network cognitive layer and service cognitive layer. The aim of the design is to implement cognitive capabilities...
