Since FCC's opening for white space (WS) utilization, database-assisted dynamic spectrum
access (DSA) has become the de facto solution for the realization of dynamic spectrum …

Recently there have been various studies on dynamic spectrum access (DSA) approaches,
eg, opportunistic spectrum access and spectrum auction, to address spectrum scarcity and …

Dynamic spectrum allocation (DSA) based on secondary spectrum market is considered a
promising technology to improve spectrum utilization efficiency and to relieve the wireless …

Dynamic spectrum auction is considered as an effective solution to improve spectrum
utilization efficiency in dynamic spectrum sharing networks because it can provide an …

Licensed spectrum sharing (LSS) is an emerging scheme to improve spectrum efficiency by
authorizing certain secondary spectrum licensees (SSLs) to share spectra with the primary …

In this paper, we investigate the problem of recall mechanism in a dynamic spectrum auction
system. The licensed spectrum holders (SHs) can auction their idle channels to the …

Spectrum under-utilization is one of the bottlenecks of the development of wireless
communication, and dynamic spectrum access (DSA) is envisioned as a novel mechanism …

We consider the design of dynamic spectrum access (DSA) mechanism. Assuming
heterogeneous primary channels with distinct availability statistics unknown to each …

In order to fully utilize spectrum, auction-based dynamic spectrum access has become a
promising approach which allows unlicensed wireless users to lease unused bands from …

Dynamic Spectrum Access (DSA) is emerging as a promising technology to mitigate the
spectrum scarcity caused by static frequency allocations. Despite the clear need for more …
