題目：Coalitional Spectrum Sharing in Cooperative Cognitive Radio Networks
課程大綱:
A coalitional game theoretic approach to resource allocation in a
multi-channel cooperative cognitive radio network with multiple primary
users (PUs) and secondary users (SUs) will be presented. We propose to form
the grand coalition by grouping all PUs and SUs together, where each PU can
lease its spectrum to all SUs in a time-division manner while the SUs in
return assist PUs’ data transmission as relays. We use the solution
concept, namely the core, to analyze stability of the grand coalition, and
the solution concept of Shapley value to fairly divide the payoffs among the
users. Due to the convexity of the proposed game, the Shapley value is shown
to be in the core. The payoff allocations according to the core and the
Shapley value are illustrated by an example, which demonstrates the benefits
of forming the grand coalition as compared with non-coalition and other
coalition schemes.
