Coalitional Game Formulation for Multi-channel cooperative in Heterogeneous Cognitive Wireless Networks
Le Anh Tuan, Choong Seon Hong · 2013
This paper concerns about cooperative problem of mobile secondary users in heterogeneous cognitive wireless network with coexist of secondary femtocell networks, a secondary macrocell networks and a primary network. A scheme with cooperative among wireless network systems to improve capacity, reduces interference to primary system, reduces power transmission of secondary users in uplink data transmission. Specifically, our problem is formulated as coalitional game to maximize payoff of whole system. Simulation results show the effectiveness of our proposed scheme. I.
