Coalitional Game Theory for Cooperative Interference Management in Femtocell Networks

Figure 1

System model illustration. (a) The left part presents a noncooperative approach. Each FUE transmits signals independently and intra-tier interference is caused; (b) the right part presents a cooperative approach. To mitigate the intra-tier interference, FUEs form coalitions dynamically. This paper aims to study this coalition formation problem.
