abstract：

Self-organized network (SoN) has been considered as an important solution to the increasing demand of mobile traffics, due to its flexibility in spectrum access. In SoNs, the nodes sharing the spectrum are located in a distributed manner, and the radio resource management (RRM) must be performed by individual nodes. Moreover, since the RRM decisions of the nodes affect the performance of each other, distributed RRM methods considering the interactions of nodes are desirable for SoNs. While the rising topics of SoNs such as heterogeneous networks and cognitive radio networks (CRNs) have been intensively studied, this presentation will focus on the capability of self-organizing nodes and distributed strategy adjustment based on stochastic learning methods.

I will start with the underlying mathematics, including the game theory fundamentals and stochastic learning algorithm (SLA) and its convergence property, followed by a survey on CRNs. I will also provide other application examples in this talk. In each example, game theoretical framework is adopted to formulate an RRM problem in distributed networks. The nodes in networks are modeled as self-organized learning automata, which learn proper RRM strategies through individual action-reward history. The convergence of the learning procedure towards the Nash equilibrium (NE) is observed via numerical simulations, and the performance at NE is also evaluated.
