Our recently proposed interference-aware channel segregation based dynamic channel assignment (IACS-DCA) forms a channel reuse pattern with low co-channel interference (CCI) in a distributed manner. In IACS-DCA, each access point (AP) periodically measures the instantaneous received CCI power and computes the average received CCI power on all available channels. Then, the channel-priority table is updated in which the channels are listed in ascending order of the average received CCI power and the best channel having the lowest average received CCI power is assigned to each AP. IACS-DCA is the autonomous-distributed channel assignment scheme based on only the received CCI power information and it has been shown that IACS-DCA forms a stable channel reuse pattern in a static environment. However, the convergence of channel reuse pattern formed by IACS-DCA has been evaluated by computer simulation only. In this paper, we provide game theoretical analysis of the convergence of IACS-DCA. The behavior that each AP selects the channel having the lowest average received CCI power is formulated as the non-cooperative game in strategic form and then, the existence of Nash equilibrium (i.e. convergent point of channel reuse pattern) and convergence performance are discussed. |
