An Optimal CAC Scheme Based on GSMDP Model in Heterogeneous Wireless Networks

Abstract

This paper proposes an optimal CAC scheme in heterogeneous wireless networks called the GSMDP-based CAC (GCAC). Considering the limitations of the traditional Markov decision process for optimal CAC policy, we characterize the CAC problem through a GSMDP formulation. The performance is evaluated via simulation, and the results are compared with conventioinal GC scheme and an optimal CAC schme based on SMDP.
