In the context of B3G heterogeneous environment, the convergence and cooperation of different wireless network technologies are inevitable. The concept of Cognitive Pilot Channel (CPC), which is one of the candidate transmission solutions for the dynamic spectrum sharing of network information in the Cognitive Radio (CR) environment, is proposed to provide the user equipments (UEs) with the necessary network information for both the switch-on and the on-going phases. Optimal mesh division problem appears based on the basic assumptions in CPC concept that the geographical region is organized in meshes and the coverage of different Radio Access Technologies (RATs) overlaps with each other. In this paper, a novel optimal mesh division scheme is designed, taking into account both the Global Position System (GPS) localization shift scenario and multi-RATs scenario. Both the error probability and the information loss ratio are investigated and their impacts to the optimal mesh division scheme are studied by using the Analytic Hierarchy Process (AHP) and Grey Relational Analysis (GRA) algorithms. Optimal mesh division scheme is verified by numerous simulation results.
