Network Planning for Next-Generation Metropolitan-Area Broadband Access under EPON-WiMAX Integration

Abstract--This paper tackles a fundamental problem of network planning and dimensioning under EPON-WiMAX integration for next-generation wireless metropolitan-area broadband access. Due to the powerful coordination capability of the Optical Line Terminal (OLT), inter-cell collaboration through physical layer cooperative transmission (CT) among the Optical Network Unit-Base Stations (ONU-BSs) can be initiated. In order to achieve the most efficient deployment of network infrastructure and meet the long-term performance requirements, the proposed planning and dimensioning model jointly considers the problems of ONU-BS placement, BS-User (BU) association, and resource breakdown assignment (RBA), which are further formulated into a combinatorial optimization problem. To linearize the problem formulation, an approach based on decomposition and Special Ordered Set of Type 1 (SOS1) remodeling method is developed such that the reformulated problem can simply be solved by CPLEX.
