Network planning and capacity management considering adaptive sectorization in survivable FDMA/CDMA systems

Abstract

In this paper, we investigate the integrated problem of survivable CDMA network planning and management. The problem is formulated as a combinatorial optimization formulation in terms of deploying cost minimization. Solution approach to the development algorithm is Lagrangean relaxation. In experiment results, the proposed algorithm is shown to be more effective and achieves up to 25% reduction on the total deployment cost over a simple algorithm. It also takes around 30% expenses to guarantee survivability.
