Mathematical Modelling and Comparisons of Four Heuristic Optimization Algorithms for WCDMA Radio Network Planning

In order to obtain accurate and reliable network planning and optimization results. The characteristics of WCDMA networks such as power control, soft handover (SHO) and the strong couplings between coverage and capacity have to be modelled accurately. These characteristics lead to unprecedented complexity of WCDMA radio network planning and optimisation that has not been seen in previous cellular networks. In this paper, we will present mathematical models that consider the characteristics of WCDMA radio networks. We will also present and compare the performance of four optimisation algorithms based on meta-heuristics that can be used to find solutions for practical WCDMA radio network planning and optimisation
