GA-Based Green SFN Planning for DTMB

This paper proposed an approach based on genetic algorithm (GA) to deploy green single frequency network (SFN) for digital terrestrial television multimedia broadcasting (DTMB). The network optimization goal is to achieve energy efficiency, low cost, low carbon and low exposure to radiation, which caters to the sustainable development strategy. The method is applied over a real area of China, which is described by a digital terrain model (DTM) with the resolution of 20m. In order to show the validity of green deployment, optimization results of three other planning strategies are also presented. Comparisons between optimization results of the four planning strategies show that green deployment strategy can achieve energy consumption savings and low exposure to radiation. Energy consumption savings lead to CO2 reductions and cost savings.
