An efficient algorithm to solve base station location and channel assignment problems in a cellular network

Call blockage may incur large losses in areas prone to traffic accidents. We formulate an optimisation problem that chooses base station locations and assign channels to them so as to minimise the overall installation and call blockage costs. Since this problem is a difficult non-linear integer program, we develop an efficient algorithm that finds the optimal solution. The paper features the so-called demand areas that characterise the demand for service of a large number of itinerant cell phone users travelling over a geographic area.
