Minimizing Environmental Electromagnetic Field Pollution Adjusting Transmitter Parameters Using Genetic Algorithm

Paper describes method for finding transmitter parameters (location and power) for optimal electromagnetic radiation distribution in observed area. Constrains are protected areas inside observed area where strength of electric field is limited because of permanent people presence. In observed area one wish to obtain strength of electric field which is higher than lower limit value to cover the area with enough reception signal strength. On the other side electric field inside protected areas has to be lower than prescribed upper limit. Those two conditions are contradictory. In here described investigation genetic algorithm is used to find transmitter parameters (location and power) constrained by above mentioned conditions. Main purpose of investigations is examining applicability of procedure. Initial investigation is limited to rectangular planar observing area with one transmitter and with different formation and size of protected areas (areas in which strength of electric field is limited because of permanent people presence). Procedure has been repeated and results statistically analyzed. Based on those results it can be concluded that procedure is applicable and it is justified to continue investigations for more complex and more realistic situations e.g. more transmitters with directed radiations and for three dimensional spaces.
