This powerpoint presentation presents a study to allocate sensors throughout a system with the objectives of: detecting contamination events as early as possible; minimizing the affected population; minimizing the contaminated water volume; and, maximizing detection likelihood. Project challenges included: define contamination events - can happen any time at any location, and can happen at one location and multiple locations at the same time; sensor locations - many combinations, and allocate k sensors from n nodes; how many possible contamination events - huge number for a small system, and theoretically infinite; solution space - huge to astronomical combination, e.g. for 1000 nodes to have 5, 10 and 20 sensors, and possible solutions include 8.2x10¹², 2.6x10²³, and 3.4x10⁴¹. Battle of Water Sensors Network (BWSN) is presented, along with BWSN design objectives, formulation, network solutions, network comparisons, and practical tips. Includes tables, figures.
