Time-variant chemical plume tracing inspired by the silk moth

Chemical plume tracing (CPT) is important in search and rescue operations, especially when it involves release of chemical particles into the environment. This report proposes the novel direction for bio-inspired CPT algorithms. The efficiency of biological systems in performing olfaction as natural instincts such as foraging, mating and homing is indisputable. Large number of bio-inspired CPT solutions are proposed by previous studies. However, the results suggest further improvement is desired for these algorithms. In the recent studies, locomotion of the silk moth is measured and analyzed to propose behavior variation in the time domain, which is consistent with nonlinearity of biological systems. This motivates further interest in identifying time-variant CPT behavior as the solution for complex olfactory problem.
