Abstract: On the requirement of multiple wireless coverage in some hot applications like indoor positioning and navigation, multipath routing etc., this paper presented a K coverage placement scheme based on an improved Artificial FishSwarm Algorithm (AFSA). A simple obstacle interference describing model was also designed to make our simulation scenario closer to a real one. The simulative results showed that our method could obviously reduce the number of signal nodes and their aggregation on the premise of coverage.

Key words: K coverage, AFSA, WiFi
