Abstract: The paper researches positioning algorithms of wireless sensors network and proposes a new positioning algorithm. The basic principle and the implementing approaches of the algorithm are introduced. The algorithm doesn't require any excess hardware and message between nodes is very low. Simulations show that average positioning error less than 21% of nodes' radio range in a scenario where an average connectivity is 8 and anchor nodes is 20.
