Abstract: This paper presents a kind of centroid locating algorithm based on hop weighted. This algorithm is based exclusively on connectivity and uses hop information as weight factor to calculate the estimated position of unknown nodes, whose hop influences the result of polygon centroid calculation. Simulations demonstrate that this algorithm can reduce the average locating errors and it is fit for mass Wireless Sensor Network(WSN) application.

Key words: Wireless Sensor Network(WSN), centroid locating algorithm, improved centroid locating algorithm
