An improved hop size estimation for DV-hop localization algorithm in wireless sensor networks

摘要

The sensor localization is an essential function for the wireless sensor networks applications. Based on the characteristics of the DV-hop algorithm, an improved algorithm is proposed for this range-free localization algorithm. The main principle of the proposed algorithm is giving more consideration on network topology properties and making improved hop size estimation through proper tradeoff between network's global and local features. The results of the simulation experiment show its superiority in localization accuracy.
