Abstract: Four distributed localization algorithms in wireless sensor networks(WSN) were discussed.Their performances were compared.The energy of WSN was consumed during computation and communication.So the computational cost and communication cost of these algorithms were analysed.Finally,recommendations for future study and possible improvements were put forward.

Key words: localization algorithms, node localization, wireless sensor networks(WSN)
