Abstract:

The location information of the sensor node is one of the key technologies in Wireless sensor network(WSN).This paper proposes two improvements based on the DVHOP algorithm: the anchor placement strategy and the Weighted AHS algorithm,named as Weighted DVHOP.A Matlab simulation model based on the Weighted DVHOP is established.The results show that the proposed algorithm improves node location accuracy by more than 10% with same amount of anchor nodes under same radio range condition.

Key words: wireless sensor networks;node localization;anchor
