Node Duplication Attacks could directly damage sensor nodes, and have strong destruction to seriously impact on Wireless Sensor Networks. Against such attacks, this paper presents an improved detection method of node duplication attacks. The network is organized into clusters based on the LEACH algorithm. The level of trust is determined regularly by(More)
This paper analyzes the DV-HOP algorithm which is a range-free localization algorithm. We improve this algorithm by revising the hop-size. In our method, uniform distribution model and secondary reference nodes are introduced to localize the unknown nodes. In addition, the hop-size of the nearest hop is used during the estimation of the distances between(More)
