摘要：Localization algorithm is an important and challenging topic in Wireless Sensor Networks (WSNs), especially for the applications requiring the accurate position of the sensed information. Various algorithms have been proposed to obtain the location of sensor nodes. However, most of existing location algorithms assumes a non-adversarial environment. The position estimation accuracy decreases drastically when some of the sensor nodes are compromised. In this paper, we develop a secure localization scheme to resist the attack on the DV-Hop scheme, to mitigate the impact of such attacks. In our scheme, the flooding packets in the DV-Hop will be authenticated and the weight of beacon nodes will be used to abate the effect of nodes capture attack. Analysis and simulation results demonstrate that the proposed can not only against nodes compromised attack effectively but also achieve comparable localization performance
