| Abstract: |
| Correct node position information is the prerequisite and foundation of many sensor network modules, such as network building and maintenance, monitoring event localization, and target tracking. The node localization process is vulnerable to diverse attacks. In resource-constrained sensor networks, how to securely and effectively locate sensor's coordinates is one of the most challenging security problems. This paper presents various attacks against different node localization systems, analyses the principles, characteristics, and limitations of recent representative secure localization countermeasures. Finally, future research direction is summarized. |
