TY - JOUR TT - Wireless Sensor Network Security: A Comprehensive Overview AU - Özdemir, Suat PY - 2008 DA - September JF - Politeknik Dergisi PB - Gazi University WT - DergiPark SN - 2147-9429 SP - 207 EP - 214 VL - 11 IS - 3 KW - Güvenlik KW - kablosuz algılayıcı ağları N2 - Wireless sensor networks (WSNs) are shaping many activities in today’s world such as surveillance and tracking. Due to their unattended nature and resource-constrained sensor nodes, however, WSNs are extremely vulnerable against any kind of internal or external security attacks. Considering these vulnerabilities and sensitivity of the data transmitted on WSNs, there is a tremendous need for security mechanisms. Moreover, because of the unique properties of WSNs, these security mechanisms must be developed during system design process. In this paper, we survey the “state-of-the-art” in WSN security, present the obstacles and requirements, and highlight the open research areas that need to be addressed UR - https://dergipark.org.tr/en/pub/politeknik/issue//367229 L1 - https://dergipark.org.tr/en/download/article-file/384705 ER -
