This paper proposes a physical identification based trust path routing (PITrust) scheme to enhance the detection capability of Sybil nodes in RPL protocol in wireless IoT networks, and improve the packet delivery ratio.
Routing protocol for low power and lossy networks (RPL) is a popular protocol used in IPv6 based wireless Internet of Things (IoT) networks. Wireless IoT devices using RPL without centralized security management are extremely vulnerable to Sybil attacks, as a malicious node can forge multiple identities and easily conduct denial-of-service (DoS) attacks. Several countermeasures have been investigated to prevent DoS caused by Sybil attacks in RPL, but crucial limitations still remain. In this letter, a physical identification based trust path routing (PITrust) scheme that uses the received signal strength indicator (RSSI) and a centralized trust scheme to improve Sybil node detection is proposed, which is shown to improve the detection rate and packet delivery ratio when compared to other schemes.
