Detection of Sybil Attack in Beacon Enabled IEEE802.15.4 Networks

In this paper, we describe a Sybil attack detection algorithm in IEEE 802.15.4 beacon enabled clusters. Our algorithm is based on received signal strength at the cluster coordinator. It considers the multi-path fading and shadowing and uses only two parties to detect the attacks. Using this technique, the detection of sensor displacement attack is also feasible. The results show high accuracy of attack detection and suggest parameter selection values to keep high level of performance. This lightweight scheme suites the IEEE 802.15.4 network nodes which have limitations in terms of battery energy, memory size and CPU speed.
