Abstract: Detection of Sybil attack in mobile ad hoc network (MANET) has been a serious issue. A legitimate node, in general, varies its transmission power within a threshold limit. A Sybil attacker can create multiple forged identities having transmission power higher than that of the legitimate nodes. This article focuses on the performance analysis of the Sybil detection technique based on received signal power. Here, we propose the concept of a Sybil detection method for a specific category of Sybil attack where the attacker changes its transmission power along with IDs time to time. To distinguish between a legitimate node and a Sybil node, we calculate received signal power (RSP) of some initially suspected nodes for a number of time instances and draw cubic Bezier curve with these values. By using tangent properties of Bezier curve, we finally trace out Sybil nodes from the suspected nodes and represent them both graphically and mathematically. We analyse the result of each step of the proposed method through simulation and the result shows up to 90% detection rate with only 10% false positive.

Keywords: mobile ad hoc network; MANET; Sybil attack; received signal power; RSP; Bezier curve.
