Jamming-based denial of service attacks are a real threat in wireless sensor networks. This paper studies and analyzes the impact of jamming on micaz motes running TinyOS and explores ways to mitigate the impact. Jamming is facilitated by disabling carrier sensing on the jammer nodes. Jamming attack is detected by tracking RSSI and PDR at the receiver. By varying several parameters at the sender such as power level, packet size, distance from the jammer etc., various jamming mitigation methods are explored and the results presented along with theoretical analysis.
