Abstract

Since a transmitter can only be at one location at a time, a jammer must jam in a narrowband fashion in the spatial domain. We propose JIM-Beam, a narrowband jamming-resilient flooding protocol that randomizes the orientation of a node's directional antenna over time. We use ns-2 simulations to show that JIM-Beam provides improvements in packet delivery ratio over flooding naively and flooding using the uncoordinated frequency hopping protocol.
