Honeybees: Combining Replication and Evasion for Mitigating Basestation Jamming in Sensor Networks

By violating MAC-layer protocols, the jamming at-tack aims at blocking successful communication among wireless nodes. Wireless sensor networks (WSNs) are highly vulnerable to jamming because of reliance on shared wireless medium, constrained per-sensor re-sources, and high risk of sensor compromise. More-over, base stations of WSNs are single points of fail-ure and, thus, attractive jamming targets. To tackle base-station jamming, replication of base stations as well as jamming evasion, by relocation to unjammed locations, have been proposed. In this paper, we pro-pose Honeybees, an energy-aware defense framework against base-station jamming attack in WSNs. Honey-bees efficiently combines replication and evasion to al-low WSNs to continue delivering data for a long time during a jamming attack. We present three defense strategies: reactive, proac-tive, and hybrid, in the context of multi-hop WSN de-ployment. Through simulation, we show the interac-tion of these strategies with different attack tactics as well as the effect of system and attack parameters. We found that our honeybees framework struck an energy-efficient balance between replication and evasion that outperformed both separate mechanisms. Specifically, hybrid honeybees outperformed replication and evasion at low and intermediate number of attackers and grace-fully degraded to high attack intensity. 1.
