Optimal Association Strategy of Multi-Gateway Wireless Sensor Networks Against Smart Jammers

The Internet of Things (IoT) immensely benefits from wireless sensor networks (WSNs). Unfortunately, WSNs, by virtue being low-power, are vulnerable to physical jamming attacks. This letter focuses on WSNs with multiple gateways where potentially many sensors under the attack a smart jammer. jammer can observe communication links and selectively jam transmission some such that throughput WSN is minimized. proposed defense method develop gateway selection sensors’ associations policy aware jammer’s existence. First, conflict interaction between modeled as Stackelberg game. Then WSN’s strategy, leading Nash equilibrium, derived which both stable optimal. numerical results show compared existing alternative approaches, method, only four gateways, increase more than 200% saves around 30 dB in power consumption.
