One of the typical attacks in Wireless Sensor Networks (WSN), is setting up the wrong route with using a wormhole. The wormhole attack, which is accomplished by selectively relaying packets between adversaries, can ruin the routing and communication of the network without compromising any legitimate nodes. To overcome this threat, there are a few countermeasures against the wormhole attack in WSN. The WODEM (WOrmhole attack DEfense Mechanism) can detect and counter any wormhole attacks. In this scheme, the WODEM can detect and counter wormhole attacks by comparing hop count with the pre-determined initial TTL (Time To Live). The selection of the initial TTL is important since it can provide a tradeoff between the detection ability ratio and the energy consumption. In this paper, we propose a fuzzy rule-based system that can conserve energy for determining the TTL, while it provides a sufficient detection ratio for a wormhole attack.
