Wireless sensor networks need to follow many constraints. This makes the Wireless Sensor Networks (WSN) to face many challenges for communicating with its peers. The Denial of Service (DoS) attack is more common in sensor networks using distributed wireless technology. This attack on sensor networks diminishes the network performance but also affects the reliability of the information. In WSN, detection of as DoS threat is very important than to recover from the attack. The physical layer is the first to be attacked by jammers. In this paper, the DoS attack on the physical layer is analyzed and an extension to the security of the physical layer of the sensor network model using the ant system is proposed.
