تکنیک پیشگیری حمله DoS در شبکه های حسگر بی سیم

Wireless Sensor Networks (WSN) has wide applications in data gathering and data transmission via wireless networks. Due to the weaknesses in the WSN, the sensor nodes are vulnerable to most of the security threats. Denial-of-Service (DoS) attack is most popular attack on these sensor nodes. Some attack prevention techniques must be used against DoS attacks. There are different techniques to prevent DoS attack in wireless sensor network. In this paper, an immune system is proposed for the DoS attack on WSN which will improve the accuracy rate of attack prevention, reduce the false alarm rate and able to recognize different Dos attack.
