1 Security in Wireless Sensor Networks

Wireless sensor networks, a new generation of real-time embedded systems with limited computational power and memory that has a variety of applications, especially in cases that are not possible using traditional networks. With advances in technology, the ability of the sensor network advances as well. Given that the existing environment is unsecured, wireless connections and nodes have limited abilities and there are internal and external threats and opportunities, an attacker can use a computer system with a high ability to penetrate the network. Therefore, security in wireless sensor networks is a critical challenge. In this paper, the issue of security in wireless sensor networks is discussed
