The Security Mechanism for Wireless Sensor Networks

Abstract

In recent years, with advances in microelectronics technology and wireless communication technology which promote the rapid development of low power, low price, multifunction sensor, and it also contributed to the development of wireless sensor networks. Wireless sensor network can be used in military, medical and commercial areas. This paper mainly described the characteristics of wireless sensor networks, security threats in the communication process and analyzed its security needs of taking security mechanisms to ensure the security of wireless communications.
