Data security in wireless sensor networks via AES algorithm

Wireless sensor networks (WSN) consists of autonomous sensor nodes attached to one or base stations. One of the main goals of wireless sensor networks is to carry reliable information from one node to another node in a network. As Wireless sensor networks continues to grow, they become vulnerable to attacks and hence the need for effective security mechanisms. Identification of suitable cryptography for wireless sensor networks is an important challenge due to limitation of energy, computation capability and storage resources of the sensor nodes. In this paper we have implemented Encryption algorithm AES (Advanced Encryption Standard) to provide sufficient levels of security for protecting the confidentiality of the data in the WSN network.
