Enhancing Security for Communication in Wireless Sensor Network

Nowadays, many security application areas such as military applications depend on ad hoc wireless sensor networks are concerned about WSN communication security as well as localization security. However, many algorithms exist to provide security for communication to prevent from malicious node. In hostile environments, these algorithms failed to provide security for communication. In this paper, we present a signature-based node authentication mechanism to provide security to prevent from intrusion in WSNs. We are using DSA for generating and verifying the signature.
