Security protocol of wireless sensor networks localization: analysis and performance

Wireless Sensor Network (WSN) is a network that consists of a large number of sensor nodes. In the network, routing protocols are used for communication. Routing protocols discover the appropriate way to transmit data and convoy the routes in the network. A lot of routing techniques have been proposed in WSNs. But the use of these protocols becomes limited without security. It is also a important task to provide secure communication between the nodes. The sensor network application domain continues to increase with the need for an effective security mechanism. The fact that Wireless Sensor Network (WSN) often deal with sensitive data operating in hostile and unexpected environments, makes the concept of security considered essential. However, because of limited resources and low computing capacity of a sensor node, the development of a mechanism that ensures security is a real design challenge. In this paper we have tried to propose a new security mechanism dedicated to WSN. Our main objective is to secure the process of transferring data to the base station. The proposed protocol protects transferred data against intruder nodes attacks, using a security mechanism based on the use of control message MAC (Message Authentication Code) for authentication.
