Sensor networks support the collection and transmission of large volume of data from different deployed environments, each sensor captured data from a monitored field and send it to the base station. Node authentication is an important security challenge in wireless sensor network (WSN) and it is the main requirement to check the node authentication of the received data at BS. Authentication process of the node was insured in each sensor node by stored the location information for the neighboring nodes. To ensure the authentication process for all attached node, firstly the BS employ redundant messages to require the location information about each attached node and store it in the database. Each sensor node embeds a unique location information and can use it to verify the node authentication and detect replication attack In this paper, there is three types of devices have been used in building a system that detected any replication node, these devices are an Ultrasonic sensor, Arduino Uno, NodeMCU esp2866.
