Energy efficient and secure authentication scheme for wireless sensor networks

Abstract

Wireless Sensor Networks (WSN), is a major technology for effective environmental monitoring and many other applications. Many research work has been carried out due to the susceptibility of sensor networks. The nodes in network communicate with other over sparse wireless channels either in single-hop or in a multi-hop style. Wireless system has been built with developed processors and being utilized in various parts of applications and are being collected in a fractious type. Practically it would be very difficult for envisioning the world devoid of wireless networks. The main security threats in WSN are unsecured radio links and compromised sensor nodes. Selective Forwarding attack also called as gray-hole attack is the mostly used security threat. The malicious node stops the selective packets from forwarding it to the next node or it simply drops the packets from them. It causes denial of service for that particular node or a group of node. In warm-hole attack the messages are replayed continuously between the distant nodes leading to hurried exhaustion of their energy resources. Therefore, considering this as the main focus, this research work proposes to evaluate the framework for energy efficient and secured WSN. EERNS_FM protocol is proposed for the energy efficient relay node selection by applying the fuzzy rules the selection of most proficient relay nodes toward the sink is essential to ensure the routes are more efficient. The active relay node is selected based the proposed fuzzy rule for the further transmission process between the nodes. The nodes are categorized depending on the energy consumption by the nodes and route is arranged with low energy consuming nodes which will balance the energy of the entire network to optimize the network resources. newline newline newline
