Security Enhancement for Real-Time Routing Protocol in Wireless Sensor Networks
A.A. Ali, Norsheila Fisal · 2008
Wireless sensor network is a wireless ad hoc network that consists of very large number of tiny sensor nodes communicating with each other with limited power and memory constrain. WSN demands real-time routing which requires messages to be delivered within their end-to-end deadlines (packet lifetime). Since many sensor networks will be deployed in critical applications, security is essential. Recently, many real-time routing protocols have been proposed, but none is designed with security as a goal. This paper proposes a novel secure enhancement for real-time routing protocol that provides secure real time data in WSN. The proposed security countermeasures HELLO flooding and selective forwarding attacks. It ensures high packet throughput and minimized power consumption in the present of adversary nodes. The proposed security has been successfully studied through simulation work.
