Swarm Intelligence based Detection of Malicious Beacon Node for Secure Localization in Wireless Sensor Networks
نویسندگان
چکیده
Wireless sensor networks (WS s), made of collection of small, cheap, low power sensors, have diverse applications in several domains of life. Most of their applications demand for spatial position of sensors. Beacon nodes which already know their location are mostly used to help other sensor nodes to locate their position. However localization of sensors in a hostile environment is a crucial issue. The compromised beacon nodes can severely affect the process of localization. The aim of this research is to propose an algorithm to detect malicious beacon nodes based on swarm of intelligent water drops to provide secure localization in wireless senor networks. The paper also critically reviews existing secure localization schemes. __________________________________________________________________________________________
