Secure Reputation Update for Target Localization in Wireless Sensor Networks

Wireless Sensor Networks (WSNs) are by its nature more prone to security attacks and data losses. Security and data privacy have become need of the day. The most challenging area in WSNs which needs security is target localization. In addition to this complexity the authors are here concentrating on acoustic sensor nodes which uses Particle Swarm Optimization (PSO) algorithm for Location Estimation. They propose Secure Reputation Update Target Localization (SRUTL) algorithm which addresses target localization and security issues viz., bad-mouth attack, Sybil attack, on-off attack and malicious node attack at different levels of target localization.
