Executive Summary

Wireless sensor networks have gained considerable attention in the past few years. The authors have found application domains in battlefield communication, homeland security, pollution sensing and traffic monitoring. As such, there has been an increasing need to define and develop simulation frameworks for carrying out high-fidelity WSN simulation. In this paper, they identify the threats and vulnerabilities to WSNs and summarize the defense methods based on the networking protocol layer analysis first. Then, they give a holistic overview of security issues. These issues are divided into seven categories: cryptography, key management, attack detections and preventions, secure routing, secure location security, secure data fusion, and other security issues.
