Security in Wireless Sensor Networks
It addresses security vulnerabilities in wireless sensor networks for applications ranging from home use to tactical battlegrounds, but is incremental as it reviews existing state-of-the-art technologies.
This chapter discusses security threats in wireless sensor networks across different layers of the communication protocol stack and outlines possible countermeasures, without presenting new experimental results or specific numerical improvements.
Wireless sensor networks have attracted a lot of interest over the last decade in wireless and mobile computing research community. Applications of these networks are numerous and growing, which range from indoor deployment scenarios in the home and office to outdoor deployment in adversary's territory in a tactical battleground. However, due to distributed nature and their deployment in remote areas, these networks are vulnerable to numerous security threats that can adversely affect their performance. This chapter provides a comprehensive discussion on the state of the art in security technologies for wireless sensor networks. It identifies various possible attacks at different layers of the communication protocol stack in a typical sensor network and their possible countermeasures. A brief discussion on the future direction of research in WSN security is also included.
