ABSTRACT
Wireless sensor networks (WSNs) simplify the collection andanalysis of data frommultiple locations. The self-organization capabilities of wireless sensor networks enable rapid deployment of target tracking and intrusion detection applications in hostile environments. However, sensor networks deployed in adversarial environments must be fortified against attacks. This chapter examines the threats against WSNs and surveys countermeasures that protect their communications with origin integrity and data integrity. This chapter also provides an analytical framework to solve the security problem in WSNs deployed for surveillance and target tracking.
