A timely reference that explores the topic more broadly than other books, thoroughly discussing wireless security issues from physical layer to application layer. With the introduction of third generation wireless networks, wireless LANs, Bluetooth, and sensor networks, wireless computing is expanding rapidly. However, security is a major concern for wide deployments of wireless networks. This book identifies important vulnerabilities in the physical layer, the MAC layer, the IP layer, the transport layer, and the application layer, and offers ways to strengthen security and services throughout.
