Abstract (Summary)

Wireless networks are becoming increasingly popular over the last two decades, and there is no doubt this trend will continue. The key advantage of wireless networks is that they utilize radio waves to transmit information over the air, hence allowing related devices to communicate in a cordless manner. Nevertheless, the open and shared nature of wireless networks’ communication medium also makes them more vulnerable to various malicious behavior. These malicious behavior include, but are not limited to, jamming, spoofing, and sybil attacks.

Sybil attacks refer to the situation in which malicious users dishonestly generate large numbers of fake identities, and inject them into the network to gain unfair advantage over honest users, or to conduct other hostile activity. Compare with jamming and spoofing attacks, sybil attacks are relatively new, and are not so well-studied, especially in the environment of wireless networks. In this thesis, we focus on the topic of how to effectively thwart sybil attacks in multi-channel wireless networks, and at the same time tolerate other malicious behavior as well.
