As wireless technologies are developed so fast, they also need a generation of se-
curity and privacy control techniques. However, the broadcast nature of wireless
communications, wireless device mobility, and resource limitations make security
in wireless networks an especially challenging problem. This chapter will provide
state-of-the-art research results and future trends related to security in wireless net-
works, including 4G network, ad-hoc networks, and sensor network.
