摘要：Establishing correct and efficient routes is an important desi gn issue in mobile ad hoc networks (MANETs), a more challenging goal is to provide secured routing, because ad hoc environment is accessible to both legitimate network users and malicious attackers. Moreover, as the wireless links are highly error prone an d providing security is still a critical task. Generally, security in this type of network is provided by interference of signals, which is not energy efficient. Physical layer security has been considered to provide confidentiality against eavesdropping. Shift difference algorithm has been proposed to transfer the data securel y over the network. It converts the data into noi se for transmission. Network traffic has been reduced, as only intended participants transmit the data. By default network layer secur ity has been provided by encrypti on.
