Abstract
Because Mobile ad hoc networks (MANETs) lack the stationary infrastructures, such as network routers and adopt open wireless medium for communications, attackers can launch eavesdropping attacks, forged attacks, dropping attacks, and collusion attacks. To utilize these attacks, attackers can interrupt communications, send error message to receiver, and analyze the eavesdropping messages to destroy node privacy of sender and receiver. Node privacy contains identity privacy, location privacy, and route anonymity. Therefore, our expected research topic focuses on these attacks to propose the corresponding protocols. In our protocols, attackers cannot obtain any information about sender and receiver from analyzing the eavesdropping messages. Moreover, our protocols can resist dropping attacks and collusion attacks, and the attackers will not participate in route discovery.
