| Summary: | 碩士 === 國立臺灣科技大學 === 資訊工程系 === 96 === Initial work in mobile ad hoc networks routing has considered only the problem of providing efficient route discovery mechanisms, without considering security. Because of this, some attacks can be used to manipulate the routing in mobile ad hoc networks. In recent years, there have been many works focus on secure routing protocols.
Most current proposals focus on data packets and few of papers focus on dropping control packets. But dropping control packets may happen when a selfish node did not forward route request packets for excluding itself from route and malicious node as well. Simply, a malicious node may drop route error packets to cause a denial of service. In this paper, first, we analyze the impact of control packets dropping attacks and provide a secure routing protocol against control packets dropping attacks. The simulation study shows that our solution can mitigate such route misbehavior.
