Abstract

Security issues are always difficult to deal with in mobile ad hoc networks. People have seldom studied the costs of those secure schemes respectively and for some secure methods designed and adopted before-time, their effects are often investigated one by one. In fact, when facing certain attacks different methods would response individually and it would result in some waste of resource, which may be worthless from the viewpoint of whole network. Making use of the cost management idea, we analyze the costs of secure methods in mobile ad hoc networks and introduce a secure framework. Under the framework not only the network systems own tasks can be finished in time but also the whole network’s security costs can be decreased. We discuss the process of security costs computation at each mobile node and in certain nodes groups. We then exemplify the DoS attacks and costs computation among defense methods. The results show that more secure environment can be achieved based on the framework in mobile ad hoc networks.
