Abstrakt
An important security problem in today's distributed data networks is the prevention of non-cooperative behavior i.e., attacks consisting in the modification of standard node operation to gain unfair advantage over other system nodes. Such a behavior is currently feasible in many types of computer networks whose communication protocols are designed to maximize the network performance assuming full node cooperation. Moreover, it may be relatively easy to avoid detection if the network-wide administrative or punitive mechanisms are insufficient.In this paper we analyze how local watchdog processes located in network nodes can be deployed to detect and counter a non cooperative behavior in self-organizing multihop wireless networks. In addition to theoretical discussion of several possible solutions, we include the results of simulation modeling and practical implementation scenarios conducted in our research testbed for the most promising mechanisms.
