In contrast to traditional enterprise service-oriented systems, service announcement, storage, and lookup in MANETs is imposed on the network participants itself. Consequently, cooperation among network participants is crucial to allow for a properly working system. In this context, protocolbased reputation methods have been proposed. Though very successful in many cases, those techniques cannot effectively deal with all observable types of misbehavior. In this paper, we propose a general reputation scheme for evaluating cooperativeness according to a higher-level protocol in MANETs. It complements protocol-based reputation mechanisms by monitoring techniques, to evaluate cooperativeness of the network participants based on currently and formerly (message context) overheard messages. We exemplarily describe and simulatively evaluate a trust building mechanism based on context information for the Lanes overlay protocol for service announcement and discovery.
