Using Context Information to Evaluate Cooperativeness

In: The 4th ACM International Workshop on QoS and Security for Wireless and Mobile Networks, pp. 98-105, ACM, New York, ACM.

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, protocol-based 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.
