DRAMa

Abstract

The Internet of Things is a network of objects, called Things, which can interact with the environment or other Things, with no human intervention. At the same time, multi-agent systems are considered a modern medium of communication and interaction with limited or no human intervention. Hence, combining agent technology with the Internet of Things seems promising. Yet, the open, distributed and heterogeneous environment raises important challenges, such as trustworthiness among the various devices and participants. Hence, distributed reputation models inevitably attract more attention. In this paper we propose DRAMa, a distributed reputation model that provides a novel mechanism, combining reputation with risk and reward. DRAMa attempts to reverse the traditional view of reputation models by involving auctions in the decision making procedures. Finally, an evaluation of the model demonstrates the added value of the approach.
