Emergence of agent-based referral networks

Abstract
We consider the problem of finding desirable services and sources of information in distributed multiagent systems. Traditional solutions, such as centralized directories, may be inaccurate and may often be unavailable in such settings. Therefore, the only way agents can find the right agents is through referrals. In order to make the referrals effective, the agents must adaptively select the agents with whom they interact. This adaptivity leads to the emergence of referral networks among agents. We study this network experimentally to see the emergence of social structures and the evolution of such structures under different scenarios.
