  In this paper, we propose a bilateral peer-to-peer (P2P) energy trading
scheme for residential prosumers with a simplified entry to the market. We
formulate the market as an assignment game, a special class of coalitional
games. For solving the resulting decision problem, we design a bilateral
negotiation mechanism that enables matched buyer-seller pairs to reach a
consensus on a set of ``stable" and ``fair" trading contracts. The proposed
negotiation process can be executed on possibly time-varying communication
networks with virtually minimal information requirements that in turn preserves
privacy among prosumers. Numerical simulations illustrate the beneficial
features of our P2P market model and negotiation protocol.
