As a huge numbers of heterogeneous devices will be connected in social cognitive radio networks (SCRNs), it needs more frequency spectrum. Moreover, dynamic spectrum availability and heterogeneous devices make it more difficult for routing design in SCRNs. Opportunistic routing (OR) can leverage the broadcast nature of wireless channels, and then can enhance network performance. In this work, we propose an energy aware coded OR (ECOR) in SCRNs, which jointly considers energy efficiency and social feature for designing coded OR. In the proposed OR, we exploit a new scheme for candidate selection and use network coding in data transmission between selected nodes in SCRNs. In addition, we propose a game-theoretic approach to decide forwarding candidate set which is based on auction mechanism. The simulation results demonstrate that the ECOR performs better compared with existing routing in SCRNs in terms of hop count and packet delivery ratio.
