Data dissemination concept attracts increasing attention, since the spreading of digital information becomes of paramount importance. Such information could be multimedia files or continuous streaming segmented into packets to be shared properly among the interested nodes. In this paper, the authors propose game theoretic Medium Access Control (MAC) strategies for data dissemination scenarios. In particular, they use energy-based utility functions that inherently imply power-awareness, while they consider network coding techniques to eliminate the necessity of exchanging acknowledgement control packets. Simulation results show that their proposed strategies enhance the energy efficiency of the system and reduce the dissemination completion time compared to an optimized standard protocol.
