Delay constraint energy efficient broadcasting in heterogeneous MRMC wireless networks

In this paper, we investigate the Delay Constraint Minimum Energy Broadcasting (DCMEB) problem in heterogeneous MRMC wireless networks. Especially, we consider heterogeneous radios and channels with different communication ranges and energy consumptions. We present an Energy Efficient Broadcasting (EEB) strategy in this work. EEB utilizes Multi-Dimension Conflict Graph (MDCG) to capture the conflicts among all possible forwarding nodes and channels, and then calculates the schedule to maximize the number of concurrent transmissions in each time slot in a cost effective way without violating the delay constraint. Our evaluation results show that EEB outperforms the state-of-the-art methods in terms of broadcasting energy cost under delay constraint in heterogeneous MRMC networks.
