Energy efficiency based on joint data packet fragmentation and cooperative transmission

Energy efficiency (EE) is a key requirement for the design of short-range communication network. In order to alleviate energy consumption (EC) constraint, a novel layered heterogeneous mobile cloud architecture is proposed in this paper. Based on the proposed layered heterogeneous mobile cloud architecture, we establish an appropriate energy consumption model, and design an energy efficiency scheme based on joint data packet fragmentation and cooperative transmission and analyze the energy efficiency corresponding to different packet sizes and the cloud size. Simulation results show that, when all nodes of the cloud are accessing the same size of data packet fragmentation, the proposed layered heterogeneous mobile cloud architecture can provide significant energy savings. The results provide useful insights into the possible operation of the strategies and show that significant energy consumption reductions are possible.
