Gap mechanism for energy efficiency models in wireless multicast networks

This paper presents a gap mechanism for evaluating the performance of three energy minimisation models in wireless multicast networks. The first model is the existing coded packet that is based on simulation technique. The second and the third models are the recently proposed techniques that are based on data envelopment analysis (DEA) methodology. The input-oriented Banker, Chanes and Cooper (BCC) and Chanes, Cooper and Rhodes (CCR) approaches are considered for DEA model development. It is found that the proposed input-oriented BCC and CCR models provide better energy gap in wireless networks compared to the coded packet model.
