Input-oriented CCR DEA Model for Minimum Energy Multicast: Empirical Study of a Computational Method

This paper considers an existing computational method for minimum energy multicast in ad hoc wireless networks and proposes an empirical model that is based on Data Envelopment Analysis (DEA) methodology. The new model using input orientation with constant returns to scale (CRS) assumption is derived based on Economics concept of production function. The new approach provides alternative means of evaluating system performance with multiple inputs and outputs. This type of evaluation using empirical DEA method to study a program provides adequate technical efficiency measurement compared to the effectiveness performance measurement using a computational method. It is found that the proposed model is able to further minimize the transmission energy by the ad hoc wireless networks without altered the output.
