This paper addresses a multi-criteria decision method properly designed to\neffectively evaluate the most performing strategy for multicast content\ndelivery in Long Term Evolution (LTE) and beyond systems. We compared the\nlegacy conservative-based approach with other promising strategies in\nliterature, i.e., opportunistic multicasting and subgroup-based policies\ntailored to exploit different cost functions, such as maximum throughput,\nproportional fairness and the multicast dissatisfaction index (MDI). We provide\na comparison among above schemes in terms of aggregate data rate (ADR),\nfairness and spectral efficiency. We further design a multi-criteria decision\nmaking method, namely TOPSIS, to evaluate through a single mark the overall\nperformance of considered strategies. The obtained results show that the MDI\nsubgrouping strategy represents the most suitable approach for multicast\ncontent delivery as it provides the most promising trade-off between the\nfairness and the throughput achieved by the multicast members.\n
