Latency minimization is a pivotal aspect in provision of real time services while adhering to Quality of Experience\n(QoE) parameters for assuring spectral efficiency. Edge Cloud Computing, being a potential research dimension in\nthe realm of 5G networks, targets to enhance the network efficiency by harnessing effectiveness of both cloud\ncomputing and mobile devices in user�s proximity. Keeping in view the far ranging impact of Edge Cloud Computing\nin future mobile generations, a comprehensive review of the prevalent Edge Cloud Computing frameworks and\napproaches is presented with a detailed comparison of its classifications through various QoS metrics (pertinent\nto network performance and overheads associated with deployment/migration). Considering the knowledge\naccumulated, procedures analysed and theories discussed, the paper provides a comprehensive overview on\nsate-of-the-art and future research directions for multi-access mobile edge computing.
