Edge Computing
Cloud computing dominated sector of IT in recent time and has twofold value
proposition. Economics is exploited by centralization of scale for lowering marginal cost for
system operations and administration. Organizations could avoid capital expenditure to create
datacenter by consumption of computing resource on internet from provider of large service.
Such considerations led to consolidation of capacity of computing in several larger datacenters
that are spread all over the world. Cloud computing’s proven benefits in economy make this
likely in remaining permanent feature for future landscape of computing (Satyanarayanan, 2017).
However, Nascent applications and technologies for Internet of Things (IoT) and mobile
computing are taking computing close to dispersion. Edge computing is the new paradigm where
substantial storage and computing resources such as cloudlets, fog nodes and micro datacenters
are placed in edge of internet to mobile sensors and devices.
Research interest and industry investment within edge computing grew in past few years.
Radio Applications Cloud Server (RACS) is introduced jointly by IBM and Nokia, which is a
platform of edge computing for 4G networks. As new use cases and applications are explored for
both IoT and mobile computing, virtues for proximity are increasingly becoming apparent. For
physical world, proximity’s importance was never in doubt. In cyber world, seamless
connectivity has lulled in false sense for disregard of physical proximity. Physical proximity is
dependent upon factors like use of networking technologies, user tolerance, application
characteristics and network contention (Pahalovi, et al., 2017). With sufficient investment in
resource and effort, lack of proximity could be masked partially. However, limits are there for
such approach. Need for using strategy of multihop networking for covering hug geographic
