Information-Centric Wireless Networks with Mobile Edge Computing
In order to better accommodate the dramatically increasing demand for data
caching and computing services, storage and computation capabilities should be
endowed to some of the intermediate nodes within the network. In this paper, we
design a novel virtualized heterogeneous networks framework aiming at enabling
content caching and computing. With the virtualization of the whole system, the
communication, computing and caching resources can be shared among all users
associated with different virtual service providers. We formulate the virtual
resource allocation strategy as a joint optimization problem, where the gains
of not only virtualization but also caching and computing are taken into
consideration in the proposed architecture. In addition, a distributed
algorithm based on alternating direction method of multipliers is adopted to
solve the formulated problem, in order to reduce the computational complexity
and signaling overhead. Finally, extensive simulations are presented to show
the effectiveness of the proposed scheme under different system parameters
