  We propose in this paper a coinvestment plan between several stakeholders of
different types, namely a physical network owner, operating network nodes, e.g.
a network operator or a tower company, and a set of service providers willing
to use these resources to provide services as video streaming, augmented
reality, autonomous driving assistance, etc. One such scenario is that of
deployment of Edge Computing resources.
  Indeed, although the latter technology is ready, the high Capital Expenditure
(CAPEX) cost of such resources is the barrier to its deployment. For this
reason, a solid economical framework to guide the investment and the returns of
the stakeholders is key to solve this issue. We formalize the coinvestment
framework using coalitional game theory. We provide a solution to calculate how
to divide the profits and costs among the stakeholders, taking into account
their characteristics: traffic load, revenues, utility function. We prove that
it is always possible to form the grand coalition composed of all the
stakeholders, by showing that our game is convex. We derive the payoff of the
stakeholders using the Shapley value concept, and elaborate on some properties
of our game. We show our solution in simulation.
