The authors study the maximum forwarding capacity for the relay traffic that can be transmitted through a wireless multi-hop network in a single direction. The problem appears as the microscopic level problem in a dense multi-hop network where the routing and forwarding tasks can be considered independently (separation of scales). Ultimately, the problem of finding the maximum forwarding capacity involves solving a max-flow problem in an infinite plane with an infinite dimensional scheduling vector as an additional parameter to be optimized. In this paper, they approximate the infinite network by a finite but large network consisting of nodes distributed as a spatial Poisson process, and give the problem an LP formulation assuming a Boolean interference model.
