In this paper, the authors consider N ad hoc networks, with nodes randomly and uniformly distributed, coexisting and sharing an unlicensed band. The objective of this paper is the optimization of the transmission probabilities in these networks to maximize the throughput in each network. Throughput in each system is limited by the self interference (the interference inflicted by a network on its own nodes) as well as the interference from the other networks. They consider the coexisting wireless networks being independent and random. Each network uses a random access method with its own transmission attempt probability. They show that the throughput in each network depends on the choice of transmission probabilities of all networks.
