Flow Problems in Multi-Interface Networks
By Gianlorenzo D'Angelo, Gabriele Di Stefano, Alfredo Navarra
In heterogeneous networks, devices communicate by means of multiple wired or wireless interfaces. By switching among interfaces or by combining the available ones, each device might establish several connections. A connection may be established when the devices at its endpoints share at least one active interface. In this paper, we consider two fundamental optimization problems. In the first one (Maximum Flow in Multi-Interface Networks, MFMI), we aim to establish the maximal bandwidth that can be guaranteed between two given nodes of the input network. In the second problem (Minimum-Cost Flow in Multi-Interface Networks, (MCFMI), we look for activating the cheapest set of interfaces among a network to guarantee a minimum bandwidth B of communication between two specified nodes.r generation approach and several design/test techniques to improve the detection sensitivity.
