Improving channel assignment in wireless mesh network with linear programming
Changsheng Yin, Ruopeng Yang, Wei Zhu · 2016
For multi-radio multi-channel wireless mesh networks (WMNs), the joint channel assignment and routing problem has been shown to be NP-complete. In this paper, we first use a rate-variable model to increase the network through output, which use the physical interference model that can evaluate the capacity more precisely. Then we present a mathematical programming model which allows us to formulate the task of deriving joint channel assignment and routing as an integer linear programming problem. Simulation results show that the proposed approach effectively increases the network through output.
