An efficient optimization model for Fixed Channel Assignment in Wireless Mesh Networks

摘要

Channel Assignment in Wireless Mesh Networks has to ensure connectivity, and guarantee an acceptable throughput. This problem, being NP-hard, must be solved taking into account all the parameters that influence the output of the proposed algorithm. In this paper, we propose an efficient multi-objective optimization model that, simultaneously, optimizes two conflicting objective functions in order to assign channel to radio interfaces subject to connectivity, interference and bandwidth requirements.
