摘要
This paper studies two NP-hard problems, the maximum bandwidth routing problem (MBRP) and the maximum flow routing problem (MFRP) in multi-hop wireless mesh networks (WMNs) to support diverse Quality-of-Service (QoS). First, upper bounds on their optimal values are derived, and a lower bound is derived on the feasible value obtained for the MBRP. Then, heuristic algorithms for the two problems are proposed. With the upper bound and the lower bound, an approximation ratio for the heuristic algorithm of the MBRP is obtained.
