This paper investigates the utility maximization problem for the downlink of the multi-interface multichannel wireless mesh network with orthogonal frequency division multiple access. A cross-layer joint power and multiple access control algorithm are proposed. Rosen projection matrix is combined with Solodov projection techniques to build a three-memory gradient Rosen projection method, which is applied to solve this optimization problem. The convergence analysis is given and simulations showdoi:10.1155/2014/352809 pmid:24883384 pmcid:PMC4030496 fatcat:wqplup7xpzaj7pzase3kkftg6q
