Abstract

We investigate in this paper the resource allocation in wireless multi-hop network and we propose a cross layer based scheduling that takes into account the efficiency of advanced (smart) antenna techniques to increase network capacity by maximizing the number of concurrent transmissions without increasing interference. The proposed algorithm is applied to a WiMAX multi-hop network simulated using OPNET. The simulation results show the capability to dynamically adapt routing decision and scheduling according to the physical layer feedback while satisfying QoS criteria, in addition to a fair distribution of network traffic over whole links among nodes.
