A joint utility scheduler and SDMA Resource Allocation for Mobile WiMAX networks

摘要: In this paper a jointly utility packet scheduler and SDMA-based Dynamic Resource Allocation (DRA) architecture is proposed under the framework of Mobile WiMAX networks. Besides time frequency domains, users can be assigned spatial beams for information transfer, provided degradation in signal quality already slots map resources, with different not affected to point compromising user satisfaction service. Performance evaluation undertaken by means System Level Simulations realistic network layout, fully compatible IEEE802.16e standard. evaluated percentage satisfied given range amount active system. Full Queue traffic mode are performed order estimate gains cell capacity, achieved DRA, over simpler non-SDMA-based DRA.
