Automated Frequency Distribution, Management & Assignment (AFDMA) in IEEE 802.16

Abstract

Frequency is amongst the most exclusive and most costly resources in wireless communication networks, especially, while considering the demands of Broadband Wireless Access (BWA). In BWA, the management of frequency distribution and its effective utilization is of utmost importance. This research explores possible ways to ensure the most effective allocation of bandwidth resources and their best possible utilization on need basis. The model for static frequency allocation has been optimized and the dynamic frequency management has been calculated while dividing the users in different user classes on the basis of their needs and requirements. The effect of ping-pong handovers has been handled by introducing an inter-base station handshake process, allowing effective management of fast moving users. Automated Frequency Distribution, Management and Assignment (AFDMA) provides maximum bandwidth optimization in order to ensure increased network performance and Quality of Service (QoS).
