Optimization Algorithm of Resource Allocation IEEE802.16m for Mobile WiMAX

Multi user resource allocation is one of the key features towards high speed wireless network based on Orthogonal Frequency Division Multiplexing Access (OFDMA). According to IEEE802.16m (Mobile WiMAX) standard resource allocation problem has to be performed on a frequency and time two-dimensional space with the Physical and logical resource units (PRU and LRU) including Distributed logical resource unit (DRU and CRU) and Contiguous logical resource unit In this paper we analysed the WiMAX frame structure in IEEE802.16m based on the Mobile WiMAX Standard. We apply novel resource allocation algorithm are used for managing two dimensional resources (time and frequency) to maximizing system capacity depending on mobile user’s data rate. This paper proposes a resource allocation algorithm for radio resource allocation in the downlink/uplink cellular networks using Orthogonal Frequency Division Multiple Access of Mobile WiMAX. Radio Resource Management (RRM) is fundamental in cellular networks. Many optimization problems involving allocation strategies of various types of resource appear in RRM. In this paper we determine the Fractional Frequency Reuse (FFR) and analyze the resources in Mobile WiMAX.
