Abstract

Broadband Wireless Access (BWA) has been serving great satisfaction of its users. The WiMAX technology is ideal for the challenges related with earlier versions of wired and wireless access networks. IEEE 802.16 working group standardizes PHY layer and MAC layer only. The most challenging tasks in WIMAX networks are Hidden delay such as Handoff delay and network selection delay, and also Packet loss, Signaling overhead and Average serving rate. The two-tiered mobility management defined in WiMAX can potentially minimize handoff delay and packet loss, but it leads to another problem such as Gateway relocation. In this paper, we propose Gateway Relocation Request Control (GRRC), which combines ASNGW relocation and RC algorithm to maximize system capacity. The proposed system can reduce the average signaling overhead and signal traffic and also increases the average serving rate by solving the ASNGW relocation problem which effectively minimizes the hidden delay. In existing techniques we can’t predict the Main Station (MS) position instead it searches the Base Station(BS)which is nearer to the MS. In this paper we predict the MS position for the improvement of better hidden delay which includes Handoff Delay and Network Selection delay.
