Abstract: WiMedia Alliance, an industry association for supporting ultra-wide band plays a major role in personal area network. It handles high volume of data for multimedia applications such as construction of home networks, establishment of virtual multimedia connectivity for video or audio sharing, etc. Since quality of service has its own impact in wireless networking domain, we tried to investigate the effect of allocating medium access slot by considering mobility and link quality. We also present an optimal utilisation of bandwidth in a highly contented environment along with a suitable mechanism for scheduling of medium access slots in an effective manner. The performance analysis of the proposed algorithm was tested using OmNet++. The results were promising in terms of improvement delay, throughput and packet drop ratio.
