Beamforming technique is used in IEEE 802.15.3c networks to avoid high propagation attenuation and path loss, and improve the overall system throughput by exploiting spatial channel reuse. In this paper, we introduce the necessity and design challenges of inter-piconet communications. Based on our observation, we propose a joint design of relay selection and scheduling. For relay selection, we define...
The IEEE 802.16 standard is a promising technology for 4G mobile networks. Though supporting versatile service classes, best effort (BE) service class is expected to dominate WiMAX networks, due to operational simplicity. One of bandwidth request mechanisms that subscriber stations (SS) can utilize to issue bandwidth requests (BW-REQ) for BE connections is contention-based random access. An SS starts...
