A Dual Channel Allocation Scheme for WiMedia Networks
نویسندگان
چکیده
In this paper, a Dual Channel Allocation (DCA) Scheme for UWB (Ultra Wide Band) with D-MAC (Distributed Medium Access Control) is proposed. Since distributed characteristic of the WiMedia DMAC supporting DRP (Distributed Reservation Protocol) scheme may cause lots of conflicts, overall performances of the WiMedia D-MAC can be deteriorated. Such DRP termination and renegotiation time delays due to the DRP conflicts can be a critical problem to the mobile devices transceiving realtime QoS traffic streams. Therefore, we propose a DCA mechanism to avoid DRP conflicts by providing a cooperative relay transmission scheme and demonstrate its performance improvements via simulation results.

متن کاملConflict-free Channel Allocation for Wireless Wearable Computer Networks
A Wireless USB cluster tree topology is formed to configure multiple Wearable Computer Networks (WCNs). Basically, a single WCN operates based on WUSB over WBAN protocol. And the host in each WCN takes a role of DRD-host or DRD-device. The WUSB/WBAN flows in a WCN are manipulated in a time period during a WBAN superframe. On the other hand, the DRD flows between WCNs are manipulated in a time p...
