Dynamic bandwidth control MAC protocol for CWPAN/IEEE 802.11aj networks

In this paper, we propose a dynamic bandwidth control based medium access control (DBC-MAC) protocol for CWPAN/IEEE 802.11aj networks, which consists of operations like network establishment, network termination, channel splitting and channel expansion. The proposed DBC-MAC protocol solves the coexistence problem between CWPAN/IEEE 802.11aj networks and IEEE 802.11ad networks that are operating in the same or overlapping 60 GHz band and also supports the backward compatibility with the legacy IEEE 802.11ad stations. Performance evaluations show that the DBC-MAC protocol under CWPAN/IEEE 802.11aj networks outperforms the fixed channel bandwidth mechanism under IEEE 802.11ad networks for specific performance metrics.
