IEEE 802.16 mesh does not include support to traffic flows with strict Quality of Service requirements. In this paper, we propose an End-to-end Bandwidth Reservation Protocol (EBRP) in the backhaul of a Wireless Mesh Network using IEEE 802.16 mesh. The distinctive feature of EBRP is that it is carried out at the Medium Access Control (MAC) layer. Therefore, EBRP not only makes the resource reservation process extremely rapid, it also allows the available resources to be allocated efficiently by exploiting technology specific iinformation available at the MAC. We present EBRP as part of a framework which also includes the support for performing distributed Call Admission Control (CAC). Preliminary simulations results obtained with VoIP traffic and nodes arranged in a grid topology are presented to show the effectiveness of EBRP, with ideal CAC computation.

Abstract
IEEE 802.16 mesh does not include support to traffic flows with strict Quality of Service requirements. In this paper, we propose an End-to-end Bandwidth Reservation Protocol (EBRP) in the backhaul of a Wireless Mesh Network using IEEE 802.16 mesh. The distinctive feature of EBRP is that it is carried out at the Medium Access Control (MAC) layer. Therefore, EBRP not only makes the resource reservation process extremely rapid, it also allows the available resources to be allocated efficiently by exploiting technology specific iinformation available at the MAC. We present EBRP as part of a framework which also includes the support for performing distributed Call Admission Control (CAC). Preliminary simulations results obtained with VoIP traffic and nodes arranged in a grid topology are presented to show the effectiveness of EBRP, with ideal CAC computation.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
