Abstract
This paper presents a new air interface concept for wireless multimedia communications beyond the 3rd generation. The proposed air interface uses the same physical layer as that ofETSI HiperLAN/2 and IEEE 802.11a supporting transmission rate up to 54 Mb/sto form a W-CHAMB (Wireless CHannel-oriented Ad-hoc Multihop Broadband)network. Unlike HiperLAN/2, that is based on a central control, W-CHAMB is a self-organizing network without any central control. The responsibilities of organizing andcontrolling of W-CHAMB are fully distributed among wireless stations themselves.A channel-oriented MAC protocol that is based on the dynamic channel reservation (DCR) is proposed for W-CHAMB.Energy signals (E-signals) are used to realize distributed access priorities of wireless stations, to solve the hidden station problemand to achieve a MAC level acknowledgment (ACK) for a fast ARQ.The multihop traffic performance of IEEE 802.11a and W-CHAMB is intensively evaluated stochastically based on a prototypical implementation of the protocols. The superiority of the multihop traffic performance withW-CHAMB can be seen in comparison withIEEE 802.11a.
