“…Similar to (Chu & Ganz, 2004), a separate signaling channel is needed for exchanging a node's state information with its direct neighbors. (Broutis et al, 2007) and (Benedetto et al, 2005) outlined a multi-channel MAC in which communication between two nodes takes place on orthogonal channels. The complexity and overheads incurred by such a MAC protocol are higher than single-channel MAC protocols.…”

Abstract-For impulse-radio ultra-wide band (IR-UWB) networks without global synchronization, the first step for correct packet reception is packet detection and timing acquisition: Before recovering the payload of the packet, the destination must detect that the packet is on the medium and determine when exactly the payload begins. Packet detection and timing acquisition rely on the presence of an acquisition preamble at the beginning of each packet. How this preamble is chosen is a network design issue and it may have quite an impact on the network performance. A simple design choice of the network is to use a common acquisition preamble for the whole network. A second design choice is to use an acquisition preamble that is private to each destination. The throughput with the latter choice is likely to be much higher, albeit at the cost of learning the private acquisition preamble of a destination. In this paper, we evaluate how using a common or private acquisition preambles affects the network throughput. Our analysis is based on analytical modeling and simulations. Using our analytical model, we show that a private acquisition preamble yields a tremendous increase in throughput compared to a common acquisition preamble. The throughput difference grows with the number of concurrent transmitters and interferers. This result is confirmed by simulations. Furthermore, additional simulations on multi-hop topologies with TCP flows demonstrate that a network using private acquisition preambles has a stable throughput. On the contrary, using a common acquisition preamble exhibits the presence of a compounding effect similar to the exposed terminal issue in IEEE 802.11 networks: the throughput is severely degraded and complete flow starvation may occur.

“…A key ingredient for the operation of such networks is packet detection and timing acquisition. In networks such as 802.15.4a, or with MAC protocols for impulse-radio ultra-wide band (IR-UWB) networks like DCC-MAC [1] or UWB 2 [2], packet detection and timing acquisition relies on the presence of an acquisition sequence (or acquisition preamble) at the beginning of each packet. In such cases, there is no global synchronization in the network and timing acquisition is performed on a per packet basis.…”

Packet detection and timing acquisition for IR-UWB networks such as 802.15.4a relies on the presence of an acquisition sequence (or preamble) at the beginning of each packet. A simple network design choice is to use a common acquisition sequence for the whole network. A second design choice is to use an acquisition sequence private to destinations. It potentially yields a larger network throughput, but requires additional complexity for sources to learn the acquisition sequence of their destination.In this paper, we evaluate the effect of a common or private acquisition sequence on the network throughput. Our analysis is based on analytical modeling and simulations. We show that a private acquisition sequence yields a substantial increase in throughput. The throughput difference grows with the number of concurrent transmitters and interferers. We also show the presence of a compounding effect similar to the exposed terminal issue in 802.11 networks.
