Capacity of ad hoc networks with line topology based on UWB and WLAN technologies

Abstract

In this paper a systematic model is used to find a closed-form formula for the channel capacity of ad hoc networks with line topology based on Ultra-Wideband (UWB) and Wireless Local Area Network (WLAN) technologies. As a result, it has been found that the interference level in this network topology is upper bounded and a formula to compute this limit is provided. Based on our computations, it is shown that UWB ad hoc networks have much larger channel capacity than WLAN ad hoc networks. With UWB technology the maximum throughput per node is limited by the transmission bit rate while it is limited by the low channel capacity when WLAN technology is used. As a minor advantage of our findings, a clue about routing algorithm optimization is also given.
