Network Coding for Ultra Wideband Communication

Network coding is a novel concept in the field of Information theory which is used for obtaining maximum information flow in a network. Network coding has been shown to offer considerable improvements in the throughput of the network. In this paper we explore the use of network coding in a Ultra-Wide Band (UWB) environment. We have analyzed UWB environment for a sensor based network, where the nodes could be stationery or mobile. We have also analyzed the impact of change in path loss exponent on the throughput when network coding is used. In all these cases, we observe a reduction of up to 40 % in the number of transmissions, which leads to significant power saving for these nodes. We also derive mathematical relationship between number of transmissions and the path loss exponent. Key-Words: Network Coding, Ultra Wideband Communications, Path Loss Exponent
