| Summary: | Wireless communications are becoming an integral part of our daily lives such as
wireless local area networks (WLANs) and wireless sensor networks (WSNs). Since
more and more devices are going wireless today, it is essential that future wireless
technologies can coexist with each other. Ultra wideband (UWB) is a promising
solution to this problem due to can coexist with other wireless devices, make it a
good candidate for short to medium range wireless system such as WSNs. This
research presents the analysis of the IEEE 802.15.4a UWB physical layer (PHY), a
novel short range wireless communication technology, for wireless sensor network
applications. We analysed and compared the performance of the UWB PHY using
the MIXIM framework for a discrete event based simulator called OMNeT++.
Among the objectives of our study is to compare the performances by evaluate the
bit error rate (BER), throughput and impact of Reed Solomon (RS) coding. In this
context, we simulated various types of channels – free space path loss,
Ghassemzadeh statistical indoor channels and IEEE 802.15.4a channel models with a
variety of configurations such as data rate, bandwidth and forward error correction.
An analysis on BER over distances and throughput will be discussed to evaluate the
channels performance. The simulation results can be explored for planning and
deploying IEEE 802.15.4a based sensor networks with specific performance
demands. Besides, specific protocol limitations in real time environment can be
identified and solutions can be suggested. |
