Abstract
In today’s high-tech “SMART” world, sensor-based networks are widely used. The main challenge with wireless-based sensor networks is the underneath PHY (physical) layer. In this survey, we have identified core obstacles of wireless sensor network when UWB (Ultra-Wideband) is used at PHY layer. A systematic approach is used to assess the effectiveness of UWB for WSN (Wireless Sensor Network). Multiple information sources (surveys, research papers, articles, books and technical surveys) were consulted. Our aim is to measure the UWB’s effectiveness for WSN and analyze the different obstacles allied with its implementation. Here focusing on the core concerns (e.g., spectrum, interference, and synchronization) we started our research by reviewing existing solutions and end up with our findings of the new theories. Our research concludes that despite all the bottlenecks and challenges, UWB’s efficient capabilities makes it an attractive PHY layer scheme for the WSN, provided we can control interference and energy problems. This survey gives a fresh start to the researchers and prototype designers to understand the technological concerns associated with UWB’s implementation.
