Wireless sensor network (WSN) as an emerging technology has eased life via its numerous applications. Research interests
and attention have been drawn to WSN in the last decades. Exploring and finding better ways of improving the existing technology has
been a continuous process. This paper presents a review on wireless sensor networks, covering WSN architecture to characteristics,
advantages, several challenging issues of WSN, network topology and IEEE standards for physical layer of WSN.

WSNs in addition to being an emerging technology are
becoming very relevant in the communication industry.
Irrespective of the challenges and short falls, they are
providing services that are essential in most common and
everyday applications. Key features of reliability, security,
energy efficiency, compatibility, etc. are always going to
be faced but with research and advance in technology, the
challenges can be met.
