Abstract
Information is critical, just as assessing the information available is equally important. The need to easily and quickly assess data securely, that could be processed for information as soon as they are available, is what communication engineers work towards every day. This paper is aimed at identifying areas where further work is needed. As such, a proper understanding of WSNs is needed and different definitions were looked at. Review of previous literatures and research were assessed, the characteristics and applications of WSNs were highlighted done. Finally, the design and topology problems that WSNs encounter as well as the advantages and disadvantages were considered. We then concluded that, the gap between technology and application can be bridged, by addressing these difficulties.
