Wireless sensor networks (WSNs) have been the recent development in network computing and connectivity. The primary function of WSN is data extraction and transmit the collected data to remote locations. It is having very extensive application such as for monitoring, detection and identification purpose, home automation as well as industrial and healthcare applications. Despite the thriving market there are several challenges to it. For e.g. Node deployment, minimizing the power utilized, bandwidth allocation and coverage. Deployment is vital issue in WSN that affects coverage, connectivity, lifetime and many other factors of WSN. Deployment problem can also be divided into four important categories such as connectivity enhancement, coverage maximization, lifetime optimization and energy efficiency. This paper deals with the objective, strategy and constraints related to WSNs deployment as well as result oriented analysis of various deployment scheme. Also result of various deployment scheme is discussed and provided in tabular form. In conclusion, latest research issues with various possible work are debated.
