A Wireless Sensor Network (WSN) is a group of a densely distributed sensor nodes that monitors physical environmental information and send data to one or many Base Stations (BS) through wireless links. Node deployment is a fundamental issue which is to be solved in Wireless Sensor Networks (WSNs). Node deployment can be random or deterministic in nature. A proper node deployment scheme not only reduces the network cost but also increases degree, coverage and lifetime of a WSN with the reduction in delay. In this paper an overview of existing node deployment schemes are discussed then different parameters that enhance the efficiency are also highlighted.
