Node deployment is a fundamental issue to be solved in wireless sensor network. A proper node deployment can reduce the complexity of problems in WSN as for e.g., routing, data fusion, communication etc. Different node deployment models have been proposed to reduce the complexity. In this paper, the authors will discuss about the three models-Tri-Hexagon-Tiling (THT), Uniform Random and Square Grid. The nature of deployment of sensor nodes depend on the type of sensors, application and the environment where the networks will operate. Deployment of sensor nodes can be random or pre-determined. In random deployment nodes are deployed in a random manner.
