network depends on deployment of sensors. Deployment can be done either Random deployment or Deterministic deployment. Deterministic deployment of homogenous sensor nodes is impractical in some situations such as dynamic battle regions and hazardous situations. In such situations there is an alternative way to deploy the sensors randomly. Random deployment causes area of intersection in nodes. The techniques are reviewed in this paper that can be implemented to resolve deployment issues. The main objective of this paper is to review the techniques that can maximize the coverage and removes the overlapping area between nodes. Keyword: Deployment, Fuzzy Logic System, Maximum Coverage , Wireless Sensor Network I. INTRODUCTION A wireless sensor network is also called as Actuator network. Wireless sensor network is connection of “nodes” that communicates between a couple to hundred or even thousand nodes , that monitor specified area and communicate the monitored information to sink node. Each such sensor node has typically several parts: a radio transceiver, an electric circuit and energy source or an embedded form of energy harvesting. Fig 1: block diagram of wireless sensor.>
