Types of Coverage in Wireless Sensor Network: A Survey

Coverage in Wireless Sensor Network (WSN) is the most important parameter and acts as the prime parameter in deciding the efficiency of the sensor network deployed. Nodes in a WSN are used for monitoring and controlling the region of interests in which they are deployed. The coverage thus depends on the communicating range of the sensor node. Therefore sensor nodes deployed in the form of a barrier will provide quality coverage by using fewer sensors when compared to full coverage. Covering every point in the region of interest will lead to redundant sensors and therefore increases the overall operating cost of the network. Barrier coverage, on the other hand, needs much fewer sensors without compromising the quality of service. This paper presents the detail about the WSN with its architecture and provide a review of different types of coverage used in WSN and its application briefly.
