Wireless sensor network (WSN) is a wireless network of tiny, low-power nodes deployed in a region to keep track of environmental surroundings and collect data to be processed at a remote base station. Deployment remains one of the greatest challenges in WSN that impacts coverage and connectivity amongst other things. Coverage is one of the important issues in sensor networks, which echoes how well a network is tracked by sensors. This paper studies different deployment schemes which can be used in WSN for maximum coverage. This study also gives a comparison between various deployment schemes along with the number of sensor nodes to be used in each case.
