Node Deployment Coverage in Large Wireless Sensor Networks

Currently, wireless sensor network (WSN) is being applied in a lot of different applications. To a large extent the effectiveness of the WSNs depends on the exposure provided by the sensor deployment proposal. There are different deployment demands in different environment. Firstly, we cover the existing deployment method of sensor nodes (SNs) in WSN. We investigate random and deterministic sensor node (SN) deployments for large-scale WSNs in the performance metric coverage. We consider three regular fields circle, rectangle and square for a uniform random, a square grid, a pattern-based Tri-Hexagon Tiling (THT) and Hexagon Tiling (HT) node deployment. Finally, we analyze tradeoffs between these performances metric for each deployment plan to show which approach is preferable under what factors, e.g., the number of SNs.
