The robot deployment scheme for wireless sensor networks in the concave region

It is an important issue to deploy sensors on the monitor area for wireless sensor networks. There are many researches about this issue, and they address how to achieve efficient coverage. This paper also provides a sensor deployment scheme, but there are some differences between previous researches. The robot deployment scheme is proposed in this paper, and a single robot deploys sensor one by one according the decided x and y coordinates; the first deployed sensor and the last deployed sensor are neighbor. The scheme can be applied to the deployed area with concave boundaries. Once entering the concave region, the robot can deploy sensor efficiently with full coverage, and then leave the concave region from the exit which is next to the entry.
