Abstract
This paper presents a new distributed algorithm that computes a dominating set of size \(\lfloor \frac{(m+2)(n+2)}{5} \rfloor -3\) on an \(m\times n\) grid, \(m,n \ge 8\). This improves upon the previous distributed algorithm of Fata et al. by 4 on the size of the found dominating set. Our result is obtained by exploring new distributed techniques for corner handling. Also, we point out an error in the termination stage of Fata et al.’s algorithm and give a corrected termination method. Our algorithm finds applications in robotics and sensor networks.

Notes
- 1.
Note also that Chang’s constructive method has to choose from five different permutations based on input grid size.
- 2.
We include vertices of super-grid in labelling for the ease of presentation.
