Is Deterministic Deployment Worse than Random Deployment for Wireless Sensor Networks
Honghai Zhang,Jennifer C. Hou +1 more
TL;DR: The results show that under most circumstances, grid deployment renders asymptotically lower node density than random deployment, overriding a previous conclusion that grid deployment may render higher nodedensity than random node distributions.
