In wireless sensors and actuator networks, different data sources such as sensors are often required to report data to different destinations such as actuators. In this paper, we ask if the destination diversity, presence of multiple destinations, can enable multiple successful receptions when the sensors transmit their distinctly different data packets over a shared wireless channel in a multi-hop mesh network at the same time. To answer this, we present CROWN, a network protocol that exploits the destination diversity, capture effect, and spatially-separated multi-hop paths between source-destination pairs to enable robust, fast, and energy efficient many-to-many communication between sensors and actuators.
