The Neighbor Discovery Protocol (NDP) is one of the critical research subjects in Wireless Sensor Networks (WSNs) for efficient energy management of sensor nodes. A block design concept can be applied to find a neighbor discovery schedule that guarantees at least one common active slot between any pair of sensor nodes. However, the block design-based solutions in literature are not flexible enough because block design cannot support asymmetric asynchronous operations. In this paper, the authors introduce a new approach for asymmetric asynchronous neighbor discovery protocol that combines two optimal block designs using the OR operation.
