WebFeb 16, 2024 · Density reachability is the transitive closure of direct density reachability, and this connection is asymmetric. There is only core objects are mutually density reachable. Density connectivity is a symmetric relation. A density-based cluster is a group of density-connected objects that is maximal concerning density-reachability. WebIn simulation, the source nodes of broadcasting packets are selected using partition degree (PD) and average hop to reach the reachable nodes (AHRN) to guarantee a fair comparison. To observe the performance variations according to node density, we vary the variance of the number of neighbor nodes.
