... path). Random Networks. We also test the performance of CSR with random networks. 81 nodes are randomly deployed in the field with transmission range R set to 4. We run the simulation for 100 random ... LCSR via 3D grid and random networks. For grid network, we use a network with 64 nodes in a 4 ×4 ×4 grids and set Tr to 8. For random network, we generate 50 random networks...
