Comparative Analysis of Grid and Tree Topologies in Agriculture WSN with RPL Routing

Agricultural Internet of Things is very dependent on its Wireless Sensor Network (WSN) performance. The Routing Protocol for Low Power and Lossy Network (RPL) is an IPv6-based routing protocol that was developed to provide more addresses and lower power for sensor nodes on WSN. This research compares the performance of grid and tree topologies with RPL routing protocol on Cooja simulator. The parameters evaluated in this study are power consumption, routing metrics, Expected Transmission Count (ETX), throughput, and delay. The result is the performance of the RPL routing protocol with the grid topology has better values than the tree topology in the various parameters tested. In throughput parameters, the grid topology values with 20, 30, and 42 nodes are 901 bps, 722 bps, and 678 bps, better than the tree topology which are 812 bps, 697 bps, and 531 bps.

Automated summary

Agricultural Internet of Things highly relies on the performance of its Wireless Sensor Network (WSN). This study compares the performance of grid and tree topologies with RPL routing protocol on Cooja simulator. The results indicate that the RPL routing protocol with grid topology outperforms the tree topology in various parameters.
