Energy Efficient Determinism in WSN through Reverse Packet Elimination

In recent years, wired industrial networks has shifted towards Wireless Sensor Networks (WSN). Utilizing WSNs attract interest by various industries as it can provide real time measurements in a cost effective way. Next, with the emerging Industrial Internet of Things (IIoT) WSNs can connect to the Internet. With the creation of Deterministic Networking Group (DetNet), research have been aimed at giving WSNs deterministic capabilities. In this thesis, a novel Reverse Packet Elimination (RPE) algorithm was implemented at IPv6 over the TSCH mode of IEEE 802.15.4e (6TiSCH) stack with intent to increase reliability without increasing energy consumption significantly. RPE was partially investigated analytically, but mainly through the 6TiSCH Simulator. Results of introducing RPE revealed that reliability increased with 10.5%, average latency decreased with 27% and lowest node life was increased with 1.5% over links with 70% quality. However, average energy consumption in the network increased with 19.8% compared to not utilizing packet replication (e.g single point of failure)
