IEEE 802.15.4e-TSCH MAC Stack Extensions to GNU Radio

In this work we have designed and implemented the IEEE 802.15.4e- TSCH protocol using GNU radio systems. The goal was to create a user configurable tool to test several future applications that might use deterministic MAC protocol. The main blocks that were implemented include: (a) Clear Channel Assessment using energy thresholding (b) Frequency and Channel hopping (c) Frame structure for Enhanced Beacon, Data frame and Enhanced acknowledgment. Results indicate that IEs and their transmission order are satisfied, Channel hopping and TDMA are validated, and interoperability with COTS radio systems performs well. The timeslot for Tx and Rx were implemented to remain within the standard's specification.
