Part of the growing IoT scene is low-power, long range communication. LoRa is a popular and growing technology designed for this market segment. Low-power networks typically use very constrained devices, with a limited, battery powered power supply.
A recent development is the availability of LoRa in the 2.4 GHz frequency band. This offers the possibility of higher data rates at a shorter but still a significant range as compared to short range solutions at 2,4 GHz..

Research towards more optimized protocols for LoRa is a very active topic. In particular, the multihop LoRa solutions as compared to the traditional single hop star based solution is under investigation by many research groups in the world. We contribute by proposing routing protocols and improved Medium Access Control to improve reliability and extend and battery life. The focus will be on Time Slotted Channel Hopping, a synchronized protocol already used in several communication standards (e.g. IEEE 802.15.4).

As thesis you would do a thorough performance evaluation of TSCH for 2.4 GHz LoRa using a network evaluation setup designed previously.
