Abstract:
Low Power Wide area network (LPWAN) technology is being widely adapted
in different Internet of things (IOT) services. Long Range Wide are Network
(LoRaWAN) is most used in private outdoor applications. LPWAN technology works in a star topology which is easy to construct as compared to
complex multi-hop network. Considering LoRaWAN in dense networks, we
have to have an efficient channel access mechanism to improve efficiency and
robustness as compared to old ALOHA protocol. Little work has started to
implement channel mechanisms in this technology, but it is yet to be tested
in multiple devices under the limit of duty cycle. In our work we will develop new method to use channel sense in efficient way to improve channel
efficiency and to reduce the collisions in LoRaWAN.
