The IETF 6TiSCH working group fosters the adaptation of IPv6-based protocols\ninto Internet of Things by introducing the 6TiSCH Operation Sublayer (6top).\nThe 6TiSCH architecture integrates the high reliability and low-energy\nconsumption of IEEE 802.15.4e Time Slotted Channel Hopping (TSCH) with IPv6.\nIEEE 802.15.4e TSCH defines only the communication between nodes through a\nschedule but it does not specify how the resources are allocated for\ncommunication between the nodes in 6TiSCH networks. We propose a distributed\nalgorithm for bandwidth allocation, called Local Voting, that adapts the\nschedule to the network conditions. The algorithm tries to equalize the link\nload (defined as the ratio of the queue length plus the new packet arrivals,\nover the number of allocated cells) through cell reallocation by calculating\nthe number of cells to be added or released by 6top. Simulation results show\nthat equalizing the load throughout 6TiSCH network provides better fairness in\nterms of load, reduces the queue sizes and packets reach the root faster\ncompared to representative algorithms from the literature. Local Voting\ncombines good delay performance and energy efficiency that are crucial features\nfor Industrial Internet-of-Things applications.\n
