Presented herein are techniques for reduce the risk of transmitting collision in wireless networks. The techniques presented herein use a deterministic bandwidth allocation strategy for a central device (central node). As a result, each neighbor can leverage its own schedule to transmit packets with low risk of collision. The central device spreads schedules via DODAG Information Object (DIO) messages in its neighborhood, while dynamically adjusting distribution, per round, according to predicted traffic of its neighbors. The portion of downward and guest account is determined from the software-defined networking (SDN) controller. The SDN controller can design appropriated ratio for each central device on-demand and configure them as a policy.
