Abstract: This invention provides a system and method implemented in a multi-hop Internet of Things (IoT) network comprising resource-constrained wireless nodes implemented using wireless microcontroller units (MCUs) with integrated IEEE 802.15.4 compliant radio transceivers (4), processing units (1), memory (2), and power sources (6, 7). This invention reduces the number of link-layer ACK transmissions, thereby reducing node energy consumption and minimizing end-to-end packet latency. By leveraging the broadcast nature of link-layer communication, wherein transmitted frames are received using the radio transceiver hardware of neighbouring nodes, and integrating an efficient scheduling mechanism for frame transmissions between the link-layer and adaptive layer of such IoT networking protocol stack executed by the processing units of the nodes, the proposed method significantly enhances network performance in terms of energy consumption, throughput, and end- to-end latency, effectively almost doubling the overall performance metrics of such resource constrained IoT networks. This innovation extends the operational lifetime of IoT networks and also enables the development of more sustainable and efficient resource constrained systems. [figure 1]
