The Wireless Smart Utility Network (Wi-SUN) Alliance promotes interoperability for large scale wireless mesh networks (WMNs). Such Low-Power and Lossy Networks (LLNs) are widely used in industrial Internet of Things (IoT) settings. In order to improve throughput in node-to-node (N2N) communications for Wi-SUN based wireless nodes, techniques are presented herein that support the addition of a Block Acknowledgement (BA) mechanism to the Wi-SUN protocol. Such a mechanism may, among other things, eliminate a significant acknowledgement (ACK) confirmation overhead when a pair of nodes are using an Extended Directional Frame Exchange (EDFE) mode or an Adaptive Modulation (AM) mode to overcome radio interference.
