There may be many routing algorithms that could be employed in a wireless mesh network. Each algorithm has its own advantages and disadvantages. While proactive routing algorithms can quickly provide up-to-date routing information which helps reduce the routing latency, reactive routing algorithms help reduce routing overhead but instead increase the routing time. On the other hand, some routing algorithms try to provide end-to-end communications despite the high routing overhead and low scalability but some others are designed for the ease of scaling up without providing end-to-end communications. This paper presents a revised HEAT routing algorithm for multi-hop communication in LoRa-based wireless mesh networks expected to provide higher scalability for IoT-based applications. Both software and hardware are also implemented for performance investigation.
