Rateless Erasure Coding for Wireless IoT Networks
Summary
The USPTO has granted patent US12585450B2 to Mitsubishi Electric Research Laboratories, Inc. for a system using rateless erasure coding for multi-hop broadcast transmission in wireless IoT networks. The patent covers a network manager that efficiently delivers firmware/software updates to nodes in an IoT network.
What changed
The United States Patent and Trademark Office (USPTO) has issued patent US12585450B2, titled 'Rateless erasure coding for multi-hop broadcast transmission in wireless IoT networks,' to Mitsubishi Electric Research Laboratories, Inc. The patent details a network manager designed for multi-hop wireless IoT networks, which divides firmware/software into source blocks, encodes them, and transmits packets to nodes. It continues broadcasting until a predetermined percentage of nodes receive the program and re-broadcasts missing blocks upon request.
This patent grant introduces a novel method for efficient firmware and software delivery in wireless IoT environments. While not imposing direct compliance obligations on other entities, it represents a technological advancement that may influence future product development and standards in the IoT sector. Companies involved in wireless IoT device manufacturing or network management should be aware of this patented technology, particularly concerning its implications for data transmission efficiency and reliability in multi-hop networks.

Abstract
A network manager for delivering a firmware/software program to multi-mode nodes and single-mode nodes arranged in a multi-hop wireless IoT network. The network manager includes a transceiver configured to perform wireless communication by transmitting the encoded packets of the firmware/software program to the first-hop nodes. The network manager divides firmware/software program into source blocks, encodes the source blocks into encoded blocks based on coding scheme, packs the encoded blocks into encoded packets, and transmits the encoded packets to the first-hop nodes. The first-hop nodes may be configured to receive, decode, re-encode and re-transmit the encoded packets. The network manager keeps broadcasting the encoded packets to the first-hop nodes until a predetermined percent of the first-hop nodes receive the firmware/software program. In response to receiving a re-transmission request of missing source blocks of the firmware/software program from the first-hop nodes, the network manager re-broadcasts the missing source blocks.
