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.
