Abstract
In a system and method for upgrading software in a wireless mesh network, a first node in the network sends a first multicast request to a plurality of other nodes in the network that are in radio range of the first node. The first multicast request queries whether the other nodes are running a software version older than the software version and device type currently running in the first node. The first node then selects a node to upgrade and sends a request asking if any other nodes have already claimed that node. The first node then updates the nodes only if they have not been claimed for update by another node. In upgrading the claimed nodes, the first node copies to the claimed nodes the software it is currently executing in its internal flash memory thereby creating a clone, and does not store any additional copies of the updated software.
