Abstract: Various embodiments disclose a method performed by a first node device in a mesh network that includes identifying a plurality of neighbor node devices that have one or more blocks of a dataset; determining quality scores for respective node devices of the plurality of neighbor node devices; selecting, based on the quality scores, a second node device from the plurality of neighbor node devices; and sending, to the second node device, a first request to receive at least one block of the one or more blocks.

Abstract: Various embodiments disclose a method comprising determining, by a first node, a first link latency associated with a second node based on a time period between consecutive slots in a unicast listening schedule for the second node; in response to the first node detecting a failure in transmitting a first frame to the second node, determining, by the first node based on the first link latency, a first backoff time; and in response to determining that the first backoff time has elapsed, retransmitting, by the first node, the first frame to the second node.

Abstract: A method for reprogramming data of a software function executed by an execution core and a security core, the data being present in two physically separate non-volatile memories, each managed by one of the execution or security cores, including the following steps: upon receiving a reprogramming request, a second value is stored in a first Boolean, determining whether the first Boolean is equal to the second value and if a second Boolean is equal to a first value, and if affirmative; an execution core is made to emit at a reinitialization request via a bidirectional communication channel towards a security core and a request to initialize a portion of the first non-volatile memory towards the set of functions for managing the non-volatile memory by an execution core; a second value is stored in the second Boolean; it is determined whether a predetermined reprogramming event has taken place, and if affirmative, the first value is stored in the first Boolean, while keeping the second value in the second Boolean
