Method of forwarding a received message in a mesh network comprising a plurality of communicatively interconnected mesh nodes as well as a corresponding mesh node

Abstract:

Embodiments include methods, performed by a first mesh node, of forwarding a received message in a wireless mesh network. Such methods include receiving, from a third mesh node in the wireless mesh network, a message whose destination is a second mesh node in the wireless mesh network. Such methods also including forwarding a plurality of repetitions of the message to the second mesh node. Successive repetitions of the message are separated by respective time delays, which are based on whether the first mesh node has an established friendship relationship with the second mesh node. For example, if the first and second mesh nodes have a friendship relationship, at least three repetitions of the message are forwarded by unicast transmission, and the respective time delays are equal and are between 100-200 .mu.s. Embodiments also include complementary methods performed by a second mesh node, and mesh nodes configured to perform such methods.
