Patent ID: 11743173

Abstract:
A method for establishing redundant paths between a source node and the destination node, source node and a destination node in a wireless mesh network, said method comprising the steps of establishing, by said source node, a first path between said source node and said destination node, wherein said first path is associated with a first sequence number and comprises one or more first intermediate nodes in said wireless mesh network; determining, by said source node, to establish a second path between said source node and said destination node; transmitting, by said source node, a path request to a plurality of nodes in said wireless mesh network, wherein said path request identifies said destination node and that said requested second path is redundant to said first path; and said path request is transmitted no earlier than a predetermined duration after said first path is established; receiving, by said source node, from said destination node, a path reply that identifies said second path, wherein said second path comprises one or more second intermediate nodes, and wherein said one or more second intermediate are exclusive of said one or more first intermediate nodes. Complimentary methods and devices for establishing redundant paths in a wireless mesh network are also presented herein.
