1. A method of relaying distress calls in a mesh network of nodes, the method comprising:
discovering, by a target node of the mesh network, a plurality of neighboring nodes of the target node that each have one or more types of communication capabilities with the target node;
detecting, by the target node, a failure event associated with a resource of the target node; and
broadcasting, by the target node, a distress call indicative of the failure event to the plurality of neighboring nodes of the target node to cause a first node of the plurality of neighboring nodes to redirect the distress call to an egress node of the mesh network, determine a capability of the first node to redirect the distress call to the egress node of the mesh network, and broadcast a message to a second node of the plurality of neighboring nodes to prevent the second node from redirecting the distress call to the egress node of the mesh network.
