Abstract: An example apparatus, such as a quorum server of a quorum system, is caused to receive a route information message or duplication thereof from a node of an ad hoc network including a plurality of nodes, with the node having sent or received the route information message during implementation of a routing protocol to determine a route between the nodes, such as according to a gossip algorithm. The apparatus is caused to identify, based on the route information message, nodes intended to also receive the route information message or intended to be part of the determined route. And the apparatus is caused to prepare an instruction message for transmission to one or more of the nodes such that the identified one or more nodes enter or remain in an active mode, and nodes other than the identified one or more of the nodes enter or remain in a power-saving mode.

Abstract: An example apparatus is provided that receives a first message following conclusion of a voice call between a first apparatus and a second apparatus over a network. And in response to the first message, the apparatus obtains a geographic location of at least the first apparatus, and prepares a second message for transmission to the first apparatus. The second message includes a telephone number of a quality server to enable the first apparatus to initiate a voice call to the telephone number to participate in a voice quality test with the quality server, where the voice quality test includes calculation of a score reflecting a quality of the voice call. The apparatus receives the score, and correlates the score with the geographic location of at least the first apparatus and other network parameters obtained during the test to facilitate tuning the network based on the score and the geographic location.
