A first device may communicate by joining a wireless mesh network that includes at least one wireless device configured to operate a wireless routing protocol, discovering a group of other wireless devices configured to participate in the wireless mesh network, and accessing an interest metric for a second wireless device in the group of other wireless devices. The interest metric is based in part on a network topology from the wireless mesh network. The interest metric is related to an interest threshold and it is determined whether relating the interest metric to the interest threshold supports enabling messaging communications. If so, messaging communications may be enabled.
