1. A method comprising: transmitting, from a registering monitor service at a first tier of a hierarchical, multi-tier monitoring architecture for a plurality of separate device networks, each device network including a plurality of wireless devices in wireless communications with one another and with a group leader device executing a group leader monitor service at another level of the hierarchical, multi-tier monitoring architecture, a broadcast solicitation message identifying both the registering monitor service and a registered monitor service associated with a second tier of the hierarchical, multi-tier monitoring architecture, wherein the second tier is specified relative to a plurality of available tiers of the hierarchical, multi-tier monitoring architecture, wherein each group leader device is in communications with a local monitor device executing a local monitor service at another level of the hierarchical, multi-tier monitoring architecture and each local monitor device is in communications with a global monitor device executing a global monitor service at another level of the hierarchical, multi-tier monitoring architecture; transmitting, from the registered monitor service, a broadcast advertisement message indicating an identity and availability of the registered monitoring service for registration, the advertisement message including an identification of the registered monitor service at the second tier, wherein the advertising message is sent in response to the solicitation message or independently thereof; transmitting, from the registering monitor service and in response to the advertisement message, a registration message including registration data associated with the registering monitor service; and registering the registering monitor service at the second tier within the hierarchical, multi-tier monitoring architecture, based on the registration data, including storing at least a portion of the registration data at each higher tier of the hierarchical, multi-tier monitoring architecture; and establishing a communications link between the registering monitor service and additional registered monitor services running on devices at the first tier and lower tiers, if any, based on the stored registration data.
1. A method comprising: transmitting, from a registering monitor service at a first tier of a hierarchical, multi-tier monitoring architecture for a plurality of separate device networks, each device network including a plurality of wireless devices in wireless communications with one another and with a group leader device executing a group leader monitor service at another level of the hierarchical, multi-tier monitoring architecture, a broadcast solicitation message identifying both the registering monitor service and a registered monitor service associated with a second tier of the hierarchical, multi-tier monitoring architecture, wherein the second tier is specified relative to a plurality of available tiers of the hierarchical, multi-tier monitoring architecture, wherein each group leader device is in communications with a local monitor device executing a local monitor service at another level of the hierarchical, multi-tier monitoring architecture and each local monitor device is in communications with a global monitor device executing a global monitor service at another level of the hierarchical, multi-tier monitoring architecture; transmitting, from the registered monitor service, a broadcast advertisement message indicating an identity and availability of the registered monitoring service for registration, the advertisement message including an identification of the registered monitor service at the second tier, wherein the advertising message is sent in response to the solicitation message or independently thereof; transmitting, from the registering monitor service and in response to the advertisement message, a registration message including registration data associated with the registering monitor service; and registering the registering monitor service at the second tier within the hierarchical, multi-tier monitoring architecture, based on the registration data, including storing at least a portion of the registration data at each higher tier of the hierarchical, multi-tier monitoring architecture; and establishing a communications link between the registering monitor service and additional registered monitor services running on devices at the first tier and lower tiers, if any, based on the stored registration data. 11. The method of claim 1 wherein transmitting the registration message comprises: storing the registration data using at least one device associated with the registered monitor service.
