The presence server is configured to send an acknowledgment in response to a check-in message. Each of the wireless data communication devices is configured to reset a timer associated with the sending of the check-in messages by it upon (i) communicating, as an intermediate node, a check-in message originating at another node, and (ii) communicating, as an intermediate node, a corresponding acknowledgment originating at the presence server. The presence server is configured to update presence information of wireless data communication device from which a check-in message originates and each intermediate node."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Updating node presence based on communication pathway","description":"A data communications network, for which presence information is maintained for wireless data communication devices forming nodes of the network, includes: a presence server; and a plurality of nodes ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8462662","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
