Node device obtains from adjacent node device route cost for each route from adjacent node device to each node device that is reachable final destination, calculates route cost of route from node device itself to each node device that is final destination reachable via adjacent node device by integrating calculated link cost and obtained route cost. Node device selects adjacent node device that is transmission destination of data frame on the basis of route cost of route from node device itself to node device that is final destination of data frame when data frame is transmitted."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Route selection method, node device and relay system","description":"Node device calculates reception rate of frames of particular frame type transmitted from adjacent node device, calculates arrival rate of unicast frames on the basis of calculated reception rate and ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9621451","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.
