Fully-Redundant Mesh RoutingRedundant routing is a must have in real world RF environments. Conditions change dramatically over time due to weather, new/unknown RF systems, moving equipment and population density. Combine this with the utter unpredictability of node placement, installer practices, and future network expansions or repurposing, and one gets a clear picture of the challenges facing RF reliability. A full mesh topology with automatic node joining and healing lets the network maintain long-term reliability and predictability in spite of these challenges. Fully redundant routing requires both spatial diversity (try a different route) and temporal diversity (try again later). TSMP covers spatial diversity by enabling each node to discover multiple possible parent nodes and then establish links with two or more. Temporal diversity is handled by retry and failover mechanisms. A full mesh network does not rely on special-purpose routers, base stations, or aggregators, and does not require nearly the wireless expertise and installation skill of other solutions. There is no need to survey, engineer and then ultimately overbuild point-to-point connections. As a full mesh is installed, all connected nodes form one giant antenna for other joining nodes. This allows for extremely quick and robust installations. Additionally, should an installed network need to be expanded a full mesh network can gracefully accommodate new nodes by relying on edge nodes to automatically assume routing duties.
