摘要: Abstract Several applications of Internet Things (IoT) have hundreds nodes, and the expansibility flexibility network can be greatly improved if nodes address themselves automatically dynamically.Existing addressing methods are mainly based on logical relationships between routers. In this paper, automatic geographic-sensing method is studied for end-node (sensor/actuator) without satellite positioning device (such as global system or Beidou system) application IoT deployed in a linear area. The ID determined by its geographical location, which very important location-based routing transmitting strategies. First, sniffer designed to realize an ideal state. Then, according actual scenario, two distributed estimation algorithms received signal strength indicator(RSSI) ranging proposed. Through deployment LoRa-2.4 GHz wireless node testing, results show that when distance greater than twice error, reliability our algorithm guaranteed.
