ALSPR Routing Protocol Based on Improved ADR Protocol

At present, VANET network has become the main network communication system used in the Internet of Vehicles. However, multi hop networks such as ADOV and GPSR in VANET scenarios are only suitable for medium to close communication distance vehicle multi hop protocols. However, the ADR protocol currently applicable to the LORA communication system for long-distance communication and its improved ADR protocol by introducing simplified parameters are only applicable to star network topology. If it is introduced into multi vehicle communication systems in practical applications, it will cause the problem of repeated construction of base stations, greatly increasing material and installation costs. In response to the above issues, this article proposes a multi hop network node selection routing protocol based on Dijkstra algorithm and fuzzy control, namely LSPR protocol, and integrates it with the improved ADR protocol suitable for use in LORA communication systems. By introducing the spread spectrum factor parameter as the input of fuzzy control and introducing it into the Dijkstra algorithm as the judgment basis, the ALSPR algorithm is formed. Compared to other VANET protocols that only replace the LORA communication system, this algorithm can select smaller parameters corresponding to the IP in the weight matrix in the routing vector table as the next hop node, and form a multi hop network with lower link overhead per hop, thus forming a more stable multi hop network system.
