Abstract: The present disclosure relates to an IP based vehicle network technology. In a method of providing a support for IPv6 networks operating over vehicle-to-everything (V2X) communications, a user equipment (UE) that is mounted on a vehicle to operate based on V2X services communicates with another vehicle through vehicle-to-vehicle (V2V) communication links, generates an available IPv6 address based on a result of communication, and configures an IPv6 address for a multi-hop V2X network when the vehicle moves.

Abstract: A method of preparing layered hydrotalcite-like PVC heat stabilizer from vermiculite is disclosed, including the following steps. Vermiculite is pretreated to prepare nano scale vermiculite flakes. Fluoride, ammonia and water are added, and layered powder layered hydrotalcite-like compound and silica product are prepared through a series of reactions such as ultrasonic dispersion, which realizes the preparation of vermiculite functional products, and is applied to PVC products to improve the heat stability of PVC. The disclosure can directly prepare vermiculite base layered powder products, has the function of stripping layered vermiculite, and has the advantages of low reaction temperature and low energy consumption. In addition, the treatment agent fluoride can be recycled and reused, which is suitable for industrial production.

Abstract: A method for extracting and separating salt alkali from saline alkali soil and soil improvement is disclosed. A foundation pit, square convex edge and cylindrical partition are arranged on a saline alkali land. Nitric or phosphoric acid solution is added to obtain a saline alkali pool. A trench is set around, and/or, a cylinder is set in the center of saline alkali pool. The evaporating material is prepared from vermiculite, laid on plastic wrapping material, and/or added into the cylinder. The salt alkali is precipitated and enriched through natural evaporation. The evaporating material enriched with salt alkali is taken out to be dissolved, separated and washed to obtain saline alkali solution and vermiculite or evaporating material. The vermiculite material is returned for reuse, and the above process is repeated. Alkali solution and intercalation agent are added into saline alkali solution to react and crystallize to obtain functional materials.

Abstract: Provided are an indoor positioning method of a positioning apparatus using a particle filter based on an RSSI includes initializing a particle in a base map corresponding to a target space for positioning, measuring a first distance value between a terminal and a beacon and a second distance value between the particle and the beacon, calculating a weight of the particle by comparing the first distance value and the second distance value, updating a previous weight of the particle based on the weight and resampling the particle, deriving location estimation coordinates of the terminal if the resampling has been performed as many as a given number of times, and moving the particle to a given point in the target space and repeatedly measuring the first distance value and the second distance value again.

Abstract: A method for a first vehicle to perform a neighbor discovery in an IP-based vehicular network is disclosed. The method includes, based on the first vehicle failed in a router discovery for a direct registration with an adjacent road-side unit (RSU), sending one or more first neighbor solicitation (NS) messages to a second vehicle; receiving, from the second vehicle, a first neighbor advertisement (NA) message as a response to the first NS message; and sending, to the second vehicle, a second NS message for registering the second vehicle as a relay vehicle based on the first NA message.

Abstract: The present disclosure provides a method for performing a handoff by a vehicle in an IP-based vehicular network, the method including: transmitting a first router solicitation (RS) message to a first road-side unit (RSU) to access the vehicular network, the first RS message including mobility information of the vehicle; and receiving a first router advertisement (RA) message from the first RSU as a response to the first RS message, the first RA message including a first prefix of the first RSU for configuring an address of the vehicle, wherein the vehicle performs a first address registration procedure based on the first prefix.
