Spectrum Sensing Channel Allocation Based on Flower Pollination Algorithm in Cognitive Radio - VANET

Vehicular Ad-hoc Networks (VANETs) are formed through the extemporaneous formation of a wireless network of portable devices in the vehicle area, also known as mobile ad hoc networks (MANET). VANETs are a main element of inventive transport schemes (ITS) and their appearance has delivered traffic safety and additional roadside amenities. The trouble of a shortage of spectrum was developed due to the request for several VANET amenities. To overcome the shortage of spectrum, we use the cognitive radio (CR) technology in VANET has developed a study in recent years. The present spectrum division policies cannot excellently crack difficulties such as network security, Channel allocation, and throughput. In some networks, the cognitive radio VANET is into two types: huge capacity CR-VANET (HCRVANET) and low-capacity CR-VANET (LCRVANET). Make a fresh model for exploiting throughput and plan a channel distribution system based on the Flower pollination algorithm (FPA). To maximize the acceptance probability of safe application service and throughput, we introduce a flower pollination algorithm (FPA). Simulation outcomes verify that the flower pollination algorithm considerably improves the system throughput and the probability of acceptance of safe application services
