Article title/year of publication Methodology Advantages Disadvantages
F-ANT: an effective routing protocol for ant colony optimization based on fuzzy logic in the vehicular ad hoc network (2016) The improved ant algorithms and fuzzy logic findings regarding the bandwidth, received signal strength, and congestion to find the most efficient route High data packet delivery rates, low end-to-end delay The high overhead of the ant colony algorithm and the lack of development in the highway scenario
An adaptive geographic routing protocol based on quality of transmission in urban VANETs (2018) The use of quality standards that combines connections and packet delivery rates will monitor the performance of each section of the road so that each section can be dynamically selected to encompass the best route High rate of transfer and delivery rate of data packets Occurrence of local maximizations. Due to the use of the greedy forward, the strategy used to counteract local maximizations increases the end-to-end delay
Probability prediction-based reliable and effective opportunistic routing algorithm for VANETs (2018) A probability prediction algorithm based on the reliability and opportunistic function that predicts the variability of the receiver queue length, the intermediary signal, and noise. The predicted results are applied to determine the usefulness of the relay vehicles in the candidate set. The relay priority of each relay device is determined by its usefulness Reducing the end-to-end delay and delivery rates of high data packets Not considering the influence of parameters such as packet length and transition steps in the results obtained
Adaptive fuzzy multiple attribute decision routing in VANETs (2015) AFMADR is determined in this protocol for any vehicle with these four aspects: distance, direction, road density, and location. A fuzzy score and the characteristics are then allocated to each aspect. Data packets are sent to the vehicles with the highest score. The rate of the end-to-end delay is acceptable Not selecting better carrier nodes for improving packet delivery
