Vehicular adhoc networks are becoming a popular and promising technology in the modern intelligent transportation world. As per safety applications of VANETs any information circulating through network can be life crucial. So integrity is critical need. The mobility nodes volatile nature connections has made VANET vulnerable to many security threats. One major attack that exhausts by illegitimately using all its resources DDOS attack. In this type an attacker fakes multiple identities i-e uses spoofed IP addresses exhaust bogus messages making it deny cater legitimate requests for services. before proper deployment practically needs must met. paper detection then prevention scheme proposed. basic principle keeping check on number packets being injected into network. proposed structure causes almost no overhead resources.

The purpose of this study lies in developing a comparison neural network-based models for vehicular congestion prediction, with the aim improving urban mobility and mitigating negative effects associated traffic, such as accidents congestion. This research focuses on evaluating effectiveness different network architectures, specifically Transformer LSTM, order to achieve accurate reliable predictions To carry out research, rigorous methodology was employed that included systematic literature review based PRISMA methodology, which allowed identification synthesis most relevant advances field. Likewise, Design Science Research (DSR) applied guide development validation models, CRISP-DM (Cross-Industry Standard Process Data Mining) used structure process, from understanding problem implementing solutions. dataset key variables related vehicle speed, flow, weather conditions. These were processed normalized train evaluate various highlighting LSTM networks. results obtained demonstrated LSTM-based model outperformed task prediction. Specifically, achieved an accuracy 0.9463, additional metrics loss 0.21, 0.93, precision 0.29, recall 0.71, F1-score 0.42, MSE 0.07, RMSE 0.26. In conclusion, demonstrates is highly effective predicting congestion, surpassing other architectures Transformer. integration into simulation environment showed real-time traffic information can significantly improve management. findings support utility sustainable planning intelligent management, opening new perspectives future

Improving AODV with TOPSIS Algorithm and Fuzzy Logic in VANETs DOI
Esmaeil Amiri, Reza Hooshmand

Опубликована: Апрель 1, 2019

The ad-hoc on-demand distance vector (AODV) routing protocol is one of the most widely used protocols in VANETs. AODV finds shortest path that not desirable networks with high mobility. In addition, AODV, request messages are broadcasted by source and middle vehicles, which increases overhead. However, this paper, each vehicle selects reliable neighbors order to send request. This selection based on Technique for Order Preference Similarity Ideal Solution (TOPSIS) algorithm. As a result, destination receives paths uses fuzzy algorithm select best route from perspective failure among all received routes. Simulation results show proposed method has lower end-to-end latency higher throughput than AODV.

For creating a mobile network, the moving cars consider as nodes in Vehicular Ad-Hoc Networks (VANETs). Each participating car is turned into wireless router VANETs that allows connecting and network. To improve comfort safety of driving automotive users, vehicular environment system develops systems using access. The channel congestion causes degradation quality service such cases with higher vehicle density. real-time reliable communication required for various applications VANETs. dense traffic network has included one major challenges avoiding channels’ degradation. provide efficient operation, most studies are recommended to use appropriate control methods. It’s important note many mechanisms not implemented event-driven messages. Based on probability approach estimation, CFRS-CP-Congestion free route selection introduced minimizing total number data flow packets passing through congested nodes. At each node, estimated proposed technique CFRS-CP based link quality, MAC overhead, neighbour density & velocity. Then, used assessment. value appended comparison. All available routes assessed which results routing path every round communication. simulation prove method decreases end delay by 32% improves PDR up 30% throughput 45% compared existing protocols.

Vehicular networks are getting an important technology in the traffic system. VANET simply means vehicles connected or interlinked wirelessly to interchange information. By implementing IDS VANETs we able control and mitigate attacks, like Denial-of-Service attacks which can cause disturbances cannot communicate with each other share information about anything, lead disturbance problems. This a major accident between vehicles, harming human life big damage. So, implementation network analyse incoming outgoing of vehicles. It gives alerts if any malicious activity going on so proper steps be taken these prevented increase transportation safety security. In this review paper, reviewed papers related area provided theoretical idea how implement system so, secured prevent damage caused by attack.
