The significant usage of VANET is to offer comfort and safety to drivers in road environments. VANET provides a communication framework that aids in minimizing accidents. Also, sharing data in VANET is time-sensitive and necessitates vigorous and quick network link formation. However, appropriate routing is critical to avoid the streaming issues that occur in VANET applications. This research area is of great concern to the researchers, and this work intends to propose a new Cluster-based VANET routing model with steps like (a) optimal cluster head selection (CHS) and (b) appropriate gateway selection for data transmission. Here, the optimal CHS takes place considering the Packet delivery ratio (PDR), mean routing load, end-to-end<b> (</b>e2e) Delay, Throughput, and packet overhead.

Early detection of roadway accidents is beneficial as help can be directed to the accident site quickly, saving the lives of the injured. With this goal, an intelligent accident detection system is proposed in this paper using a Vehicular Adhoc Network model. Each vehicle has an on-board unit with multiple sensors in the proposed work. Outputs of these sensors, which monitor the condition of the driver and the vehicle, are input to a fuzzy logic controller for quick detection of an accident. The proposed system is validated by designing and implementing a hardware prototype. When an accident is detected, the proposed hardware uses a low-range radio (LoRa) transceiver network to send messages to a central server. After receiving the message from a vehicle, the server can inform a nearby ambulance. It can also identify the shortest path to a nearby hospital using Dijkstra’s algorithm and inform the ambulance.

In the outdoor application, GPS signals identifies the exact location or points of the user, but it is not true in indoor scenarios. To overcome this issue there are various techniques have been devised to predict the position and identify the location of the user in the indoor application. These include attaching sensors to the shoes or suites or ceiling of the building and using WIFI signals to predict the position and navigate user to the destination. But not all the time this is possible as the sensors may get damaged and signal interferences may lead to large accumulated errors in the results. This paper proposes a novel technique to predict the position and navigate the user making use of the sensors present in the smartphone. Use of smartphone eliminates the need for external sensors to be attached to the shoes or suits, as it has inbuilt magnetometer, accelerometer, and gyroscope. The data generated by these sensors are used to estimate the pitch and roll values and also the heading information. The step count and the time at which the user performs each step are calculated using peak detection algorithm. A rule-based algorithm is proposed to estimate the step length and the smart phone beacon signals are used to provide the heading information. A voice based guiding facility is also built in to alert the user in case he selects the wrong path. With all these features, the proposed system certainly helps the user to navigate correctly from source location to the intended destination. The experiments are carried out in different scenarios under various realistic conditions and the results displays that, the proposed method achieves a high position accuracy with significant reduction in the error (less than 2.5%) and performs well compared to the conventional estimation methods. The performance is assessed in terms of displacement and root mean square error and compared with the position-estimation method (Poulose in IEEE Access 7: 11165–11177, 2019).</p>","PeriodicalId":23827,"journal":{"name":"Wireless Personal Communications","volume":"188 1","pages":""},"PeriodicalIF":2.2,"publicationDate":"2024-08-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141968879","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Federated learning is a popular solution for decentralized training that preserves data, but it can also be susceptible to federated poisoning attacks caused by malicious clients. This work proposes a clustering-based client selection strategy to identify malicious clients based on their run time, followed by a trigger-set-based encryption mechanism that verifies the authenticity of the clients. This approach allows unreliable clients with plain text-based gradients to be ignored by the global model. The methodology was evaluated using the IoT23 dataset, and its efficiency, robustness, false alarms, and ability to handle some of the poisoning attacks that occur due to tuning and pruning were verified. The LeNet and DeepCtrl algorithms were used to determine detection accuracy, and after the implementation of a watermarking strategy, the detection accuracy improved significantly. For the DeepCtrl classifier, the detection accuracy improved from 89.90 to 99.8%, while for the LeNet classifier, it improved from 86.21 to 96.54%.

For 5G to function well, it necessitates little delay, a fast rate of data transfer, and the ability to handle a large number of connections. This demanding service requires the allocation of resources in a dynamic manner, while maintaining a very high level of reliability in terms of Quality of Service (QoS).The applications like autonomous driving, telesurgery, etc. have stringent QoS demands and the present design of slices is not suitable for these services. Therefore, latency has been regarded as a crucial factor in the design of the slices. Conventional optimization algorithms often lack robustness and adaptability to dynamic environments, getting stuck in local optima and failing to generalize to varying conditions. Our solution utilizes Reinforcement Learning (RL) to allocate resources to the slices. The utilization of restricted resources can be optimized through the reconfiguration of slices. The ability of RL to acquire knowledge from the surroundings enables our solution to adjust to varying network conditions, enhance the allocation of resources and improve quality of service over a period of time for different network slices. This study introduces the Deep Actor Critic Reinforcement Learning- Network Slicing (DACRL-NS) technique, which utilizes Deep Actor Critic Reinforcement learning for efficient resource allocation to network slices. The objective is to achieve optimal throughput in the network. If the slices fail to meet the minimum criteria, they will be omitted from the allocation. With increasing training episodes, our Actor-Critic algorithm enhances average cumulative rewards and resource allocation efficiency, demonstrating continuous learning and improved decision-making.The simulated suggested system demonstrates an average throughput improvement of 8.92% and 16.36% with respect to the rate requirement and latency requirement, respectively.
