At present, the research enhances underwater communication through random deployment algorithms. However, current research has focused on designing node deployment algorithms for underwater sensors, underwater relays, or surface stations, which leads to poor network performance. Therefore, it is critical to consider all underwater nodes while designing an efficient node deployment algorithm to guarantee meeting the QoS requirements of underwater applications. To address these issues, this paper proposes the Distributed Deployment Optimization algorithm using Grid-based Depth Adjustable (DDOGDA) that relies on the minimum number of underwater nodes to maximize coverage, connectivity, and Energy Efficiency (EE) while reducing the Total Collisions (TC). In DDOGDA, the underwater nodes are placed within their Sensing Range (SR) to maintain network coverage and connectivity. The proposed algorithm takes into account multiple factors, including deployment strategies, Geographical Information System (GIS) data for the Solomon Islands, non-environmental factors, and the unique characteristics of underwater nodes. We find that the grid-based distributed node deployment algorithm can achieve higher performance than random and geometric deployment algorithms. Simulation results confirm that DDOGDA can maximize coverage and connectivity while minimizing TC. Moreover, we compare DDOGDA with random, tetrahedron, cuboid, triangular, and adaptive triangular deployment algorithms in terms of coverage, connectivity, TC, and EE and demonstrate that DDOGDA outperforms state-of-art methods.","PeriodicalId":23827,"journal":{"name":"Wireless Personal Communications","volume":"51 1","pages":""},"PeriodicalIF":2.2,"publicationDate":"2024-08-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142188924","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}

It has been considered one of the main keys of current and next-generation wireless communications networks like 5G and 6G. Effectively, it can handle demand growth and maintain better spectral efficiency (SE). However, the power consumption of a large number of access points (APs) significantly influences the performance which is one of the main points in CF-MMIMO. In this research, improving energy efficiency (EE) is considered while maintaining a high quality of service in the downlink (DL) transmission by optimizing the power allocation of users. This is achieved through the use of the sequential convex approximation method to optimize DL power control coefficients with zero-forcing (ZF) precoding. Moreover, the power consumption of the backhaul lines is minimized by implementing a novel dynamic AP selection method. This method ensures that each user is assigned appropriate APs without quality-of-service degradation and reliable spectral efficiency. Reducing overall power, which leads to improving the EE, is essential for cost savings, better coverage, and carbon emissions. The outcome of the optimized power allocation demonstrates a 43.7% improvement in energy efficiency when comparing the ZF with the conjugate beamforming approach. The results of the suggested AP selection demonstrate a 20.8% improvement in EE compared to the scenario without AP selection. Additionally, there is a 7.2% enhancement in EE compared to a previous study that used fixed AP selection with a signal-to-noise ratio of 10 dB. There is a tradeoff in the total SE when AP selection is used since it tends to decrease. This degradation can be effectively controlled through the careful selection of suitable APs.","PeriodicalId":23827,"journal":{"name":"Wireless Personal Communications","volume":"23 1","pages":""},"PeriodicalIF":2.2,"publicationDate":"2024-08-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142188922","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}

At the same time, users need high throughput and link reliability. The forthcoming generation of wireless communication will have to deal with some core requirements for serving large number of users simultaneously, upholding high throughput for each user, assuring less energy consumption, etc. Inter-user interference has a major impact when a wireless communication link has a large number of users. To maintain a particular desired quality of service, sophisticated transmission mechanisms such as interference cancellation need be implemented. As a result, MU-massive MIMO with extremely huge antenna arrays is recommended. The term \"MU-massive MIMO\" refers to a system with hundreds or thousands of antennas servicing tens of thousands of customers.Inter-user interference was greatly decreased once the channel vectors were closely orthogonal. As a result, high data rates can be supplied to multiple users at the same time. In this work, researcher investigated performance evaluation of a MU-massive MIMO utilizing different precoding schemes (like, MMSE, ZF, MRT) over nakagami-m fading channel with CSI at base station and users’ terminal.

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 (e2e) Delay, Throughput, and packet overhead. This paper introduced a new Customized hunger’s foraging honey badger with a Dynamic multi-objective non-sorted genetic algorithm (CHFHB-DMNSGA). Also, the gateway selection is done under two objectives: Vehicular gateway mobility and receiver signal strength, respectively. Finally, the paper presented a comparative assessment to validate the effectiveness of the adopted algorithm CHFHB-DMNSGA over the other algorithms like R-NSGA-II, NSGA-III, NSGA-II, HBA, HGS, ABC, FF, CSO, ACO, LA, MHB-GA, GA-FF, and HFCHBO.","PeriodicalId":23827,"journal":{"name":"Wireless Personal Communications","volume":"13 1","pages":""},"PeriodicalIF":2.2,"publicationDate":"2024-08-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141968862","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}

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. This would facilitate timely treatment of the accident victim(s).","PeriodicalId":23827,"journal":{"name":"Wireless Personal Communications","volume":"74 1","pages":""},"PeriodicalIF":2.2,"publicationDate":"2024-08-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141968864","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}

With the performance saturation under different camera views and environmental settings, the research focus for person Re-ID has facing more challenging issues. Some of them are illumination, pose variation, viewpoint changes and, occlusions. To overcome these issues, we proposed a novel feature extraction method called GLOGT and pose learning-based re-identification procedure in our previous research papers. Later we came to know that the image-based analysis is more important to prove the efficiency of a novel person re-identification method. So here we conducted some important experiments to analyze the efficiency of the proposed techniques using the benchmark datasets. From the result analysis, it shows that the proposed techniques outperforming other existing techniques with a good accuracy level. Since the pose estimation-based method extracting the features based on the pose priority, reduces the training testing comparisons also. Since the GLOGT feature is a combination of three types of feature representation, one feature suppresses due to some issues, at that point the remaining will dominate and gives higher accuracy for identification.","PeriodicalId":23827,"journal":{"name":"Wireless Personal Communications","volume":"9 1","pages":""},"PeriodicalIF":2.2,"publicationDate":"2024-08-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141968867","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}

Structural modifications to the initial antenna element, including the T-shaped structure and integrated stub between quad rings, enable circular polarization in the GPS L1 band. With simulated total radiation efficiency exceeding 60% at four bands, numerical simulations and physical fabrication on an FR-4 substrate are followed by antenna radiation measurement in an anechoic chamber. The measured gain at 1.575 GHz, 2.6 GHz, 4.8 GHz, and 8 GHz is 1 dBi, 2.2 dBi, 3.2 dBi, and 3.8 dBi, respectively. Additionally, ray tracing techniques evaluate the antenna’s performance when mounted on a car, considering interactions with other vehicular antennas and infrastructure in urban propagation scenarios. Urban propagation analysis illustrates efficient operation, characterized by minimal delay time, favorable line of sight, and controlled path loss at frequencies 2.6 GHz and 4.8 GHz.
