However, the limited resources and dynamic nature of WBANs pose significant challenges to designing efficient and reliable routing protocols. To address these challenges, the proposed work suggests a thermal-aware, energy-efficient, and congestion-aware routing protocol (TECRP) for WBAN. TECRP focuses on improving transmission in both inter-WBAN and intra-WBAN scenarios. It addresses three key Quality of Service (QoS) parameters: energy efficiency, node temperature, and congestion, aiming to enhance overall WBAN communication efficiency. To achieve all these parameters, the algorithm is considered a multi-objective problem. The analysis shows that the temperature rises and delay increases with the number of data transmission, but the multi-objective approach helps to mitigate such effects. The result analysis shows that the path loss values fluctuate with increasing data transmission and network traffic. But the temperature rise increases with more data transmission and larger packets. On the other hand, the Packet Delivery Ratio (PDR) decreases with an increase in data transmission and with larger packet sizes. This shows that with higher congestion ratios, a higher likelihood of packet loss is seen. But in overall performance, the proposed TECRP shows better efficiency and congestion management as compared to other existing state-of-art-models and achieves high PDR, and minimizes packet loss. The proposed approach shows 0.42% improvement in energy efficiency as compared to existing approaches.</p>","PeriodicalId":23827,"journal":{"name":"Wireless Personal Communications","volume":"166 1","pages":""},"PeriodicalIF":2.2,"publicationDate":"2024-08-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141882994","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 application of wireless charging vehicle (WCV), wireless charging technology can be used to solve the energy problem of WSN. In the wireless rechargeable sensor network (WRSN), how to reasonably deploy the WCV has become a problem in planning. The existing studies only consider the impact of independent coverage contribution of a single node on the charging path planning, but do not consider the redundant coverage area that may occur when a single node works independently, resulting in a small or even zero coverage contribution of some nodes. This paper propose Improved Soft-k-Means Clustering Charging Based on Node Collaborative Scheduling (ISKCC-NCS) to keep the coverage quality of WSN. At first, this algorithm uses Improved Soft-k-Means to cluster WRSN, and realizes confident information coverage through collaborative sensing between adjacent nodes. The second, we evaluate the coverage contribution of each node to be charged and calculate the priority of the node. The third, we form new charging path by inserting and deleting tasks. At last, a carrier charging vehicle (CCV) is used to carry several micro charging vehicle (MCV) to each cluster to charge the sensor node.

Ensuring the trustworthiness of these sensors is essential to prolong the lifetime of the network. Additionally, dependable data transmission by sensor nodes is crucial for effective decision-making. Trust management approaches play a vital role in safeguarding industrial sensor networks from internal threats, enhancing security, dependability, and network resilience. However, existing trust management schemes often focus solely on communication behaviour to calculate trust values, potentially leading to incorrect decisions amidst prevalent malicious attacks. Moreover, these schemes often fail to meet the resource and dependability requirements of IWSNs. To address these limitations, this paper proposes a novel hybrid Trust Management Scheme called the Multi-layered Assessment System for Trustworthiness Enhancement and Reliability (MASTER). The MASTER scheme employs a clustering approach within a hybrid architecture to reduce communication overhead, effectively detecting and mitigating various adversarial attacks such as Sybil, Blackhole, Ballot stuffing, and On–off attacks with minimal overheads. This multifactor trust scheme integrates both communication-based trust and data-based trust during trust estimation, aiming to improve the lifetime of industrial sensor networks. Furthermore, the proposed MASTER scheme utilizes a flexible weighting scheme that assigns more weight to recent interactions during both direct and recommendation (indirect) trust evaluation. This approach ensures robust and precise trust values tailored to the specific network scenario. To efficiently process and glean insights from dispersed data, machine learning algorithms are employed, offering a suitable solution. Experimental results demonstrate the superior performance of the MASTER scheme in several key metrics compared to recent trust models. For instance, when 30% of malicious Sensor Nodes (SNs) exist in a network comprising 500 sensor nodes, the MASTER scheme achieves a malicious behaviour detection rate of 97%, surpassing the rates of other models. Even after the occurrence of malicious SNs exceeding 30%, the False Negative Rate (FNR) in the MASTER scheme remains lower than other models due to adaptive trust functions employed at each level. With 50% malicious SNs in the network, the MASTER scheme achieves a malicious behaviour detection accuracy of 91%, outperforming alternative models. Moreover, the average energy consumption of SNs in the MASTER scheme is significantly lower compared to other schemes, owing to its elimination of unnecessary transactions through clustered topology utilization. Specifically, with 30% and 50% malicious SNs in the network, the MASTER scheme achieves throughput rates of 150 kbps and 108 kbps, respectively, demonstrating its efficiency in challenging network scenarios. Overall, the proposed MASTER scheme ","PeriodicalId":23827,"journal":{"name":"Wireless Personal Communications","volume":"35 1","pages":""},"PeriodicalIF":2.2,"publicationDate":"2024-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141864867","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}
