WBAN monitors elderly people or patients suffering from any long-lasting diseases from their place without being hospitalized, saving critical time transportation delays and admission costs. Wireless medical devices are attached or implanted in the human body to sense medical-related data and further transmit it for medical services in an unsecured wireless medium. These sensing medical devices are miniature-sized with a limited battery source, so energy should be exploited carefully. The sensing devices deplete their energy more during data transmission. Efficient energy exploitation and assuring data security and privacy in WBAN are highly recommended. Data to be transmitted from the sensing device are compressed before transmission to reduce the number of data transmissions and save energy. In this paper, to attain efficient energy exploitation, Lightweight Fixed Binary Golomb (LFBG) data compression is performed at each sensor before transmission, and further to guarantee the privacy and security of the data, Lightweight Symmetric Mutual Authentication (LSMA) protocol is implemented. The LFBG compression with the least computation saves up to 84% of energy, and LSMA with the least computation and transmission authenticates and also shares the session key securely.</p>\u0000 </div>","PeriodicalId":13946,"journal":{"name":"International Journal of Communication Systems","volume":"38 9","pages":""},"PeriodicalIF":1.7,"publicationDate":"2025-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143914124","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}

However, one of the key challenges in satellite communication is the efficient use of bandwidth and maintaining high-quality signal reception under varying environmental conditions. Traditional satellite communication systems rely on fixed antennas that may not adapt effectively to changing atmospheric conditions, signal interference, or satellite position variations, leading to suboptimal performance. To overcome these limitations, reconfigurable antennas (RAs) have emerged as a promising solution, offering flexibility to adjust their operating parameters. This research aims to address this challenge by employing a rain optimization algorithm (ROA) to optimize the parameters of a reconfigurable antenna for satellite communication. The optimization-based reconfigurable antenna by the intrusion of Flame Retardant-4 (FR4) substrate is proposed with a thickness of 1.4 mm, a permittivity of 4.4, and a tangent loss of 0.019, respectively. Here, the L-shaped slots have been embedded in the ground plane of dimension 20 × 20 to enhance the antenna performance. ROA is established to optimize the parameter of the designed antenna. Uniformly, the high-pass filter (HPF) is initiated in the antenna design to eliminate the undesired frequencies. The parameters of the designed antenna, such as current distribution, gain, return loss, directivity, and radiation pattern, are simulated by the high-frequency structure simulator (HFSS) tool. For satellite applications, the proposed optimized antenna achieves a gain of 8.75 dB, a bandwidth of 9.70 MHz, and a return loss of −16.03 and −18.982 at the resonance frequencies of 9.7 and 29.5 GHZ.

Existing congestion control methods struggle with unpredictable traffic patterns and fluctuating node energy levels, leading to incorrect routing decisions and shortened network lifespans.
