While WLAN continues to be predominantly data-centric, the necessity of Voice over Internet Protocol (VoIP) over Wireless Fidelity (WiFi) or VoWiFi cell capacity analysis in infrastructure-based WLAN plays a vital role. We employed arbitration inter-frame space (AIFS) for assessing channel state before sending real-time data from one user equipment to another, and short inter-frame space (SIFS) for transmitting Request To Send (RTS), Clear To Send (CTS) and Acknowledgement (ACK) frames to study the VoWiFi cell capacity. We have proposed analytical approaches to estimate the cell capacity of an IEEE 802.11be WLAN standard Assess Point (AP) providing VoWiFi service considering well known vocoders such as G.723.1 and G.729. To minimize the call bandwidth, we employed the compressed RTP (cRTP) protocol.

The novel corona virus had entirely shattered all segments of life in the entire world. In the medical sciences, patients are more advised to take telemedicine supports. Cardiac patients are very much prone to corona virus. They need to transmit confidential medical data for their online treatments. Such heterogeneous cardiac information is to be protected with patients’ confidentiality. It is very noteworthy to impose high security features on the COVID-19 “New Normal” telecardiology. In this paper, we have designed a cryptographic system based on metaheuristic Harmony search algorithm and tree parity machines. It has been proposed to counter attack against different security hazards in online medical transactions during this tremendous flooded COVID-19 time. The proposed method has been modularized into four modules. These are: Neuro-Metaheuristic Session Key (NMSK) generation, Cryptographic Engineering, Frame format generation, and authentication and decryption phase. Harmony search with tree parity machines were used to generate the key i.e. NMSK. A new state-of-art sharing was proposed to dilute the information contents inside the telemedicine networks against the intruders. Moreover, the proposed state-of-art sharing exhibits the complete bi-partite graph property. A rigorous frame format has been placed before the encrypted message inside the COVID-19 telecardiology. Different types of statistical and mathematical tests were carried out on the proposed technique to prove its efficacy. Thus, the proposed cryptographic system acts as a reinforcement of security mechanism in COVID-19 telecardiology.</p>","PeriodicalId":23827,"journal":{"name":"Wireless Personal Communications","volume":"5 1","pages":""},"PeriodicalIF":2.2,"publicationDate":"2024-09-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142257757","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}
