Abstract
This study presents a survey of the current issues, application areas, findings, and performance challenges in wireless body area networks (WBAN). The survey discusses selected areas in WBAN signal processing, network reliability, spectrum management, security, and WBAN integration with other technologies for highly efficient future healthcare applications. The foundation of the study bases on the recent growing advances in microelectronic technology and commercialization, which ease device availability, miniaturization, and communication. The survey considers a systemic review conducted using reports, standard documents, and peer-reviewed articles. Based on the comprehensive review, we find WBANs faces several operational, standardization, and security issues, affecting performance and maintenance of user safety and privacy. We envision the increasing dependency of future healthcare on WBAN for medical and non-medical applications due to internet connectivity advances. In this view, despite the WBAN advantages in remote health monitoring, further studies need to be conducted for performance optimization. Therefore we finalize our study by proposing various current and future research directions and open issues in WBAN’s performance enhancement.
Highlights
Technology advances in the areas, including miniaturized electronic devices, application software, human–machine interaction, wireless communication, and other smart technologies, support social-economic development and ease access to social services, such as health monitoring in normal and critical conditions.The invention of the internet and the increasing number of internet users and smart devices across the globe materialized the deployment of remote access to various mobile services through the internet of things (IoT) [1]
The types of attack include the use of shared authentication keys in multi-hop communication schemes, the use of counterfeit acknowledgment packets, signal jamming, and distributed denial of service (DDoS) due to limited wireless body area networks (WBAN) device memory operating in the big data [22]
Future demands for packet routing, energy efficiency, and quality of service call for robust solutions to address challenges related to mobility, coexistence and inter-BAN interference [16], in this view, problems related to data frame variation, incomplete data, data flow rate, packet collisions, faults, malicious attacks, and resource utilization for distributed BAN need to be revisited at the intersection of big data for B2B connectivity
Summary
Technology advances in the areas, including miniaturized electronic devices, application software, human–machine interaction, wireless communication, and other smart technologies, support social-economic development and ease access to social services, such as health monitoring in normal and critical conditions. Universal deployment of the WBAN for health monitoring needs low cost devices, comfortability, improved accuracy, integrity, extended memory systems, information security, user safety, proper spectrum management, link reliability, mobility convenience, and energy efficiency. This survey aims to discuss some of the driving and open performance issues to the current and future WBAN application technologies in improving efficiency through signal processing with concerns for packet processing and queuing delays, information security, and reliability with their contribution to WBAN operational performance. We discuss essential features to be included for the transmission channel model and WBAN security-related issues
