Abstract
This paper offers a review of different types of Error Correction Scheme (ECS) used in communication systems in general, which is followed by a summary of the IEEE standard for Wireless Body Area Network (WBAN). The possible types of channels and network models for WBAN are presented that are crucial to the design and implementation of ECS. Following that, a literature review on the proposed ECSs for WBAN is conducted based on different aspects. One aspect of the review is to examine what type of parameters are considered during the research work. The second aspect of the review is to analyse how the reliability is measured and whether the research works consider the different types of reliability and delay requirement for different data types or not. The review indicates that the current literatures do not utilize the constraints that are faced by WBAN nodes during ECS design. Subsequently, we put forward future research challenges and opportunities on ECS design and the implementation for WBAN when considering computational complexity and the energy-constrained nature of nodes.
Highlights
Wireless body area networks (WBANs) is termed as a wireless network in and around the human body
We observed from the literature review that the researchers utilize standard techniques of error corrections to enhance reliability without considering the constraints that are faced in WBAN
Another case to consider is that the researcher uses lower rate Error-Correcting Codes (ECCs), Which enhanced the reliability when compared with higher rate ECC, but it does not consider the code rate during the result and discussion
Summary
Wireless body area networks (WBANs) is termed as a wireless network in and around the human body. This network combines the study of medical and communication technologies. It is anticipated that wearable and implant sensors used in WBAN will facilitate advanced way for human wellbeing monitoring [6]. The network is required to handle various types of data, including medical and non-medical. The network should provide ways to handle different types of data and delay requirements for those data. The interference that is caused by the existence of other networks should be considered during WBAN implementation [7]
