Abstract
Continuous remote monitoring of a patient’s health condition in dynamic environment imposes many challenges. Challenges further get multiplied based on the size of body area sensor network. One such challenge is energy efficiency of sensors. Maintaining longer life of all nodes, especially who participate in communicating vital signals from one network to another towards the base station is very important. In this work, an energy efficient communication protocol for the wireless body area network (WBAN) is proposed. The essential characteristics of the protocol are: random deployment of nodes, formation of clusters, node with high signal to noise ratio (SNR) as cluster head (CH), random rotation of CHs within each cluster, and so on. The developed algorithm is simulated in MATLAB by varying the number of nodes and networks. Obtained results are compared with some of the recent and most relevant existing works. It is found that there is an enhancement in the network lifetime by 19.5%, throughput by 12.61% and average remaining energy by 57.21%.
Highlights
The usage of information and communication technology (ICT) in healthcare sector is not so widely visible even in the pandemic
Simulations were carried in MATLAB R2019b and performance analysis is compared with various algorithms such as EELEACH, distributed power efficient clustering (DEEC), threshold sensitive power efficient sensor network protocol (TEEN) and clustering routing protocol for WBANs (CRPBA)
Due to limited energy, complicated channel conditions, different body postures and data rates, the communication protocols developed for wireless sensor networks are not appropriate to wireless body area network (WBAN)
Summary
The usage of information and communication technology (ICT) in healthcare sector is not so widely visible even in the pandemic. People even in urban areas require doctor appointment and physically visit them if they have any health problem. This has been in practice for a long time and continues even now. It is limited to a very few individuals who can somehow monitors some of his/her body parameters using smart watch, band, and so on. During this pandemic situation, when social distancing has become very important, health industry should have seen significant growth in terms of usage of monitoring devices and techniques.
