Critical Data-Based Incremental Cooperative Communication for Wireless Body Area Network

Abstract

Wireless Body Area Networks (WBANs) are single-hop network systems, where sensors gather the body’s vital signs and send them directly to master nodes (MNs). The sensors are distributed in or on the body. Therefore, body posture, clothing, muscle movement, body temperature, and climatic conditions generally influence the quality of the wireless link between sensors and the destination. Hence, in some cases, single hop transmission (‘direct transmission’) is not sufficient to deliver the signals to the destination. Therefore, we propose an emergency-based cooperative communication protocol for WBAN, named Critical Data-based Incremental Cooperative Communication (CD-ICC), based on the IEEE 802.15.6 CSMA standard but assuming a lognormal shadowing channel model. In this paper, a complete study of a system model is inspected in the terms of the channel path loss, the successful transmission probability, and the outage probability. Then a mathematical model is derived for the proposed protocol, end-to-end delay, duty cycle, and average power consumption. A new back-off time is proposed within CD-ICC, which ensures the best relays cooperate in a distributed manner. The design objective of the CD-ICC is to reduce the end-to-end delay, the duty cycle, and the average power transmission. The simulation and numerical results presented here show that, under general conditions, CD-ICC can enhance network performance compared to direct transmission mode (DTM) IEEE 802.15.6 CSMA and benchmarking. To this end, we have shown that the power saving when using CD-ICC is 37.5% with respect to DTM IEEE 802.15.6 CSMA and 10% with respect to MI-ICC.

WBSN in IoT Health-Based Application: Toward Delay and Energy Consumption Minimization

“…Incremental cooperative communication with multiple traffics for WBSN is proposed in our previous work [25], which discussed a transmission selection issue to support both normal and critical traffics. However, cognitive cooperative communications with multiple traffics are not considered in [25]. In this paper, we continue to study the incremental cooperative communication with multiple traffics for WBSN to improve the throughput and energy consumptions.…”

IoT for health-based system: analog network coding with energy harvesting

“…The technology of WBSN can be considered as a set of appliances that are light and of lower power, accompanied by a transceiving device that utilized for monitoring the essential indications come off people. All of the WBSN's sensors are able of gathering mental indications like EEG and ECG, besides BT as well as movement and forwards the gathered indications towards coordinator node which can be abbrivated as CN on a medium carried by radio or microwave frequencies, or by HBC, that is human body channel to be analyzed more as well as inspecting [6]. The patterns of WBSN have the capability to give extended term health-care observing of human and there will not be any need of limiting their capability of moving or the efficacy.…”

Energy harvesting Internet of Things health-based paradigm: Towards outage probability reduction through inter–wireless body area network cooperation

“…Every sensor in the WBSN can gather physiological signals such as electrocardiogram (ECG), electroencephalogram (EEG) and forward these signals to the coordinator node (CN) over a wireless medium or human body channel (HBC) for further analysis and inspection. 6 WBSN paradigms are capable of giving long-range healthcare monitoring without constraining a person's mobility or activity. These paradigms are used to create intelligent and inexpensive healthcare monitoring to be used for the diagnostic procedure.…”
