Human Energy Harvesting

Wireless body area network (WBAN) is developed as a result of Wireless personal area network (WPAN), in which various interconnected Body Node (BN) communicates near and around human body. There are many differences between the WBAN and WPAN i.e distribution, density and mobility. Due to redundant nodes, BN in WBAN are less dense. In WBAN, Body node are implanted inside and on human body to measure physiological signals using different sensors i.e Electro cardio graph (ECG), electroencephalogram (EEG), Blood pressure, temperature etc) of body which collects data and send it to sink node. Earlier researchers have used either piezoelectric harvester, solar or temperature gradient based. But in this paper optimization technique using combination of Peltier and Piezoelectric human energy harvesting is studied. By developing an algorithm, extensive simulation can be performed considering four human body gestures (relaxing, walking, running and fast running). Overall Quality of Service (QoS) including average (packet loss, end-to-end delay, throughput) and overall detection efficiency is studied.

Area Network

A technology of wireless body area network (WBAN) was invented in order to enhance the quality of healthcare management as well as to determine faster disease prevention. However, to obtain the real-time data of images and videos from inside the human body, an implantable device is required. Currently, the Medical Implant Communication System (MICS) is used, but, this system has limited data rate which is a narrow-band of 402 – 405 MHz. Thus, this study on Ultra Wideband (UWB) for implanted device is conducted as UWB offers a wide transmission bandwidth as well as high data rate. Knowledge of radio wave propagation behaviour inside human body is needed to perform the implantation. Past researches related to this topic are limited and those conducted focused only on the human torso. This paper aims to provide a better understanding on the characteristics of radio wave propagation inside the human body by using an implantable device at UWB frequency. It is also hoped that this study could be used as reference for future research on this subject.

A dual-band on-body antenna for a wireless body area network repeater system is proposed. The designed dual-band antenna has the maximum radiation directed toward the inside of the human body in the medical implantable communication service (MICS) band in order to collect vital information from the human body and directed toward the outside in the industrial, scientific, and medical (ISM) band to transmit that information to a monitoring system. In addition, the return loss property of the antenna is insensitive to human body effects by utilizing the epsilon negative zeroth-order resonance property.

Wireless Body Area Network (WBAN) is a collection of miniaturized sensing nodes and coordinator nodes. These sensing nodes are placed in, on and around the body for uninterrupted monitoring of physiological data for medical applications. The main application carrier of WBAN is the human body and due to human body movement and physiological changes, the WBAN traffic fluctuates greatly. This network traffic fluctuation requires good network adaptability. In addition to traffic fluctuations, energy consumption is another key problem with WBANs as sensing nodes are very small in size. This paper design a reliable protocol by extending the MAC protocol for reducing energy consumption, PAP algorithm to decide data transmission rate and JOAR algorithm to select the optimize path for the data transmission. The performance of the algorithm outperforms other state of art algorithms to shows its significance.
