Efficient two tier transmission power control algorithms to reduce co channel interference in wireless body area networks

Abstract

newline Wireless sensor network (WSN) is an operational area of research newlinedue to its wide applications in health care, military, and environmental newlinesurveillance. Wireless body area network (WBAN) is a subdomain of WSN. newlineRapid development in low-powered nano and microtechnology makes tiny newlinemedical sensors to be placed on the surface of the body and implanted inside newlinethe body. The main aim of the WBAN is to diagnose the disease by predicting newlinethe symptoms of the disease in the early stage and communicating it to newlinedoctors and caretakers. WBAN sensors collect the heart newline(electrocardiography), brain electrical activities (electroencephalographs), newlineblood sugar, blood pressure, body temperature, oxygen saturation, and CO2 newlineconcentration using wearable sensors. It is worth mentioning that WBANs newlinerequire only a small number of nodes for operation. Therefore, the protocols newlineused in the MAC and network layer are a lot simpler than traditional WSNs. newlineWBAN has complex channel conditions due to on-body and off-body newlinecommunication between nodes and coordinators.
