The Extent Analysis Based Fuzzy AHP Approach for Relay Selection in WBAN

摘要

A revolutionary technology in the field of healthcare monitoring system to manage illness for maintaining wellness by concentrating on prevention and early detection of disease are popularly known as Wireless Body Area Networks (WBAN) which is highly localized wireless networks along with different sensors placed in the human body or surface mounted on the particular places of the body. Though WBAN is a specially designed sensor network to implement ubiquitous and affordable health care autonomously, anytime and anywhere, it faces numerous challenges like frequent link loss due to postural body movement, size, and complexity of the sensors, channel condition, and power consumption. This letter provides FAHP using the Extent Analysis scheme for relay node selection that prioritizes the vagueness of the decision-makers during the relay node selection procedure.
