Lifetime Enhancement and Reliability in Wireless Body Area Network

Abstract

The wireless body area network (WBAN) consists of wearable or implantable sensor nodes, which is a technology that enables pervasive observing and delivery of health-related information and services. The network capability of body devices and integration with wireless infrastructure can result in pervasive environment deliver the information about the patients to health care service providers. WBAN has a major part in e-health observing system. Due to sensitivity and critical of the data carried and handled by WBAN, reliability becomes a critical issues. WBAN loads a high degree of reliability as it openly affects the quality of patient observing. A main requirement is that the health care professionals receive the monitored data correctly. Thus reliability can be measured to achieve reliable network are fault tolerance, QoS, and security. As WBAN is a special type of WSN. The objective is to achieve a reliable network with minimum delay and maximum throughput while considering power consumption by reducing unnecessary communication.
