Ensuring QoS in Wireless Body Area Network: A Review


Objectives: Wireless Body Area Networks (WBANs) have gained immense popularity among researchers and this field has also touched the health sector. In this paper we have analyzed the various methods that are used to ensure the QoS in body nodes in WBANs. Methods/Statistical Analysis: The better functioning nodes with longevity of the battery nodes help to exchange the messages between the nodes uninterruptedly. Various works are presented each for improving the quality of one part or another of the network. The importance of the various methods and how these have benefitted in the better management of the sensor nodes has also been presented. The review of the researches that are undergoing in this field has been given. Findings: The body nodes work more efficiently if the interrupted energy supply is provided to them. Energy can be collected from the body movements also and can prove to be more beneficially limiting the health constraints of removing batteries again and again. Some scheduling algorithms can reduce the interference between the nodes and the routing protocols can manage the data traffic among the WBAN. The power optimizing techniques reduce the power consumption and the data loss. So many techniques provide the much needed quality of service in WBAN. Novelty/Improvement: The paper brings out various techniques which assist in better WBAN thus reinforces the use of wireless sensors in the health domain with better quality.
