Node Density Analysis for WBAN Schemes in Terms of Stability and Throughput

Wireless sensor applications have resulted in significant advancements in the medical sector known as body area networks. They are being heavily employed by wearable monitoring systems for detection of symptoms and indicators in order to counter harmful medical conditions while they are innocuous. The successful delivery of data whether normal or critical from the patient to his medical practitioner is still a tedious task. Various attempts at designing suitable protocols for WBANs have been made by researchers at different network layers. In this work, we have tried to present an overview of the working methodology of WBAN field, its applications, and various routing protocols designed for WBANs. What should be a suitable number of nodes to be deployed on a human body is still a challenging issue. We have considered three popular routing schemes of WBAN and presented an analysis with varying node deployments to judge their performance. The three schemes considered are SIMPLE, LAEEBA, and EENMBAN.
