Abstract: Wireless Body Area Networks (WBANs) instigated healthcare applications offer valuable contributions at monitoring, diagnostic, or therapeutic levels. It deals with real-time medical information gathering obtained from different sensors with secure data communication and low power consumption. Given the present situation, the aim of this work is to design a protocol that satisfy the main requisites of WBANs for the application of healthcare with regard to patient mobility, secured and reliable data, power consumption, and the requirements needed for large amounts of sensor nodes to coexist in a relative small space. EUROTA is deploys a hierarchical, multihop method which instigates the clustering in the routing. This algorithm considers two primary aspects: energy-awareness and node coverage preservation mechanisms. It utilizes the metrics of the link credit (LD) and signal strength (SS) to assess the node in-between distance. The method deploys the cluster based routing for the WBAN routing. The cluster will have the Cluster Head (CH), Cluster Nodes (C1,C2,…Cn), Cluster Message Agent (CMA) and Base Station (BS). The selection of CH can be done dynamically based on the minimal nearest distance and maximum residual energy which enhances the node lifetime. The proposed EUROTA algorithm is implemented with MATLAB. The power consumption is tested for the comparison. Dead and alive nodes are also compared for determining the performance. Number of packets sent to the sink, packets dropped, residual energy, path loss are monitored and compared. Finally delay factor is instigated for the performance determination.
