Effective transmission of critical parameters in heterogeneous wireless body area sensor networks

摘要

Wireless body area networks have great potential to change the future of remote and personalised healthcare technology by embedding smart devices to provide real-time feedback. In this article, proposed a threshold-based routing concept to route only the critical data of bio-sensors during an emergency condition of a patient. Sensor nodes attached to the body, sense and forwards patient's vital sign's data based on the standard thresholds applied during the routing process. Depending on variations in the sensed data, the energy parameters are calculated and data are routed to the coordinator node for further communication. An efficient node is selected based on the least cost value that depends on high residual energy and less distance to sink. From the results obtained, the proposed technique provides improvements in terms of energy, stability period, network lifetime, throughput, path loss and packet delivery ratio compared to existing multi-hop routing techniques.
